Hi Misters and misses.
So as the title of this post explain, this achievement stay locked since i played on xbox360 of one of my friends;
So, for persuading me to buy the Season Pass and including all extension, i could have a glimse of the news maps, skins and characters of GOW3.
But for playing compfortably on two screens (Not Split), we needed 2xbox 360, so my friend install and download this season pass and extensions on his 2nd xbox.
Firstly, We start the game, i notice who my friend must sign in on 2nd xbox to activate the season pass which allow me to play on.
Secondly, i notice when i sign in with my gamertag, the achievements can not be
unlocked but the maps are available.
So i decide to continue to play without the SEASON PASS, and begin a game in Horde mode.
After playing a lot of waves, and having to play with the SILVERBACK, I complete one of this targets :
Killed 500 locusts with the rockets.
But the problem, it's today. I have the SEASON PASS and this achievement stay locked.
STATS SILVERBACK 2088kills and LEVEL 5
Target : V complete in the list
Please, thanks for help and advices.
Information : Cash system is cleaning, Playerdata and Campain deleted and re-downloaded, (Season pass and horde commandemant Pack too)
