Just finished it. I have to say this needs some more choices/strategy. Right now I just mashed buttons without even knowing what I was doing and I won.
There was a bug with the last level. I killed everything but mission did not end. I saved the game and loaded it and then it said that i finished it and it had dialog from the beginning of mission that i did not get.
Well, it seems that you can't replay levels is major turnoff. Well if you buy wrong weapons or want better ones then you are screwed. Seems gameplay wise very stupid decision. I don't why gamedesigners makes it so, it stupid to me.
Well, was the button mashing fun? :D
