Availability: After Completing “A Pact With Rais (Second Half)”
Location: A Safe Zone in the Southwest
Rewards: 5,000 Survivor XP, Blueprint for Zaid's Flares, and a Flares x10
Difficulty: Hard
Zaid is in a Safe Zone in the southwestern portion of the city. Talk to him to begin the quest. He needs to get supplies from a hangar to the north. Walk up there and look for a way into the hangar; it’s not clear at first how to get it.
If you have a Grappling Hook, pull yourself up to the hanging roof on the side of the building and get in from there. Otherwise, go to the hangar to the east instead. Use the metal supports near that building to get onto its lower roof, and leap across that until you can get onto the hangar. The jumps are a bit tricky, so take your time.
Rais’ men are inside the hangar, so bring heavy weaponry. Ranged gear is the best, because these guys have guns. Kill the guards above and then go to the far side of the walkways to get down safely onto the train cars. Kill any Infected that get in your way as you go from car to car. Open their doors and look for the Zinc that you need. It’s all there.
When you have the Zinc, use the doors or the walkways above to get over to the side rooms of the warehouse. The Turpentine is on the floor in there. Get all of it and then return to Zaid.
