Harry Potter and the Deathly Hallows - Part 1

You will earn this trophy when you complete the game on Hard difficutly. Difficulty trophies do not stack in this game, so you have to play on Hard difficulty to unlock this trophy. I did not find Hard difficulty to be particularly taxing. However, when playing, just make sure that you use cover whenever possible and try to go for headshots on the enemies. This will take them out faster and make Hard difficulty much easier. There may be a few places that you get stuck, but Hard difficulty is pretty much a breeze on this game once you understand the feel of the game.
