We first saw the PlayStation 3 build of the game, with improved visuals and great lighting techniques. Both the PS3 and Xbox 360 will have drop-in online co-op, much like their current offline co-op mode. So now your South African BFF can be invited to join you halfway through the Battle of Hoth.
Unique to the PS3 version are motion controls using the Sixaxis pad. We were shown one space battle scene over a Star Destroy where the controls were used to maneuver a TIE Defender. Given the graphical details, we actually forgot for a moment that this was a LEGO game.
