Chapter 1: Unexpected Guest
Objective: Destroy the Decepticons
You will use Bumblebee as the first character, try to familiarize yourself with the driving commands. When you are ready, go to the green arrow on the car in the lower left corner.
The impact of the meteorite will be marked by a large green cylinder, as soon as you arrive you will see the first four Decepticons very easy to beat.
Once you have eliminated everyone there will be a scene where you will see other enemies coming, use the same system as before and if you want to take a car or a light pole to throw at them.
Chapter 2: Guardian Angel
Objective: Eliminate all the Decepticons before they reach Sam
Here you will still use Bumblebee, Sam a human has some artifacts that interest the Decepticons, run like crazy towards his house hoping to get there before the enemy. You will find the house by following the direction of the green arrow that you will find on the map.
After the scene you have to eliminate the enemies chasing the car with Sam inside. The Drones are in vehicle form and will be heading towards Bumblebee. Initially there will be only two of them, you will have to hit them to make them become Robots and then you will have to fill the bar they will have. Go up to it or use your normal attacks to do it.
Drive towards the first enemy by hitting with your car, with a couple of shots you will reach the goal of transforming them. Now that both enemies have transformed you can destroy them.
It won't be over yet, there are three more drones that will reach the car. You will have to locate them with Bumblebee and intercept them before they can reach the objective. Drone locations are marked in red on the Map with the Decepticon symbol.
They will travel together so the best strategy will be to reach the car in the lead and stop it, then damage the others. When the enemies are all transformed and therefore no longer chasing the car go back and destroy them one by one.
If only one of the enemies reaches the machine the mission will end and you will have to start over. You should try a couple of times but the path that the enemies will take will be basically the same so when you know it you should be able to intercept them easily.
Chapter 3: Protect and Serve
Objective: Eliminate Barricade and get to Sam before Him
Bumblebee's main goal will be to get Sam to safety. Go to the school along the way to activate the next mission.
Watch out for Barricade, too strong to beat him with melee attacks. Stay away from him and use objects to throw at him to do him damage.
As soon as you hit it, you can get close to the enemy and use a couple of shots to damage it. After you take his energy out there will be a cutscene and Barricade is going to find Sam. Quickly move to the green dot (Sam) on the Map by following the arrow.
Get there before Barricade to fight him (if during the chase Barricade reaches Sam it will be Game Over and you will have to start over). Fight Barricade like the first time, attack with items and you should do it without problems.
When you're done with him, he'll head to the Power Station. You will have your final fight with him, the strategy will be the same by hitting him from afar with the white tanks very useful in this fight. Avoid the blows with his arms and immediately locate a Heart that will fill a part of Bumblebee's Energy that you can use if you find yourself in trouble.
Chapter 4: Air Control
Objective: to destroy the Radio Towers and the Power Plants
Optimus will give Bumblebee the coordinates and ask if the signal to the Communication Center is ready. The Radio Antennas and the Control Panels will disturb the transmission so you will have to deal with it.
The Radio Towers are marked on the map in red while the generators are marked with small lightning bolts. There will be a Tower in each of the two buildings in front of Bumblebee as well as a Ground Level Generator in each zone. Hit with your weapon to destroy the Towers.
Do the same or use melee attacks to destroy the generators. As soon as everything is destroyed, the countdown will begin. Move to the next area on the Map and destroy more Towers and Generators (you can have your Transformer climb up the building using the stick above).
When everything is destroyed you will have another minute to reach the Power Plant and clean up the area. (after the battle with Barricade it should already be almost completely destroyed). Destroy all the White Tanks to finish the mission.
More than what it seems
Chapter 1: Obstacle to Justice
Objective: Run through the city causing a diversion
Now you are in control of Jazz, take control of it and get Jazz to the green point for a scene. The goal will be to go from point to point at full speed by destroying certain structures and allowing the other Autobots to escape.
There will be yellow symbols on the map, move over each of them and drive through the purple light to continue the mission. Go through each of the checkpoints before the time runs out. After the third checkpoint Jazz will have to move to the red dot and destroy the building with the explosive icon.
After destroying three buildings the race will start again, hit the purple icon and then destroy the truck indicated by the red dot on the map. Move to two more checkpoints and destroy another truck.
Two more checkpoints, a building and two more checkpoints before finishing. As you run between the various areas, remember that it will be essential to pass the checkpoints. Transform into Robots to make sure you hit the purple light, when the cops and wagons move towards you, use your weapons to make your way.
