The Clinic

Reward: 15,000 Survivor XP

You’ve staved off disaster, but still must reach Doctor Camden at the clinic in Old town.

Bring Dr. Zere’s Samples to the Clinic

The clinic is a couple minutes away from where you are. Call Dr. Camden to let him know that you’re on your way, then cross Old Town again. There are Infected and Rais’ soldiers around the clinic, so move in quickly to avoid getting bogged down and shot.

Slide under a mostly-closed shutter to get into the main lobby, then immediately attack the two men inside. Hack them to pieces and use the elevator call button in the back of the room.

Wait for the elevator to arrive, get in, and descend into the bowels of the building.

Find a Way to Get to Dr. Camden

The power in this place isn’t working very well, so you don’t have access to much of the facility. Go through the first few rooms, and look for the locker room farther in that has an open grate on the ceiling. Climb into that and crawl through the ventilation shaft. It’s hard to get lost up there, but you sure don’t have much room to maneuver.

Drop into the connecting chamber and keep your weapon out. It doesn’t look like there are any threats in there, but looks can be deceiving. After you deal with any problems, use the computer terminal to unlock the doors in the building.

Slide your card through the reader beside the door out of the room, and open the way back into the corridor. Go toward the next waypoint and don’t get too close to the doors or windows of the rooms you pass. There’s plenty of pounding and screaming going on. The place has probably seen better times.

Camden guides you toward a decontamination area. You get a nice look at it, but the systems won’t work yet. Instead, backtrack to the office area in the previous large hallway. Camden opens the doors for you, but the fighting is all on your shoulders. Kill a couple of Biters and then handle the Gas Tanks that come out, too. Back off and use ranged weapons if you’re worried about detonating their tanks in these confined spaces (something that could easily kill you if you’re in melee range).

Restore Power to the Facility

Unlock the next office and go inside. Most of the Infected are on the floor when you enter, so you can get a few easy kills before they rise. Do that quickly, then finish off anything that’s still moving.

Pull yourself into the shaft above that room. It goes around the long way to get over the main hallway and then across it. When you reach the end, you find a warehouse area with barrels scattered everywhere.

Stay on the shelves while you look at the Biters and Gas Tank down on the floor. They’re surrounded by a toxic fog that you don’t want to play with. Shoot the Gas Tank to blast the mob, then jump down to the boxes and forklift below to kill the Biters without touching the floor.

The red doorway is totally sealed. Hmmm. What about the forklift on the right side of the room? It has a raised load that might be blocking something. Try to lower the load and then see what’s up there. You can get to another shaft and over into the adjoining warehouse through it.

There’s a very large Goon in the darkness below you. Kill him with ranged weapons. It’s wiser than jumping down to fight him with melee attacks. Several Gas Tanks are resting on the floor, and you don’t want to disturb them during a battle. It’s better to snipe the Goon and then assassinate the Gas Tanks before they wake up and attack you.

Go to the forklift that’s blocking the door and use it to lift its load. You can now get back into the primary hallway. Crawl out to it and use your card to open the last side room in the hall. There are three power generators inside. Try to turn all of them on and you get most of what you’re looking for!

Run the Decontamination Process

Retrace your steps back through the warehouses and into the ductwork. There are quite a few tougher Infected in the big hallway, but you don’t need to attack any of them, and they won’t notice you unless you do something crazy or loud. Only fight if you’re looking for extra Power XP.

Get all the way back to the decontamination room you saw before and press the bright red button by the windows.

Allow the process to reach its conclusion, then continue through the chamber when the doors open. Meet Camden and give him the Samples you’ve been carrying. Wish him good luck with his research, and then leave the facility. The security door on your right makes it a fairly short trip out. Return to the elevator, ride up, and make your way outside.

Contact the GRE

Reward: 20,000 Survivor XP

Several radio calls come through after you get outside. Instead of calling the GRE, other things happen and your waypoint changes.
