Uncharted: Drake's Fortune

You need to make a single explosion which will result in exactly 3 deaths. Do this 5 times and this hidden trophy will pop. You can cause an explosion through 3 different ways:

• Throwing a grenade

• Shooting a red barrel

• Firing an M79 Grenade Launcher

You do not have to produce the explosions all in one go as the deaths are cumulative and will carry over to your next playthrough. Furthermore, if you were to die then it will still count. Lastly, you know when you have been successful in killing 3 people in one go because Drake will make a little comment such as: 'That is what I am talking about'.

Getting this trophy will also earn you Dyno-Might.

3 Kills with a Single Explosion – 5 Times Guide:
Go to Chapter 7: Out of the Frying Pan and make sure the difficulty is on Easy. You will start the chapter off in a Jeep, with Elena driving and you will be firing the M79. As soon as the Chapter starts, aim to the far right and within the opening 10 seconds you will see some boxes to your right and a group of 3 pirates will come out from behind them. Aim your M79 at the bottom of the crates and the explosion should kill all 3 of them. Do not be disheartened if you don't get this during your first few attempts, it will take some time to know exactly when to fire but the best bit is that if you fail you can simply restart checkpoint and within another 10 seconds you can another bash at it. Lastly it is vital that the difficulty is on Easy because on a harder difficulty you may die before you even fire the M79 at the sweet spot.
