Nowadays I played U4 for around 3 months in the top competitive scene for team GET+ / GETPOISON (with 5 of its original members from U2 and U3) and had a overall record of 300+ wins and 30 losses on UMG before pretty much retiring as lack of competitive support and a worthwhile game killed the scene.

But, But.... Talby came at me with a knife in the final boss fight. I was all like NO WAY KNIVES DON'T BELONG IN UNCHARTED UNIVERSE. Then i was all like B!tch please, Knives versus hands?! I win 'hand's down' No pun intended. He slashed me, and it hurted. Then he tried to do stabby on me, and i was like NOoooo Get the hell off me, go stab sully instead, but then i disarmed him, and i fell and then he tried to crush Sully with a rock/boulder thing, and i was like B1tch please, i haz a gun now. Bang bang your dead talby, don't bring a knife to gun fight, when i'm unarmed at the begnning. And that's how knives fit in teh uncharted universe.
I doubt ND would put knives in because that would probably push the game towards M territory, I don't think that's where they want Uncharted to go. I'm all for less health, but knives? I dunno.
I don't really play Uncharted 3 much anymore...
