It gave me the answer to my suspicion of FPSs on the Vita- they are frickin awesome! It also reminded me of how good Resistance is too, they gave it a really good campaign in terms of gameplay as well as the story. And I'm not really one for FPS multiplayer, but this game pulls it off pretty well on a handheld and that's a huge task in itself so my hats off to Sony and Nihilstic for this one.
Overall, though, my favorite part of this game is DEFINITELY the campaign. I like it better than the console-version Resistance storylines lol.
I played a couple matches of multiplayer yesterday and it is pretty fun. The single player campaign is also fun and I like how the game utulips the touch screen. Definitely proves that fps works on the handheld so I expect a flood of them soon lol.
