We recommend using a Speed Booster to maximize execution speed.
Talk to Rahim, then continue towards the overpass, kill the Biter near the bus, turn the body in front of you (Omar), then continue towards the trains, killing all the Biter near the car.

the pit
Head to the Rais complex to retrieve Dr. Zere. Unfortunately, as soon as you arrive in the area, you will notice that it is not possible to proceed through the front area. You will therefore have to find another way to enter. Swerve to the right, locating the red pickup truck that crashed into the wall. You will then have to climb the scaffolding, reaching its top. At the top, jump to the right, locating three opponents in the area below. Kill them and proceed forward, also trying to locate the ropes in the vicinity. At the roof, you will find four more enemies, two on the right and two on the left - immediately take out the ones on the right, more dangerous than the others. Then locate the hatch, on the right area of the roof.
Use the elevator, then go down the shaft to proceed to the outside. Down the stairs, locate the subject on the left, eliminate him, then always continue forward locating the next enemy near the corridor. At the bottom, another enemy will come out of the doors immediately behind him. So check all the rooms to locate the items and pick them up. Move down, getting rid of two more enemies. When you reach the garage, locate the gun. Locate the room, then go down to the garage, proceeding to the building. Right, proceed upward, throwing yourself to the side as you clear the enemies. Make use of the propane cans, then head towards the van in the center. Turn right and hit the guns, then move forward again, arriving at the room with Zere in it.
After you wake up, you will notice how you have lost all your weapons and you will have to go and retrieve them as they are scattered throughout the arena. Watch out for the Biters and Runners. Jump over the containers and retrieve the Rebar, your strongest weapon. Jump across the container again, making the Runners catch up and hit them as they are running towards you. When there are only 2-3 biters left, go get the propane cans and throw them towards the center of the arena. Killed all the zombies, you will have to deal with the Demolisher. He is equipped with full body armor, which you will have to repeatedly attack to destroy. Only after the pieces of armor have been destroyed can you hit his "flesh". In these moments you will have to pay attention to his charge attack, to be dodged by moving towards one of the two sides. Always try to place the propane cans in the center of the playing area, so that the opponent goes to hit them during one of his charges.
With the Demolisher killed, watch the cutscene. You will therefore have to start running again, it will not be useful for you to continue fighting since the opponents will constantly shoot at you and you will not have the opportunity to "cover" yourself from their shots. Once you exit, you will begin to lose HP, continue forward avoiding the attacks of the Biter. Wait until you reach Brecken, watch the cutscene, retrieve your items and proceed forward to the next level.

Exit the room, letting the wall next to you fall apart and a breaker comes to the area. Avoid staying in this area - you would be forced to fight against an endless stream of Demolitionists, so keep going down to the rubbish on the right. Explore the buildings in the area, talk to Savvy to activate the station, recovering the Keycard to be able to enter without problems.
