Microsoft really struck gold when decided to add Xbox Achievements to their games. It may have been seen as a cute gimmick at first, but gamers really took to it. Hunting down achievements added a ton of replay value to games, and comparing Gamerscore turned into a friendly competition between friends. These days, there are people who game solely for the purpose of passing their already monstrous Gamerscore, as well as websites and YouTube channels dedicated to providing tips and tricks on how to unlock some of the harder achievements.
Naturally, some achievements are harder than others. Completing the tutorial or first level is not the same as mowing down the final boss on the most extreme difficultly, using only a rusty fork as your weapon. Game developers quickly upped the ante with a few of the achievements they built into games, forcing anyone with an obsession for gamerscore to face some really tough tasks. Here are some of the hardest Xbox achievements to get.
[Note: This list includes games from both the Xbox 360 and the Xbox One, although some of them are available on both consoles.]
