The best old-school/new-school game yet
Asteroids + music + tons of enemies + acid = Geomettry Wars: Retro Evoled.
Basically, you are this ship, shaped come after you. It's up to you to destory those shapes. The enemies are also all different. The blue one come at you slowly, the green ones come at you fast, but turn away when shot at, the pink ones burst into smaller selves when hit, the black holes follow you and suck you in, etc. Rockin!
Graphics:
Suprising amazing looking. It's like a next-gen-old-school look. Simple, yet complex.
Sound:
Great effects, but music can get repetative. At least it's not terrible music though.
Replay:
Tons. Never gets old my friends. You will play this game for hours upon hours without realizing what you've done with your life.
Overall:
A much better, beefed up verion of Geometry Wars, and it's only $5. Plus, it's actually the best 360 game =P
