Sony has released a launch trailer for their charming and rather good PS Vita game Gravity Rush. The game sees gamers take control of Kat and her magical, erm, cat who gives her the ability to defy gravity. It’s a nifty concept and one that deserves some attention. If you haven’t already, I recommend PS Vita owners download the demo and sample the goods themselves. We’ll have our review up in the coming days. Stay tuned.
