Dust 514 is going to be a FPS/MMO hybrid game exclusively for the PS3 that will bridge itself with the popular (and notoriously difficult to master) game EVE Online. In Dust 514, you will be playing the part of a freelance Mercenary who can work for various EVE Online Corporations (In Multiplayer), that will help decide how territory is taken for people playing EVE Online. As of now, they are targeting a 64-player-per-battle limit.
I am super psyched for this game, even though I've never gotten into EVE Online. The whole idea that playing a Multi-player match in one game will change things in a completely different game is amazing.
