Your fire team spawns in a dark room with your ghosts as your only light source. You have to find a door with a health bar to destroy in order to get to the next room. In the second room you are met with waves of enemies and another door with a yellow health bar to destroy. 3 people are focusing on destroying the door and the other three are focusing on the ads. Once you get into the third room, a boss spawns. Once the boss is killed, you enter the 4th room with three doors. They all have health bars, but only one door leads to the next room. Again waves of enemies spawn. 3 people focus on the doors and 3 on the enemies. In the fifth room, there are four doors. 1 door contains a exotic chest, 1 door contains heavy ammo, 1 door contains special ammo, and the last door leads to the area with the final boss. Final boss has the ability to teleport one person at a time to another room. This room contains a door with a weaker health bar. That person has to destroy the door in order to rejoin the fight. The boss also spawns doors that enemies come out of, and other doors that he uses for cover. Tell me what you think in the comments Edit: per sykevandal, the nightfall modifier is active. Edit2: doors also have either arc, sola, or void shields
