Plastic Piranha's Rekoil is coming out at the end of this month. Expect the Windows PC version on January 28 through Steam. The Xbox Live Arcade version is titled Rekoil: Liberator, and that's out January 29.
Each version will run for $14.99, but those that want to pre-order via Steam can get the game for 30% off, bringing the game down to $10.49.
What can you expect? 40 different weapons, seven game modes, ten maps, and five customizable classes. Plus the PC version has modding tools, and more importantly, has a higher chance of a player base and on-going support than what the console version would see.
