Unlike practically every other title sending trailers to E3, Dust 514 is a game you can download right now and play, for free, on your PlayStation 3. I’m not sure why you’re watching when you could be doing that.
DUST 514 is a free-to-play shooter which shares a server with CCP’s MMO, EVE Online. EVE Online players can pay DUST 514 teams to achieve various goals, and support them by calling down orbital strikes. The effect on the sprawling sim’s economy has not yet been fully realised.
But the point it, shooting things. Pew pew pew.
