1.) Have all players stand still on the blue cracks for approximately 20 seconds. You will be teleported to an alternate version of the Danu tower.
2.) All players will have to survive an onslaught of Gas Zombies. To progress, you must shoot the 3 orange pods until they explode. Once all are destroyed you will be returned to the main map.
You will receive a max ammo after each pod is destroyed.
