"ONE SHOT, ONE KILL"

Snipe Zakhaev and escape from Chernobyl.

Intel #22: When you're carrying MacMillan out of the building with the attacking dogs, look for another fire escape to your right. Climb the ladder, climb the escape and grab the laptop.

Intel #23: At the end of the mission, you'll fight large swarms of enemies while waiting for a rescue chopper. At some point in the midst of this battle, a double door on the left (if facing the Ferris wheel) will open to unleash a new group of bad guys. It's back in the shadowy, grassy apartment courtyards you came through to get to this area. Be warned - sometimes the door, for whatever reason, doesn't open. Just kill yourself and keep trying until it does.
