Long post on the official blog explains economy, persistent shooter, events, etc.
When playing your FPS title of choice, have you ever wished that there was something more to it beyond your rank, weapon unlocks, your kill/death ratio and leaderboard prominence? Those things are all great – but what if those matches you fought in actually meant something? What if your successes and failures against your opponents impacted the course of events in a vast setting, potentially changed a virtual world and the gameplay experience of thousands of other players? More than that, what if that impact was felt across two separate games – one on PS3 and one on PC/Mac – that share the same sci-fi universe?
DUST 514 is that game.
Some may know CCP as the creator of EVE Online, a sci-fi MMO with an open galactic setting. It’s a game perhaps best known for its sweeping fleet battles involving thousands of players, its dynamic player-driven economy, and for having (and allowing!) espionage and spycraft. We think of EVE as the ultimate sci-fi simulation, and that’s where DUST 514 comes in. It’s a whole new way of experiencing the EVE universe through what we call a “persistent shooter”.
