Hospital - Quests - part 2 | Walkthrough S.T.A.L.K.E.R.: CS Guide
Last update: 11 May 2016
Go back to the wooden bridge the same way you came before. Notice that one of your allies is placing an explosive charge on the metal door (screen). Move back and wait for an explosion to occur. That's not all. A second person is going to drop a grenade to the machine gun nest, so you won't have to worry about disabling it yourself.
There's a tunnel to your left and obviously that's where you'll have to go. Once you've arrived to the next area, focus on securing some of the nearby balconies (screen). You should also pay special attention to staircases, because they're going to be guarded by enemy troops. Try eliminating as many enemy units as possible before a helicopter arrives here.
This is going to be a rather typical boss battle. Obviously your objective is to take down the helicopter and you can monitor its state with a health bar located in the upper right corner of the screen. Thankfully, it's a rather easy segment, mostly because the gunship won't use any rockets to hunt you down and it has a weak armor. Make sure that you're using the pillars for cover, keep leaning out for a short period of time and use on your assault rifles to damage the helicopter (screen).
Sadly, a helicopter won't be the only threat you'll have to deal with, because more Monolith units will show up in the area. There's going to be only a few of them. Keep shooting at the helicopter until it catches on fire and explodes (screen). Choose a sniper rifle from your inventory and deal with the remaining Monolith forces before moving on.
Now you'll have to get to an area where the helicopter has crashed. Notice that a new corridor is accessible from here (screen). Head down to a lower level and keep moving forward until you've reached a new staircase. You must proceed to the lower floor. Approach the new room carefully and save your current progress.
Lean out carefully and use a sniper rifle to take down a few of your opponents. Try getting closer to your current destination, but you'll notice a machine gun post in front of you. Move back to the previous corridor quickly. You will have to defend yourself against Monolith soldiers for about one minute. Focus only on those soldiers who are brave (and stupid) enough to approach your position.
Once the time limit has passed, you should notice that Clear Sky forces have begun showing up in the area. Your allies are going to be successful in destroying both machine gun posts. I wouldn't recommend waiting for them to secure this entire area, because it'll take too long and more Monolith units will arrive here in the meantime. Instead, start running forward. You'll have to reach a new corridor (screen). Approach the exit and confirm that you want to travel to the nuclear plant.
