too much to list, i bought the game yesterday and i just finished playing it
-too repetitive
-camera angle sux
-not enough enimies
-too damn easy
-too damn short
-boss is lame
-you get to only play the predator (they should have let us play with humans and aliens as well)
-the whole game is tedious, if they were gonna make this into a psp game they should have just made a good graphic 2d game instead.
overal
* one star for sucking so much ass
i'm gonna sell it asap cuz this game is not worth keeping.