Eventually it will be easier to destroy everything with kicks and punches than to use Jazz's weapon.
Chapter 2: A Friend in Need
Objective: Defeat the Decepticons
Jazz will be in Sector 7 in trouble. Optimus will call Ironhide to his aid. Find the green dot and drive there to activate the mission. After a scene, Ironhide will have to find Jazz. Find it by moving to the area with the green arrow on the Map.
Destroy all the enemies in the area (there are four of them) and then move on to the next battle zone. Throughout the mission you will see a mission at the top right of the screen. This bar represents Jazz's Life so if it ends you will lose the Mission.
The second battle zone will be slightly different, there are two easy Decepticons to take out while a third a bit tougher. The second is located next to the Truck that will have transformed into Ironhide. Melee attacks won't be very useful given the enemy's ability to dodge.
Use ranged attacks like with Barricade throwing anything you can find at him and when he stops hit him closely. Now he will go up the hill with the Police Station and jump over the fence. When he gets back on the road drive to the next Jazz position.
This time there will be a lot of small drones that will annoy you. The problem will be that they will automatically attack you and you will not be able to continue. Attack them from afar and when you see a gap, throw yourself in, Time will be shortly before they come back to attack you so do not waste precious time.
After the battle, go to the next checkpoint to save Jazz. The first thing you will notice in this area will be that the physical attacks directed at the enemies will be totally useless, the only way to beat them is to throw a large object at them to knock them down and at the same time make Ironhide run towards the enemy and to hit.
To do this, use the pieces of the yard or the gray crates at the back of the place. Normal cars won't do too much damage to him so avoid them, after launching him about four times the mission will end.
Chapter 3: The Flight of Bumblebee
Objective: Chase The Helicopter
Bumblebee will be in trouble, he has been captured and is about to be thrown by a Helicopter while attempting to rescue the Yellow Autobot. Simple mission, look at the helicopter icon on the map and to finish the task you will have to use Optimus and go around the city chasing the helicopter and your friend.
If the Autobot symbol goes out of the circle around the helicopter a timer will appear, if you can't get back under the helicopter in that time the mission will end. Optimus is the best of the Autobots for this Mission, he will destroy the enemy Barricades without problems even if a little slower than the others.
Sometimes the helicopter will fly over buildings and you will either have to drive around the building or transform and climb it. Do the second one which is much better and then go back down and continue to the end of the mission.
Chapter 4: Heavy Weapons
Objective: Eliminate Shockwave and save the City
The helicopter will escape from the fight with Optimus due to a strange meteorite, it will have to be haunted on the matter. Two new bars will appear on the screen, one will be Shockwave's energy and the other the City damage bar.
In the beginning the enemy will be in Cannon form, take a tree or a light pole and use it against the enemy. When it transforms, continue with melee melee attacks. Optimus will be able to stand up to Shockwave in the power of the blows.
Optimus When you have removed enough energy from the enemy you will have to run to another point of the city and chase him without losing sight of him like the previous mission. Once found, repeat the process by attacking the enemy with close attacks and you will beat him without major problems.
Inside it Tell Hoover
Chapter 1: Breakout
Objective: Destroy the Doors and stop the Security Droids
Bumblebee will be able to escape from Sector 7 and will now have to reach the Control Room to disable the Enemy System. Follow the green arrow on the map to get the Autobot to the Control Room and activate the next mission.
There will be a metal door ahead, you will not be able to destroy it with the shot so use the violent but effective punches to continue. After destroying it there will be a scene with a security droid. Go after him and destroy him before he can trigger the alarm. You will have to shoot him continuously to do him some damage, it will be difficult and you will have to try several times, at the end try to get between the Control System and the Drone in order to prevent him from activating it and you will beat him very easily.
If you make it you will have to quickly run to the initial door that you destroyed. If you get the Timer to 0 before reaching the area marked on the Map, the Mission will end and you will have to start over. After finding the initial door, destroy the next one and chase the Drone that you will find there.
This enemy will take a different path from the first one, run after him again shooting to destroy him and then go back to the door. This time you will have to destroy the four missiles in the Hall. They will be annoying rather than difficult but you will do well to wipe them out. After destroying the door there will be two more Drones to chase that are much simpler than the first and then you are done and you can reach the Control Room.
