Friends and I have been trying to do this achievement on Halo 3 The Ark without getting in vehicles and it hasn’t been unlocking. Trueachievements is showing that no one has received this achievement since April 21. The new update mat have glitches this achievement and it needs to be addressed.
Yes, it is clear at this point that this achievement has become glitched and unobtainable since the April 21st update. No one on TA has gotten it since Apr 21st and there had been several folks getting it each day up until then.
Can any kind 343 person confirm they are aware of this? And hopefully it gets corrected in a future update.
