When playing with AIbots in the frostbite multiplayer level I 
found this VERY fun and usful cheat. First set the weapons to 
sniper combat and begin play, go across the twin bridges in the 
area that has the log cabin. Once there sit and wait computer 
players should start running across the bridge, when they do 
shoot the ammo box for an instant kill (the comps will never 
learn)
