Some people are even more dangerous than the outbreak itself. You can’t let Rais survive this. Find him now.
Confront Rais
Head for the sewers and return to the slums where all this began. Rais is there waiting for you. There aren’t any attacks or traps in the sewers (except for some Biters), so it’s a faster run than it was to get through the first time.
Enter the building that’s shown on your map and make sure that all of your weapons and items and repaired and armed correctly. Don’t use your Grappling Hook for the area ahead (because it won’t work). Instead, equip thrown weapons and as many Firecrackers as you can handle.
Nothing goes awry until you reach the floor in question. The waypoint gets you right there, and then, shockingly, it’s not exactly what you expected. Fleeing would make some sense right now.
After Rais triggers his event, sprint to the right side of the room and jump off the ledge so that you land on the garbage bags below without taking damage. Run through that yard and down toward the lower area ahead of you. Make for the pipe at the bottom while staying one step ahead of your pursuers.
Go ahead and drop down the hole in the middle of the pipe. It sends you into the sewers, but that’s about your only chance. Kill the Screamer below and resume your sprint. A waypoint marks your destination, so use that as your guide.
Follow the tunnels without making any substantial engagements with the Infected. There are far too many to kill. Throw an occasional Firecracker to keep them from swarming you. Dodge aside or use Vault if anything gets in your way.
You eventually reach a set of beams that must be carefully traversed. Line up your run before you get there to avoid maneuvering much once you’re already running across them. Going over this tough spot may stop some of the Infected that were behind you, but the pressure from the sides is still on. They’re coming at you from everywhere! Slide under the barricades to get a small respite and use times like this to grab a Medkit and restore your health if you’ve taken any damage. Use ziplines during the downward sloped area to get a bunch of fun XP while kicking Biters all over the place.
There are minor jumping areas to pass as you proceed. The next one has you go along the right side and then leap to the left. The one after that has two sets of pipes you must jump between before getting up a level. Perform these as best you can. If you fail, you must restart the entire sewer portion of the run.
The next section ends with a pit and some pipes. Run up the initial pipes and jump to reach the ones that are too far away to step onto. Keep running at the top, and make a long jump to reach a ladder at the end of the passage.
Climb to the top of the tunnel and work your way out of the sewers. This drops you into the good old arena. Look for a container to the right of it that’s leaning against the wall. Get onto it and use it to reach a set of iron bars above. Climb those, then turn around and jump to the bars behind you. Go back and forth like this to reach the lip of the arena and pull yourself out of it.
Get into the red elevator ahead and use it to reach the top of the building. Wade through the mass of Biters on your way to the waypoint, then talk to the man on the floor above. He provides a few tips for avoiding another trap.
Go outside and jump off of the ledge that’s coming up. You can reach a safe landing spot by a crane. It doesn’t have many Infected on it, so you have almost safe passage to the other building. Go across the crane and kick off the lonely Biter on the other end.
Jump over to the building nearby and run through the room in front of Kyle. The stairs are directly across from the window where you enter, although they lead up only a single flight. At the top, go out onto the walkway and jump onto some scaffolding. Use a Firecracker to distract any Biters that are too close for comfort, or kill a group of them as you see fit.
The scaffolding gets you over into another room with a heavy Infected presence. Again, throw a Firecracker to distract them if you’re trying to race through. Or, clear out the Biters and Virals in front so that you have room to kill the Goon that’s bringing up the rear. Amusingly, if you run past group and leap onto the scaffolding behind them, your enemies kill themselves trying to chase you. They fall to their deaths trying to get onto the scaffolding!
Your next waypoint is several jumps away. Ready a gun before you begin, then leap between the cement beams on the side of the building. Push harder than you think for each jump because you’re not getting a running start for most of them, and coming up short equals a fast death.
Back in the building, you’re greeted with screams from a Gas Tank. He’s charging right at you; that cannot be right. If he gets close enough, he detonates and takes you with him. Use your firearm to shoot the Gas Tank at range and kill him safely.
There’s a Bomber not far behind him. Trigger him and dodge behind either walls or the pallets on the ground until that one explodes, then look for the elevator shaft ahead. Get in there before you’re bogged down in fighting, and start to climb. The shaft gets you to the top fairly quickly, where you can then use ladders for the remainder of the trip up.
Get to the top and pull yourself onto another crane to return to the main building. Sprint all the way across the arm and jump onto the wall ahead. The crane starts to collapse, and if you wait for even a moment you’re going to miss your chance and go down with the whole thing.
Pull yourself up the wall until you can’t go any higher and then look for a grey ledge to your left. Jump over there and turn the corner to look at the next section of this “walkway.” It’s not really meant to be used as a way across the building, but beggars can’t be choosers. Use the yellow railing to reach the far side of the structure, then step back onto a ledge.
Run forward and climb the next wall to reach a higher floor. Jump carefully onto the exposed cement platform in front of you, and then take another walk on a yellow railing to proceed.
Climb up through the next couple areas using construction equipment. Rais is up top. There are several quicktime events that you need to complete, but we won’t spoil what happens. Just be ready to hold the first button and tap the buttons shown in the subsequent events.
The end is in site! Good luck.
