I bought Spartan Assault for the Halo 4 unlockables, and I’ve unlocked the achievements “Recruit” and “Prodigy”, but I can’t unlock the “Powered by MJOLNIR” achievement.
I’ve already used the following.
M.A1 - Regen Field
M.A3 - Sprint
M.B1 - Stun Blast
M.B4 - Hologram
M.C3 - Active Camo
M.D2 - Hardlight Shield
Bought with exp - Autosentry
I see from your Service Record and achievements that you are playing the Xbox 360 version. The different platforms have some different behaviors, so it’s helpful to include this.
For the Xbox 360 and Xbox One, Seeker Drone and Overshield are also required, as described in this TrueAchievements solution.
However, the codes you found will not work for Xbox 360. Recruit, Prodigy, and Able Spartan codes are only for Windows 8 and WP8. Fortunately, the Flying Colors code should work for you.
I’m curious where you found the codes you are trying to use. Could you post the website address? This question comes up a lot, and it would be great to be able to ask the owner of the post or site to edit it, making it clear which codes go with which versions. Thanks.
Thank you! I’ve asked several times for such a URL and you are the first to post one. I’ve tweeted Naked Eli, asking him to please annotate his code videos so others will know that Recruit, Prodigy, and Able Spartan codes are only for Windows 8 and WP8.
