Uncharted: Drake's Fortune

Depending what weapon you are armed with, as a rule of thumb it usually takes 5 bullets to kill someone. For this trophy you will need to blind shoot an opponent 3 times (do not aim and shoot), then run over and press to launch an attack. If Drake kills them with a single punch, then you have been successful. You will need to do this 5 times in a row and then the trophy will pop. Here are some important factors to consider when attempting this:

• When you have weakened an opponent, you must run up right in front of them and press If you attack them from behind then you efforts will be void, because Drake will perform an melee attack.

• If you were to kill someone through a different way, other than what was described about, then your streak will be dead. Worth noting, that you are allowed to Restart Checkpoint, so if you were to weaken someone with gunfire and run over to deliver a one punch kill. And you then decide to restart checkpoint immediately afterwards, then this will not stop your streak.

• When weakening an opponent with gunfire, difficulty which you are playing under will affect how many bullets that you will need to fire. If you are on Easy then you will only require one bullet to weaken your opponent, if on Hard or Crushing you will need 3 bullets.

Kill 5 Enemies in a Row with a Single Punch after Weakening them with Gunfire Guide
Target the 5 kills in a row on you Hard Mode Playthrough, during Chapter 4: Plane Wreck, just before you climb the rocks beside the waterfall. Jump over the ditch and through the archway, there are two pirates who are walking across, weaken one of them with gunfire and then rush over to finish him off. Due to the difficulty I would not risk trying another one, just play safe and Restart Checkpoint. It will take you just behind the archway, repeat this process until the trophy pops.