Chapter 2: Inside the Tunnel
Objective: Destroy the Fans and Escape the Explosion
Optimus wants the Defense Shield to be destroyed so with Bumblebee you will have to go to the icon to start the next mission. Bumblebbe is traveling down the corridor with many explosions around. A one-minute countdown will begin and you must reach the end of the corridor.
The best thing to do here will be good control of the vehicle, speed is not very important. Use your light and heavy weapons to destroy the debris that will prevent you from continuing. Getting to the end will increase the timer by two minutes and then with Bumblebee you have to destroy five fans in the area.
To do this you will have to transform into a Robot, each fan will be at the end of a very long Tunnel. When you get close quickly transform into a Robot and destroy it. After destroying, move away and then return as a car and go to the other Tunnel.
Remember to get away quickly before transforming or you risk exploding with the fan. Each tunnel successfully destroyed by Bumblebee will increase the time you have available while each trip through the tunnel during the explosion will take away a lot of energy bar.
Between journeys, you'll need to quickly grab the energy icons before heading into the next Tunnel. There will also be a health icon in each tunnel next to the fan.
Chapter 3: Race Against Time
Objective: Shoot the Generators before they explode
Another timed mission, they are the worst in the games along with the escort ones in my opinion. There will be five Generators to eliminate and two minutes to reach the goal. Generators are marked on the Map with green circles.
After reaching the point you will see that there will be no Generator, only enemies around there. The Generators will be on top of the well hidden buildings so find the spot to climb up or destroy part of the building to create it yourself.
Once at the top take the Generator and throw it where you want but far away or Bumblebee will be injured. With each Generator destroyed you will have extra time at your disposal so take it easy.
Chapter 4: The Awakening of the Giant
Objective: To make the Allspark safe
There are six vises holding the Allspark in place, move around the Giant Cube and destroy each vise. Your character's weapons are very effective here. Once you have destroyed all of Bumblebee he will have to survive for three minutes.
In the beginning there will be only Robot Discoverers that will attack you, are easy to beat and will leave you with always useful energy. After 30 seconds Megatron will use his weapons to eliminate you. It will be very hard to survive given the power with which Megatron will hit you, use all the energy left by the scorpions to survive.
Always stay on the move and always shoot, the aim will be to avoid as many shots as possible from Megatron and shoot small enemies to recover as much energy as possible. If this is not enough there will also be the fact that if you leave the battle zone a timer will appear and if you do not return in time you will lose.
The Police will also be there to make things difficult for you but if you are always on the move in a couple of tries you should do it.
Final Opposition
Chapter 1: Exterminator
Objective: Destroy the Energon Drones and save Bumblebee
Once again you will use Ironhide to save Bumblebee. Two things to note at the beginning of this mission, the first will be the life bar of Bumblebee, the second is that you will have to defend him. This mission is very simple, you just have to run around the battle zone and shoot the one that moves.
There will be so many scorpions nearby that it is impossible not to hit them. Bumblebee will never really be in danger.
Chapter 2: Hostile Skies
Objective: Land Starscream and Defeat him
There is going to be an explosion that Jazz needs to investigate. The mission will begin and you will have to understand that Jazz will not be able to fly while the enemy is so first you will have to hit him with your weapons to make him transform. Once brought to the ground use the melee attacks and grab any object in sight to hit the enemy.
Watch out for when he fires his bursts, throw an object at him to interrupt him and then go at him. When it seems that things are going well and Starscream is ready for defeat he will join the Balckout battle. As for the first enemy you will have to make him change shape to hit him.
Run around him and then throw something at him, remember that his most dangerous weapon will be the propeller so be careful. Hit him closely and when this part seems to have ended victoriously a new battle will begin. Here both enemies will attack you and this time they will have energy bars.
The key to victory will be to isolate one of the two and hit him with close-range attacks. You will see that if you shoot them the enemies will stop fighting to defend themselves with the Shields. When Starscream and Blackout load together, try not to get caught in the middle or there will be trouble.
Shoot one to stop him and then attack the other. When you see your energy bar too low, go get the hearts scattered around the area. The advice will be to focus on Blackout and take it out as soon as possible. If you beat the other Blackout first it will transform and recover all the energy.
Usually Starscream will take off leaving only his colleague, this will be the moment to focus on him and take him out and then dedicate yourself to the other. It will be difficult but you should do it.
