Dust 514 Neocom is the proposed PS Vita tie-in for Dust 514. It enables players to interact with certain elements of the PS3 game – things like altering weapon loadouts, in-game purchasing and more. While there won't necessarily be any gameplay, developer CCP promises an interactive map of the universe that it hopes to "build upon" further down the road.
"700 solar systems and you can drill down and look at the individual planets," CCP Creative Director Atli Mars Sveinsson said in a PlayStation Blog post. "Over time we'd like you to be able to tinker with those planets and manage their surface infrastructure." To clarify: all of these features will be accessible in the PS3 game; the PS Vita app simply allows you to do these things away from the PS3.
Sveinsson and his colleagues at CCP wouldn't say when the app would be available for PS Vita users, but it's safe to assume it'll launch sometime around Dust 514 later this year.
