Powered by MJOLNIR

Powered by MJOLNIR is an achievement in Halo: Spartan Assault. It is unlocked by using every armor ability at least once (excluding Overshield and Seeker Drone). It is worth 10 Gamerpoints on Xbox 360 and Windows systems, and 20 Gamerpoints on Xbox One. The achievement is represented by a circle with an arrow pointing counter-clockwise.

Trivia

 * Unlike the Weapon of Choice achievement, which does not require the player to purchase any weapons, players must purchase the Autosentry to unlock the Powered by MJOLNIR achievement. All of the other armor abilities are used at least once as default armor abilities through the course of the campaign.
 * If the player has previously unlocked this achievement on a Windows 8 device, it will automatically unlock the first time the player uses any armor ability in the Xbox 360 version.
