Infinity. Dungeon Deities is a kind of persistent online red-vs-blue dungeon builder slash dungeon crawler with powerups.
And loot and stat leveling now, apparently
During the last alpha session players were split into two teams competing to complete various goals, mostly involving finding things in dungeons built by the opposing team. Completing a dungeon would steal a powerup from the player that built the dungeon. This way, players competed with each other for speed boosts, attack boosts, fireballs, boomerangs, spinning attacks, and heaps of other stuff.
The alpha closed a while back so some bigger changes could be made. Looks to me like we might get more soon
