It is worth 10 Gamerscore on Xbox 360 and Windows systems, and 20 Gamerscore on Xbox One. The achievement is represented by a circle with an arrow pointing counter-clockwise. In the Xbox 360 and Xbox One versions of the game, players must use every single armor ability to unlock the achievement.

Trivia

 * Players must purchase either just the Autosentry or all three purchasable armor abilities (depending on platform) 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 another platform, it will automatically unlock the first time the player uses any armor ability in the Xbox 360 version. In the Xbox One version, players must use every armor ability again.
