The game saw protagonist Nathan Drake return but in a bigger adventure that took him across the world, rather than restricting him to one island. If the enemy doesn't see sneaking on him from behind or his side, then he is able to not cry in the market to alert his comrades nor is he going to have a very chance to fireside his weapon. One final gripe - the very last third of the game is 100% carbon copied through the previous game - I'll stay away from the spoilers, however, if you've played Uncharted 2, you know what I mean if you see it.
