This achievement requires the coordination of at least two players.

On ONI: Sword Base, have one player stand southeast of the COMM Array atop a mound of rocks beside the coast (See image). An ‘open door’ prompt will indicate the correct place. Do not press it yet.




Have the second player stand atop a rock jutting towards the West near the AA Cannon (See image). An ‘open door’ prompt will indicate the correct place.


When both players are in position, simultaneously active the prompt, the objective will change, and you will be teleported to the Easter Egg. The achievement will also unlock.
