The achievements in Halo: Reach are extremely easy. They are split between Campaign, Firefight, and Multiplayer Matchmaking. The Campaign achievements consist of beating each level, beating the game on certain difficulties, and a level specific achievements. The only difficult one here is beating the game by yourself on legendary. The firefight achievements can easily be obtained by creating a custom match and just playing for half an hour. The multiplayer matchmaking consists of extremely easy achievements and then a few rank based ones for getting a higher rank. Overall the achievement list is extremely easy, and quite disappointing compared to the achievements of earlier installments of the franchise.
