Tomb Raider: Anniversary

Before you start the game make sure you change the difficulty setting to hardcore.

The hardcore difficulty setting is available to choose from the very beginning, therefore to reduce to the number of playthroughs needed, I recommend you change the difficulty to hardcore straight away.

All you need to do now is beat the game. Nothing much changes from the easiest difficulty to the hardest. The enemies will be a little bit harder and Lara will take alot more damage than usual, but altogether the difficulty is still incredibly easy.

IMPORTANT NOTE:

It has been said that if you try and complete a time trial before completing the whole game then your difficulty is set back to medium. Therefore if you were going through the game on hardcore you will no longer get this trophy, because technically you will end up finishing it on medium. To make sure this doesn't happen just complete the game in its entirety first before doing any time trials.
