If you bought Zero Time Dilemma on PS Vita then you can now play the game (visual novel, really) on your PSTV, providing you are one of the 12 people who still use the abandoned hardware. The latest update was rolled out overnight and makes the game completely compatible with the PlayStation TV system.
It’s a shame that it’s not been done sooner, really, but we suppose every addition to the PSTV’s library is welcome. We’re still waiting on more games to be made compatible – games that really should have been from the get-go. Yes, Sony, we’re looking at WipeOut 2048. Sort it out.
