This is a game I, almost sad to say, looked forward to. It looked decent enough and it was only a couple of bucks (I bought it on sale, by the way). What I got was a rather clunky experience that I only enjoyed with a friend, but not alone. I'll list out my problems below:
Controls: For the most part, the controls responded to my inputs. For some reason, my controls gave out on the third tutorial. It seems as though control of your helicopter freaks out sporadically. However, those times are few and far between, so the controls are alright at best in my opinion.
Game Play: Lackluster. There is no real sense of where you're supposed to aim at the enemies and overall it seems like the one thing I look for in a game, bores me to death. Also, the helicopters you get to chooses from don't even feel different in the slightest.
Powerups: I add this because when an arcade game comes along, there is bound to be powerups found. However, most of the time, I don't know what they do. Some are self-explanitory, but other don't make any sense. If there was a system that told me or at least some kind of instruction, I would be fine with it.
Voice Acting: This is one part of the game I like solely for the reason it sounds like early PS1 english voice dubbing.
Soundtrack: Forgettable. Sometimes non-exsistent.
3/10. This game is a lackluster experience unless you have a friend along. If this was a comepletely single-player experience, it would score lower. All in all, do NOT buy this game.
