So I've been playing Splinter Cell: Conviction on the 360 and am trying to get the Hunter Master achievement in which you have to "Complete all maps in "Hunter" game mode on Realistic difficulty" Hunter Mode means clear the map of enemies. And Realistic difficulty being the hardest difficulty. There are six maps each having about five areas of 8-10 enemies in them. I got to the last area of the last level and realised that I had not changed the difficulty from Normal. I proceeded in cursing out the game.
