YouTube user digitalarts001 has made it possible to run Left 4 Dead with motion controls on the PS Vita, using a custom-build application on the PS Mobile SDK and Remote Desktop. The possibilities with PlayStation Mobile appear to be endless and the video below proves anything is possible on the PS Vita.
The game is streamed from a computer to the PS Vita, allowing the user to use the Vita’s screen and controls to play the game. It’s a bit like Remote Play between the PS3 and PS Vita.
