All right guys- Destroy All Humans is the shit
It has a great sense of humor, the graphics are decent and you can free roam within each stage to an extent( not quite gta but it works). There are cool weapons like the anal probe which shoots like a ray beam and the humans grab their asses and run away until their brains pop out. You can also fly the spaceship and blow up anything you see. The missions are not too hard either and I may actually be finishing this one- I started playing last night and after about 6 hours I am 1/2 way through it i think.
