A "Simple" but well put together game that blends the mechanics of Left For Dead with the vibes from The Thing. This twin stick shooter keeps things interesting by using xp instead of money for reaching goals, thus allowing you to level up, and gain access to new weapons/equipment. There is also enough story interwoven in each mission to keep it from being a pointless slog with no goal. All in all, a truly fun game to play, even more so if you have a few friends to play it with. Good luck and good hunting!

This is a crazy fun game. AS LONG AS YOU HAVE A PARTY TO PLAY WITH. Chaos, death, friendly fire. 3 friends and 2 random players and we had a blast.