Chapter 3: The Fall
Objective: Destroy Brawl
The purpose of this mission will be like Ironhide to eliminate Brawl from the face of the Earth. It will not be difficult, you will start one on one, at the beginning of the battle stay close and hit him with your powerful punches. Brawl won't do much to avoid your shots so you won't have any problems.
When you run out of his gauge, Brawl will flee the battle zone. Defeat the four enemies who came to eliminate you and then you have 45 seconds to get to Brawl's new location. An Autobot symbol will appear on the Map, go there to continue the Mission.
Here some missiles will arrive towards you as you approach Brawl, continue seeing the quantity of hearts that you can find trying to avoid the blows and once you get there, transform into a Robot and attack it closely. Brawl will eventually run away again and summon other enemies to help him.
After killing six enemies, return to Brawl, as always you will have 45 seconds to reach the new battlefield. Always do the same thing and when he leaves again two rather strong enemies will come, kill them mercilessly, first eliminate the one with the charge and then the other.
Eventually go for another race to Brael and you will finish the mission by winning for the Autobots.
Chapter 4: Obstruction
Objective: Keep Allspark away from Barricade
Victory is near but the bad guys will try their best to capture the AllSpark. The fight against Barricade is going to be very difficult, when he tries to hit you go back and grab a car or other large object and throw it at him so that you can then approach him and hit him.
Sweep the Barricade bar and you will win. There will be a scene and then you have to get to a race for the power source first. You don't have to race alongside the villain, you just have to get to the green dot on the map first. If you immediately turn left and take this road you will be able to cut it off and reach the green point first.
If you make it there will be another battle here the same as before and then another race but this time the point to reach will be much more difficult. Take my advice, transform and go straight to the next battle zone without engaging in a hard-to-win driving race.
Beat him one last time to complete the mission and save the AllSpark. The only problem is Megatron coming and wiping out Bumblebee.
One will win, one will lose
Immediately after winning the last Mission, Optimus Prime will appear for a battle against Megatron. The first thing you need to know is that you won't have any health icons in the area. The only way to get more energy will be to hit military helicopters.
Megatron will fly leaving bombs towards you. Stand on one of the sides to avoid his blows and after the third blow you will approach Megatron who will be knocked down and in this phase you will have to be careful of his only dangerous blow, the Charge.
Take a pole and when Megatron stops pull the pole towards him. After Optimus's words there will be a bar above the enemy that you will have to quickly get to zero. Megatron will fly again, repeat the process and when he lands again he will throw a sphere with a chain at you.
You will then have to stay away from him and throw whatever object you come across to interrupt his attack. When Megatron's guard drops, hit him until he flies away again. There will be two more times where he will fly the enemy and a third attack towards you.
This time he will use a beam of fire towards you, use the usual system of throwing objects at him to stop his attack and then hit him, he will escape once again. Now avoid the last attacks and when he comes down again he will use all three attacks, hit him for the last time to destroy him and finish the game.
Soccent Military Base
Chapter 1: Sandstorm
Objective: Destroy the buildings and the Air Base
You will have with Blackout 3 minutes and 30 seconds to destroy the base. When the mission starts there will be a Timer and a damage bar that will appear. To make it go up you will have to go around the base destroying all the buildings until the bar reaches 100%.
Chapter 2: Broken Communication
Objective: Pine off the Communications Trucks before the time runs out
Blackout will send Scorponok out to destroy Communications Trucks. Good character this Scorponok, if you press Triangle you will end up in the sand and you can move very quickly. When you find a Truck you will have to destroy it with its most powerful weapons, normal attacks will fail.
The Mission will be timed, you will start with 2 minutes and more time will be added each time you destroy an objective. Do not waste time but dedicate yourself only to the Trucks since the attacks you will receive will not give you any problems.
Chapter 3: Search and Destroy
Objective: Destroy the communication stations and download the data.
Blackout needs some information hidden in a Base. They are divided into five parts within the Communication Stations. Follow the yellow arrows on the Map to arrive in five distinct areas. There will be many buildings in each zone to be destroyed and one of them will become a green dot.
This indicates that the Data has been found, go there and take the green box that will be found there after the translation. Now free yourself from the box by pulling it and trying not to blow it up too close so as not to damage you. Throughout the mission there will be Military Helicopters attacking you, attack them if you need energy.
Chapter 4: Fire in the Sky
Objective: Destroy all the Jets
It will be a great fight. Blackout will have six minutes to destroy 20 Air Force jets. It won't be very difficult given the high number of enemies that will attack you. There will be so many that it will be enough to shoot at random to make a killing.
