Geometry Wars became freakishly popular in Project Gotham 2 for the Xbox, and has been remade and thrown into the 360 arcade. My review.
Graphics: 4.5/5 I can't help but love these graphics. Sure there is nothing much to look at, but the colors look sweet, the explosions look amazing, and the game looks like fireworks galore. This is one part of the game that really draws you in.
Sound: 4/5 There isn't much to be heard. Crappy menu music is annoying, but actually, the in-game sound isn't too terribly bad. Not the game's high point, but it fits the game's style.
Control: 4.5/5 This is a unique way of playing. You use the left analog stick to move, and the right analog stick to shoot and maneuver fire. Unique, and cool.
Fun: 4.5/5 Geometry Wars is really an excellent game from the 360 Arcade. It only costs 400 MSP, and it is a hell of a lot of fun to play. Online multiplayer would be nice, but you can still upload your scores on Xbox Live. Geometry Wars is hard and certainly has a learning curve, but with the low price it costs and the fact that it is so addicting just makes this a game that shouldn't be missed by anyone with a 360.
