Last night I while I was playing I was told about a working ‘cheese’ for the zero hour quest. This involves one member of the fire team spamming the director and inventory buttons repeatedly during loading in, preventing them from spawning into the quest. The other two fire team members are then able to complete the quest without a timer active.
If possible it would be great to see this issue fixed as I feel like it is devaluing others achievements who got the weapon the legit way. This is currently an issue on Xbox One I am unsure about other platforms.