Better to use weak rapid fire than more powerful because speed will be everything. As the number of enemies decreases start aiming more carefully, they are faster than you. Use the Nitro to increase the speed and bring it to your advantage.
The Key to the Mission will be good aiming and the ability to maneuver Blackout in its Helicopter form.
Autobot a Cybertron
This is an Extra Level that you will get after finishing the Missions with the Autobots. Here you will have to destroy 35 Decepticons to finish the level. You will find a lot of energy icons here so you won't have any major problems, it will just take you some time away.
The Hunt for Sam Witwicky
Chapter 1: Sandstorm
Objective: Destroy the buildings and the Air Base
You will have with Blackout 3 minutes and 30 seconds to destroy the base. When the mission starts there will be a Timer and a damage bar that will appear. To make it go up you will have to go around the base destroying all the buildings until the bar reaches 100%.
Chapter 2: Broken Communication
Objective: Pine off the Communications Trucks before the time runs out
Blackout will send Scorponok out to destroy Communications Trucks. Good character this Scorponok, if you press Triangle you will end up in the sand and you can move very quickly. When you find a Truck you will have to destroy it with its most powerful weapons, normal attacks will fail.
The Mission will be timed, you will start with 2 minutes and more time will be added each time you destroy an objective. Do not waste time but dedicate yourself only to the Trucks since the attacks you will receive will not give you any problems.

Gathering of Forces
Chapter 1: Clean Sky
Objective: Destroy the Radio Towers
For this Mission the Map will be disabled. There will be Static Interference that will disturb the Communication. Consequently, the Communication Areas will not appear on the Map but if you approach some Towers, red arrows will appear indicating the position of the five Towers.
It will be easy to land and destroy the Towers by first flying over them and then hitting them. When all five are gone you can go to the next area and you will only have 45 seconds to find it. It will be easy to find the Towers (shown as six satellite disks) near the ground where Starscream will fly.
During the destruction of the Towers an Autobot could arrive, ignore it and stay fixed on the target. Destroy the five sets of Towers to finish the Mission.
Chapter 2: The Dark Savior
Objective: Destroy the vehicles chasing Bonecrusher
Bonecrusher appears to have encountered some resistance. Starscream will help him, you will find yourself to the right of your ally and this is a Mission in which you will act as an escort. You will need to be able to keep Bonecrusher alive until the main destination.
There will be no need to fly in this Mission, it will be much easier to stay close to Bonecrusher as he moves. It will start in a difficult way, with electrical rays emitting from structures on the earth.
Destroy everything and Bonecrisher will transform and go away.
Follow him to the next area by shooting in front of him. The covering fire will clear the path of any obstacles and start the next set of structures that will create an electrical obstacle. An Autobot will try to disrupt the process but you don't really need to worry. Keep him at a distance by shooting him while concentrating to get Bonecrusher to his destination.
Chapter 3: Fireworks
Objective: Destroy all the Jets and take all the debris
There will be 10 Military Jets that Starscream will not only have to destroy but also recover their wreckage. Unfortunately, you only have six minutes to complete the mission (don't worry too much, that's a lot of time). Once you destroy a Jet a green dot will appear on the map indicating the wreckage left by the plane.
Move there to get them to add a point to your tally. It seems a lot easier to destroy all the Jets first and then devote yourself to picking up the debris than trying to do a mixed and time-consuming thing.
Be careful when you throw the debris to see if you throw them very far otherwise they could very well damage you if they explode. Destroy everything to proceed to the next mission.
Chapter 4: Path of War
Objective: Destroy the vehicles that will attack Brawl and Bonecrusher
This Mission will be very similar to the one you escorted Bonecrusher to except this time it won't be just the two of you. Brawl will need your help and there will always be those electrical machines to stop the two Decepticons from running.
The problem in this mission will be that both characters must arrive safely at their destination, destroy all electrical equipment in order to proceed. Transform quickly and fly past the other ally and then repeat the entire procedure until Bonecrusher and Brawl are safe.
The City of Machines
Chapter 1: Nowhere to Run
Objective: Eliminate Jazz
There will be three phases in this battle. Barricade's goal will be to destroy Jazz. The first phase will be just a punch contest, get close to him and throw your hands as hard as you can. There will be no defensive strategy, just attack like crazy until he transforms and drives away from you.
