So close to perfect!
I have to be honest here, This game is awsome no way around it... BUUUTTT, like many other reviews said, the game could use some improvments. First, the attacking in the game was kinda hard to get used to and control. I'm not even sure if there is combos or not, if there is than i complete missed it through out the whole campaign mode. If there is combo's then there should be a tutorial on how to use them. Also if there is no combos... then you really need them. It gets old using what seemed to be just a punch and a kick. If you could some how make it so depending on what kind of feet and hand the character has that character will do it on unique moves.
Second, the weapons were awsome and all... but the fact that most of them were one hit kills really pissed me off somtimes. escpesially the on universe city... omg that atom bomb... @#&!. Between that item popping up the most and the computer player being 1337 was just very aggrivating. So in the end, make most the weapons just high damage weapons or somthing. It would also be nice if there was a way to block the atom bomb... but that may have been your point of having it in there game (everyone dies no matter what).
Third, there was some upgrade like item that woudl make you faster or jump higher... im not quite sure what they did but one of them seemed to kill me cause id be to fast or somthing and i would just go right of the edge, maybe its me having the lact of ability in your game but I would be to surprised if other could agree on that.
Any how AWSOME game, Hope to see the sequal! And I hope to see multiplayer and some small improvments! Good Luck.
