Geometry Wars: Retro Evolved

An Xbox Live Arcade game (built for the Xbox 360 system), also part of PGR3.

Blast away at enemies with 360 degrees of movement and targetting (via the dual stick control set-up on the Xbox pad) in this throwback shooter game. Return to the farthest reaches of the galaxy, where hordes of evil, neon shapes await! Green squares evade your fire; purple ones divide into smaller clones. Snake-like lines leave behind a venomous trail, and red circles morph into black holes. Conserve your bombs—they destroy all enemies, but quantities are limited.
