I’ve gotten this achievement twice now (painstakingly the second time), once on my Xbox 360 and today on my Xbox One hoping that the second time it would let me register the code on Waypoint and give me my EXP this time, I’ve made sure the code I’ve entered was correct several times, and each time it would show the “LOCKED ACHIEVEMENT” or equivalent error message on 360 Waypoint, is there any fix to this, am I the only one having this issue?
The powered by Mjolnir code is only for the Window 8 and Windows Phone 8 versions of the game. The only code that works for Xbox One/360 versions is Flying Colours.
The Able Spartan, Recruit and Powered by Mjolnir codes WILL NOT WORK with the Xbox console versions of Spartan Assault.
