Play as Niobie and you will start in a room where there is an Agent shooting at you. Ignore the "Don't fight, run'' message. Instead, take out your MPS gun (you can use a pistol). Shoot him and he will dodge the bullets. Get him to dodge all the way to the left or right. At that time, shoot the explosive barrel. It will kill him, and you may pick up his gun.

As Niobe, when Sparks says run, do not fight him (turn on Focus). Run between the two missiles and turn around, then shoot the bio hazard sign. The Agent should fall and lose his gun. Note: Use the shotgun.

After you find tunnel 7R, An agent will chase you. There is a very easy way to kill him. Every so often there will be a tower lit by red lights. On this there are four boxes labeled "Danger: Explosive!". Lure the Agent near one of those boxes, step back, and while in Focus mode, shoot the box in first person mode. This should instantly kill him, and you can take his Desert Eagle.
