Game mode: Multiplayer - Big Team Battle (This must be done in matchmaking, not customs)
Map: Fragmentation
Location: There are two caves on the left and right side of the map; The cave doors are triangle forerunner doors laced with red to indicate locked and turn blue when unlocked with a collum to the left of the doors. You can better identify them by looking at the door and pressing
, the caves are named Rock Vault Courtyard & Hex Vault Courtyard.
Solution: Stand at the column & press and hold the action button
to start the hack using your A.I. The hack will take 20 sec to complete so I recommend having a few teammates around as you must remain within 25m for the hack to complete. After the hack the doors will turn from red to blue and open, this is when the achievement pops.
Notes: 1)The door lock has a cooldown of 2 min before it can be hacked again.
2)You do not have to enter the cave just be the one to initiate the hack.
