Are you not bored of saving humans, seriously... Why saving earth when you can DESTROY ALL HUMANS!!
DAH is a game where humans are the enemies. The game has unique characteristics that help it be a really good game, for ex: the ANAL PROBE, you porpably have heard of it in other reviews, you can shoot it at humans or like the Furons (the invaders) call us... MOKEYS!!. Other ex can be reading peoples thoughts, sometimes they say some crazy, funny stuff that will make you laff like hell, they rarely get reapeated. The game starts at a farm and you get to kill lots of cows with your mental powers, then at the second city you kidnap a woman. there are about seven cities to go and mess up with people, its like gta's freestyle. In the game there are 4 alert levels: warning, police, military and finally the Majestic (majic 12). At the end you will have everything and can do whatever you want!
As i told you, why saving eart and humans when you can DESTROY ALL HUMANS!!!!!
