FORCED

Left 4 Dead meets Diablo
FORCED is a fast-paced cooperative arena combat game. In it, you work together with your friends to succeed in ever more dangerous trials over a diverse set of arenas. As your team racks up victories, you'll get to level up and customize your skills with the 4 different weapons. If you enjoy fast-paced combat, skill experimentation, and game systems that promote teamwork, then FORCED might be the game for you.

And.... It might be the first game that really includes a player shared avatar. That's the orb and the key innovation of the game, which provides really interesting co-op gameplay.
