Resident Evil Operation Raccoon City Walkthrough: Corruption Part 3

After you have searched the area thoroughly, return to the main room and head through the door all the way at the opposite side of the area. You will meet Nicholai Ginovaef for the first time here. Fans of Resident Evil 3 will remember this character well. After the cutscene ends, head up the stairs, grabbing the Antiviral Spray along the way, and search for ammo on the floor and two piece of Intel to the sides. When you reach the top of the stairs, proceed through the double doors to reach the next room.

This area will be full of zombies. The first thing you should do after opening the double doors is to throw a grenade directly into the crowd of zombies, since they will all be packed together before they see you. The blast should take out most of the enemies in this room. Pick off the rest with your squad. Turn to the right to find another group of zombies waiting in the courtyard for you. Shoot them down as well, grabbing ammo from the refill box by the tree in the middle of the area if you need it. Search the briefcase next to the defiled corpse to find another piece of Intel. Sweep through the thin hallways around the courtyard to find the remaining enemies and kill them. When everyone in the area is dead, head through the two central pillars towards the back of the courtyard. Turn right at the end of the hall, then search the ground for another piece of Intel. Turn around and head into the office to your right to find another piece of Intel on the shelf towards the back of the room, and a First Aid Spray sitting on the table.

Leave this small room and proceed back into the courtyard proper. A group of zombies will leap out from the bathroom to the side. Backpedal away from the door and shoot the zombies, then head into the bathroom to find a Gram Grenade. Leave the bathroom and head to the door marked by the waypoint. Before you open the door, search in the rubble to the left to find the last piece of Intel in the area. Grab it, then proceed through the door with your squad.
