Atlus and Frozenbyte have announced Trine 2 during E3. The first game’s characters will be coming back for the sequel, with the knight, the rogue and the wizard all coming back for more. Trine 2 will support online 3-person co-op. It’s not currently known what platforms the game will hit, but we do know it will once again be a digitally distributed title and will be released spring 2011. The original was released on the PC and the PSN.
