SWAT 2

Line of Sight Cheat: 

Type in "los" (you may have to do it a few times) 
when you're in a mission to toggle off the Line of 
Sight. All characters will be visible, even if 
they're not in any of your units' line of sight. 
The problem is if you type it too slow, then your 
terrorist guy surrenders. It also doesn't let you 
perform any actions when the Line of Sight is off,
so you have to type "los" again if you want to 
perform a action other than shooting. This is 
especially fun to do when you're playing as the 
terrorists. Even if all your guys are holed up in 
one area, you can watch SWAT make entry and clear 
the rooms.
