Independent dev 5TH Cell have released Hybrid to XBLA today as the next "Summer of Arcade" installment. Their latest game, a new take on multiplayer shooters, is a far cry from Scribblenauts and Drawn to Life.
The matches are in a 3v3 setup. Players side either one of two factions in the ongoing world war: Paladin or Variant. Fight for global dominance! And, you know, hats.
In Hybrid, the world is split into territories, and when one side wins enough matches to reach a certain number of points (there will be a meter for that), goodies are given out. The whole thing then resets. To eliminate the issue of underpopulation, all players will be shooting each other on just one region-free server. A developer walkthrough goes into a bit more detail on that.
Otherwise, check out the new launch trailer and get downloading. 1200 Microsoft Points is the price.
