Lego Indiana Jones 2: The Adventure Continues

Lego Indiana Jones 2: The Adventure Continues lets you wreck brick-havoc across the fourth movie's scenes, but it's also a completely new take on the previous trilogy. This title brings a lot of improvements and changes to the Lego series: the more open level branching, finally subtle use of next-gen FX and level editor all contribute to the renewing of the Lego/movie super-franchise, just in time for the upcoming Lego Harry Potter game. The new free-form gameplay and vast hub zones will have you begging for a minimap though.

Zombie Driver

Zombie Driver is a 3D top-down driving game. You'll have to dodge, maul or shoot through zombie hordes all around the city to reach trapped survivors and bring them back to safety. The game consists of a single 17-mission campaign, but you're free to drive anywhere and kill as many zombies as you can for additional money. The Ogre engine allied with software PhysX allow for nicely detailed dismemberfest and fence crashing.

Torchlight

Torchlight is a 3D singleplayer hack-n-slash. Despite the low-gore atmosphere, post-WoW look/pets/steampunk weaponry, and Titan Quest-like skill management and two-handed combat, the gameplay of Torchlight is as close to good old Diablo's as it gets.

Overlord II

Big Evil returns for more third-person wielding and minion-commanding action. New features in Overlord 2 include an extra layer of next-gen eye candy, mounts (allowing your multi-colored horde to access otherwise out-of-reach places), a refined magic system and more - but the core of the game remains the same : lead your horde to bend everything and everyone to your will, then get back home and buy new furniture.
