Achievements (Halo: Spartan Assault)

There are a total of 27 achievements in Halo: Spartan Assault, which are worth a total of 250 Gamerpoints on a Windows 8 device, 400 on Xbox 360, and 1000 on Xbox One. 5 achievements and 50 Gamerpoints were added with a Title Update in August 29, 2013. Seven new achievements will be released for the Xbox 360 and Xbox One versions, with two achievements being exclusive to the Xbox One.

Trivia
Unlike achievements in every other Halo game, Spartan Assault achievements appear on two different platforms. This results in a "doubling up"; players can unlock the achievements once on a Windows 8 device and again on a Windows Phone 8 device. These achievements are also doubled up on Halo Waypoint. Although this can allow players to boost their gamerscore by unlocking the same achievements twice, it also creates the unfortunate circumstance wherein players looking to unlock every Halo achievement and reach the maximum Career milestone must purchase and play Spartan Assault on both platforms (and for some, purchase the platforms themselves).
