Uncharted: Drake's Fortune

This trophy will pop after your 5th consecutive successful Brutal Combo, if you are unsure on how to perform a Brutal Combo then see Brutal Brawler. This trophy can be quite tricky as you will have to perform 5 combos in a row without a fail. If you die or mess up the sequence, then your count will be reset back to zero. On top of that you will have enemies shooting at you whilst you are in combat. For that reason, I would wait until you have finished your full playthrough and go for this trophy when undertaking your Clean-up run. In doing so, this will allow you to lower the game's difficulty to Easy. Attempting this on Hard or Crushing can be challenging as well as costing you a lot of your time.

Five Consecutive Brutal Combos Guide:
Chapter Select the 1st chapter and make sure the difficulty mode is on Easy. Kill the first wave of pirates who circle around your boat then during the following waves the pirates will start boarding your boat, this is when you start performing brutal combos. You have around 8 enemies who will board the boat so there is a margin for error but not much. If you do mess it up then just restart the Chapter.
