Tom Clancy's EndWar

The trophy is similar to the Tour of Duty trophy, but must be played on Expert difficulty. This level of difficulty shouldn't give you any problems if you use the combat triangle correctly. I recommend making a save after every win so that if you fail you can exit to the main menu and load the game before you lose. This trophy is also unlocked for beating the game on Hardcore difficulty. Therefore, if you are confident in your abilities, go straight to the “Ready for Theater of War” trophy.
