Look, all I'll say is that in Batman, you get attacked by a giant shark and you get a button prompt labeled "Beat Down".
You beat down a shark. Debate over.
I haven't played Uncharted 3 yet but the reviews are pretty good so far. Did you play Uncharted 2 or Arkham Asylum? Both games are like those only bigger and better so whichever one you preferred, go with that.
