Just played the opening level twice, once as Point man second as Fettel, it's a nice addition to play as Fettel as they have different strengths, can't help but feel invincible teleporting from person to person with Fettel, but that's not a bad thing, it feels really good.
Graphics are on par with Crysis 2 from what I've seen, as you'd expect from a multiplatform title these days anyway but they're certainly not bad.
Classic Fear enemy AI is back too where you hear them shouting on the radio for support and updating their team of your position etc. Then there's the fast paced gameplay, just great fun to play at a fast pace.
Thumbs up from me so far. I can see a lot of replayability and I look forward to trying co-op. First level took me 32 minutes as Point man and 18 minutes as Fettel, just to give an idea of the length.
