Grand Theft Auto IV Walkthrough

The first thing you have to do is breach the old hospital itself. There are two thugs outside, and they won't see you until you get really close to them or begin shooting. An option here is to take them both out with the sniper rifle, but that's not necessary. Once you've eliminated them, the guys inside the building will be alerted to your presence, however. Approach the building via the hole in the fence (there's barbed wire on the fence making climbing it an impossibility), and use the open windows to take out the rest of the foes in the initial room. There should only be three -- two of them hold heightened positions on the left side, so be especially mindful of them.

Clearing out this place is surprisingly easy (but don't worry, there's more to be done). The cover system works well, if you care to employ it, especially down the long corridor leading to the far end of the structure. We found that a great technique here to employ is to chuck grenades down the hallway. Do so at different angles so that you clear the entire hallway with a few deadly explosions. If you don't have grenades from previous missions, then you won't be able to do this, however. Then, walk around and clear the rest of the enemies, keeping an eye on the red dots on your HUD that represent any survivors. Be sure to grab their weapons and money when they're dead, and then seek out the bag of cocaine represented by a turquoise dot on the HUD when everyone is eliminated.
