Forgive me banging on about this Kickstarter project, but it really looks like it could offer something a little different (especially for the Vita). Check out the video and you should see it is worth investing in, despite the hefty funding $500K+ goal (hey, if it doesn't reach it, it doesn't cost you anything!).
Renegade Kid has put up around four minutes worth alpha footage, showing off how they aim to generate atmosphere for the game. Who wouldn't like to take a stroll around here, and bang some skulls with that wrench!
