Sony just announced during the conference at Gamescom 2011 the upcoming release of Resistance: Burning Skies, a prequel to the Resistance series set at the beginning of the Chimera invasion and pitting an american firefighter against terrible odds.

The game has been said to take full advantage of the twin thumbsticks installed on the Vita, and may indeed be the first FPS that proves to be actually enjoyable on a portable.  You can see a few snapshots of the presentation beyond the cut.
