Irrational Games boss Ken Levine has said that he's working with both Sony and Take-Two with a view to getting Bioshock on PS Vita.
"I am literally trying to make a match between the parties," Levine told Kotaku. "They have to agree and it has to be a business deal. I've been trying to do that for a very long time. I'm still very much engaged in that. I can't personally greenlight the thing myself."
Levine also confirmed that he'd spoken to both parties "in the past couple of weeks" regarding the project.
Currently there are no concrete plans for BioShock to arrive on PS Vita, despite Sony announcing that the game would come to the system when the PS Vita was first announced.
