It was announced today during the CCP Fanfest that DUST 514 closed beta will start in April and that the open beta is targeted a time close to this years e3. The announcement was from the developing team themselves. If you are a fan of MMOFPS then you should keep an eye out for invites to this game.
Dust 514 is uniquely directly linked to an existing MMO, EVE online. This exciting link between the games makes it extremely easy to switch between games without the need to get reinstated with each game.
