To Kills the boss, just stay at the back, hang out relax, and wait for the boss to kill the others
then when he's on the last person, STRIKE!
I had a massive army, I had so much green I couldnt even see the background were my troops were.
omg, easy! just get all the modifications and upgrades for the grenade launcher nad bam, one shot kill anything, and its explosion radius is HUGE, i also recommend that you buy 2-3! sniper men, and upgrade your sniper(makes theirs upgraded too) :D easy 1/5 game, a ending would of been nice, for instance, a penguin looks over the bettlfield, and boooooooooooom it explodes and he see's a wave of ice shards flying towards him and cuts him to peices! that would be kewl my fellow gamers.
:P
