Lost Planet 2 - $12.62 at Amazon

Amazon has Capcom's Lost Planet 2 on sale for $12.62 with free super saver shipping today.  I haven't played this one myself, but from what I've read it seems to be a pretty solid game, minus a few framerate issues.  Amazon gives it 4 out of 5 stars, while MetaCritic is slightly harsher at 68 / 100.

A decade has passed since the first game, and the face of E.D.N. III has changed dramatically. Terraforming efforts have been successful and the ice has begun to melt, giving way to lush tropical jungles and harsh unforgiving deserts. Players will enter this new environment and follow the exploits of their own customized snow pirate on their quest to seize control of the changing planet. Players will control their heroes across 6 interconnected episodes, creating a truly unique interactive experience that changes depending upon the actions of the players involved. The intense and action packed campaign mode comes with the ability to form teams of up to 4 players online to clear mission objectives with friends. Lost Planet 2 has a huge variety of hardware for players to unleash on unsuspecting enemies. Machine guns, shotguns, rocket launchers, lasers, sniper rifles, grenades and a host of other weapons are scattered across the game. However, Lost Planet 2's biggest weapons come on two legs: the heavily armed and armored robotic Vital Suits return in greater numbers and variety than the first game. There are VS that transform into other vehicles, hold up to three players and some that even take multiple players to operate.
