Today, I finally completed the Halo 4 Campaign on solo Legendary. The problem is, I never received any achievement for completing the campaign at all. I didn’t even receiver Master Chief’s armor for completing it on Legendary. In the Campaign menu, it shows that I have every mission completed on Solo Legendary. Also, I did not receive achievements for completing the missions “Forerunner” and “Infinity”. Does someone know how I may receive the proper rewards for this? Again, it shows that I have all the missions completed on LEGENDARY.
Replay the two missions that you didn’t get achievements for, and then it should work.
My best guess is to do those missions again, if not working try it again in co-op
hope it works and good luck!
Was hoping it didn’t come down to that.