During the next phase of the battle, it will not be enough for you to chase Jazz through the city. Barricade will have to decrease Jazz's energy enough to make him transform again and initiate the third and final phase of the fight. Keep it steady under fire and if you manage to get past it it will be done, block yourself and start hitting it from Robot to finish immediately.
It will transform again and you can finish it off with similar attacks at the start of the Mission.
Chapter 2: Energon Overload
Objective: Destroy the Energon Drones
Scorponok will be the character in charge of eliminating the Drones created by the presence of the Allspark. This Mission has no strategy but you will only have to destroy each enemy as quickly as possible to not see others created.
Remember Scorponok's ability to go underground for quick moves. Keep moving towards the red dots on the Map to destroy all the enemies and finish the Mission.
Chapter 3: The Giant Will Fall
Objective: To beat Ironhide
You will be using Blackout in this Mission. All that separates you from getting your hands on Allspark will be the mythical Ironhide. Even though Blackout is really strong, the difficulty in fighting Ironhide will be very high and you will probably have to re-do the Mission more than once.
You will see Ironhide in the distance, don't worry about him at first, he will simply be invincible to your attacks. Focus on the smaller Autobots that will be there. When you have beaten them, an energy bar will appear above Ironhide. Now you will face it directly with him, Ironhide will run charging around the screen and you will have to avoid him.
Wait for him to stop to attack him and don't stop hitting him closely until you notice his energy bar disappears or a blue light appears near him. That light will indicate that he is about to make a very powerful attack.
To avoid this, hold down the lock button until the attack ends and then get ready for the second wave of Autobots.
Each wave will also have an enemy that is fast and able to dodge your attacks. Eliminate him in the usual way, throw something at him and then hit him. After you have wiped out the small fish it will be time to take care of Ironhide again.
The latest wave will be made up of simple Autobots to be swept away immediately, even if you don't underestimate their power. If they hit you en masse it will be your end so try to get away and hit them from afar, three hits each will be enough.
Move constantly for another shot at Ironhide. The next wave will be all about fast Autobots and it will be trouble. Stay on the move because besides them you will be hit by human military means. The key to winning this battle will be this:
1 Stay away from Ironhide when there are more Autobots on the Map.
2 Kill the Autobots to be able to hit Ironhide.
3 Always beware of Autobots with Rotating Chains (there will always be at least one).
4 When fighting Ironhide wait for him to finish his Super Attack.
5 If you see a surge of energy near Ironhide run away.
6 When Autobots appear Charge always give them first priority
7 Repeat from step 1
Chapter 4: Devastation
Objective: Destroy the City and find Optimus Prime
Now it will be time for absolute wickedness. Megatrob's Mission will start with a one minute and thirty second timer and bar. Use melee attacks and weapons to make the most of the destruction possible. When you have done 100% of the damage (from the gauge) in the surrounding areas a message will appear telling you to go to the combat zone.
Transform and move to the Autobot symbol on the Map. There will be a lot of Autobots that Megatron you have to take out. Take out all of them so you can continue and then run to a new area of the city to destroy.
Do this and then head to another area with more Autobots to take out. Do this and then another bar to be filled to 100% to reveal the last battle zone. When you get to the Autobot Symbol on the map you won't have to fight but climb the building to start a scene before the Final Battle.
The Day of the Machines
The battle will begin with Optimus and Megatron in heroic dialogue before the action. Initially charge Optimus head down and use melee attacks. Strike until Optimus' energy drops to zero and then he will run away.
Follow him until the battle message reappears. As you run in pursuit, keep an eye on the direction of the enemy because the Map will be blocked, blocking your view. Defeat the Autobots and then find Optimus within a minute or else you'll lose.
Optimus' direction should be through the Park (where you beat Ironhide) and then left. Join him for another battle, when Optimus runs away more Autobots will arrive. Watch out for the yellow one that you will have to defeat by hitting it with something from afar to make it fall and then grab it and throw it at something.
After three throws the Yellow Autobot should explode and then kill the others and return to Optimus. He takes the road parallel to that of the Park and you will find him on the left. Beat him one more time before you find yourself with a fast Autobot and another Yellow. Beat them and then go again in search of the enemy who will be in the construction site with tables and umbrellas.
Beat him again for more Autobots and then go to the last part of the fight very close to where you are. You will make them the last battle with Optimus slightly faster but nothing more. Beat him to finish the game as Decepticon.
