Ahead of the October 27 launch of Halo 5: Guardians, 343 Industries has gone ahead and unveiled all of the achievements that will come alongside the game at launch. In all, there are over 100 achievements to earn, totaling 1000 gamerscore.
As with most games, the achievement list runs the gamut of the regular challenges you'd expect from any good game, along with some you can't miss. For example, there are achievements for completing the 15 missions in Halo 5, and then there are harder challenges like simultaneously destroying 2 cores in Heroic difficulty.
There don't look to be any spoiler-heavy achievement descriptions here, so if you'd like to check out all of them before the game's launch, hit up the source link below.
