Problem with “SIZE IS EVERYTHING” Achievement in Halo 4
-In Crimson DLC Matchmaking, kill 20 enemies with a detached Machine Gun Turret.
Shatter Map (From Crimson DLC)
Watching My Stats in Halo Waypoint
In Shatter map I have 192 kills with a detached Machine Gun Turret
And the Achievement Wont Unlock
After my first 20 kills during 3 different Match the achievement did not unlock
Then I enter in a boosting session and kill 20 in one match and nothing
Things I’ve done:
-Clear Cache
-Delete Halo 4 Folder from the Hard Drive (Including DLC, Updates, etc)
-Delete My Profile
And nothing… just wont Unlock
i dont know what to do… i mean… there is nothing to do from my side
This must fixed from Devs side
Maybe they can contact MS and Unlock that Achievements for me… or something like that
Help? >_<
