The “Silvertip” achievement on the Windows Phone 8 version of Spartan Assault refuses to unlock for me. I’ve done it nine times now and still no bleep bloop.
Kinda worried here since no one else seems to have a problem with the WP8 version of the game. Any potential fixes to this? Already tried uninstalling and reinstalling, didn’t work.
Hello Donut Fun.
This is the first I’ve heard of this issue. Are you sure that you’re signed in when playing the game? Maybe trying to sign out and back in while playing could help (if that’s possible…I don’t have the WP8.)
Sorry I can’t help more. Sometimes the best resolution to these issues is time, so you may want to wait a week and attempt it later. <:/
Just tried that. Did a complete hard reset for my phone and it still didn’t unlock after I tried it for the eleventh time.
I notice that A for Effort and Extra Credit have not been unlocked on the WP8 yet. I would try to unlock A for Effort and then attempt Silvertip again. If A for Effort doesn’t unlock, then I think it may be a problem with your phone, perhaps a setting may have been toggled that is interfering with your achievement hunting. If this is the case, then Windows Support may be able to help you more than I can. 
Unfortunately, I know that it’s the achievement and not my phone.
When I first attempted to unlock Silvertip and didn’t get it, I then attempted the two Vidmaster achievements and they unlocked completely normally.
Hello Donut Fun,
I dont have Spartan Assault on the Windows Phone, however i do remember a few players stated a problem with regards to Silvertip achievement. After providing them with my SA Achievements guide, a few got it, but most didnt, so the only thing i can suggest is PM Bravo or bs angel. However, follow what Cizlin mentioned, b/c that tends to be everyones mistaken by skipping those two achievements. Attempt and obtain those and once you do re-attempt Silvertip achievement and see if you get it. If it doesnt then contact the two individuals i mentioned.
I have all without problems
