Here's a thing you might not know about Uncharted 3: Drake's Deception's multiplayer. If you run and gun straight at someone and then melee them, you can punch them to death. In the balls.
In a developer diary posted to the US PS Blog, game designer Robert Cogburn calls this the "Iron Fist".
There's also a look at the brutal stealth and traversal kills, which always reward ninja players with medals, plus some more basic actions like blindfire, aiming, and climbing.
Best to study up buddy - if history is any indication, the multiplayer scene will be crawling in expert approximately thirteen seconds after the game releases exclusively for PlayStation 3 next week. Reviews are glowing.
