First off-monkey assist as a monkey
its really simple, you go to deathmatch and pick the monkey, dont push x on him, push triangle and go to the monkey assist and it will be on the monkey.
H~I~N~T~his name will not be available, i personally think its pretty tight!

multiplayer monkey screw-up
create a new profile and call it Monkey and do the steps above to make ur frends think ur a normal monkey
H~I~N~T~my frend did this to me and we were on a team and i killed him at least 100 times and we were going to 1k kills~~~hehe

kool car esplosion on multiplayer~-~best in siberia
when ur setting up the level put either proximity mines or remote mines (i prefer prox bcuz the other player can see the detonator in ur hand on ur screen and run away----for remote mines only) throw the mines on the car. later, hopefully soon, ur frend will want to get in the car and it will get all booomy on them----hehe

better things for remote mines on esploding car
follow above directions but put mines on bottom of car when flipped over (shoot with sniper to flip)(remote mines only)

how to not blow up from above cheats
all u do is set a heat seeker in the level and shoot the car----extremely helpful if u have low helth, 1 life left, ppl are shooting at u, and a long way from helth, and need to get health. IT WILL WORK!

how to beat the game extremely easily
complete all levels
