Operation Spacehog is a typical arcade space-shooter type game. It has powerups, fast-paced gameplay, pulse-increasing music and graphics that are bound to please.
The main theme of the game is that aliens are attacking Earth and you are the only one worthy enough to protect it by destroying the evil invaders. Not a very complicated background, but hey, it works.
My main gripe with this game is that it has been done before many times and is basically almost a Space-Invaders clone to me. However, it does indeed provide excellent gameplay, if not something that feels like I have played before, which is why it garners a 80% rating.
