So it's no real surprise that they've announced their Halo-esque first-person shooter, N.O.V.A., for the PlayStation Minis service this morning.
As a PlayStation Mini, the game will be without its multiplayer component, but the campaign will remain in-tact. We've actually got this on the iPhone and it's fine for what it is, but it's completely derivative. Still, if you're after a quick fix of first-person action on your PSP, this might quell your needs.
We'll pass judgement when we see how the controls play out.
