Get past lazers (on 1st level):

A little bit before the truck with gasoline
use your night vision glasses to see though
a chain linked gate, shoot the controll box
to open the gate you should see lasers in 
front of you, you can't jump over it or roll
under it or else you either die or loose most
of your life. instead shoot the little box 
where the lazer comes out and it will shut 
off: ...a guard is around the right corner 
so be carful.
