I am having trouble earning the “117” achievement on SA for Xbox One. I’ve completed all missions and earned gold stars on all of them, and still no luck. My achievement progress shows 100% for the specific achievement, and it hasn’t popped. Yes, I am playing on the same console I bought the game on, and yes, I do own the game on Windows 8 as well. Can anyone help?
This is a bug in the Xbox One achievement system, not in Spartan Assault. I’ve heard of it happening with several different games. See for example this thread about Ryse. The achievement should unlock itself automatically in a day or so. I don’t think you’ll see a notification. You’ll just check again and see that it’s unlocked (hopefully).
I see…
Well then, I hope it shows up soon. If it doesn’t, is there anything I can do?
Sorry, I don’t know of anything you can do. Fortunately, everyone I’ve communicated with on this issue has said they eventually got the unlock, so I’m hopeful for you.
Just popped back in to say it did in fact, unlock. I turned off my console and left for a few hours, came back and I had it. Weird why it does that. Anyhow, got my achievement and I’m happy. Hahaha.
Thanks for the help. 
Happy to hear you’re sorted! Thanks for the help MathGuy42!
