Embarkment
Upon transmat back to The Leviathan, players will approach the first door seen. Now unlocked, it will open and allow the fireteam to venture into a deeper segment of the ship. As they progress, player will have to jump through holes in a giant gear blocking their path. Failure to jump through one of the holes at the right time will result in death. Once they pass this, they will leap even deeper into the ship and land in the ship's reactor.

Reactor Room
To proceed through the reactor, players will have to cross a series of platforms that rise out of the coolant. Only one player can be on any single platform at a time. If more than on player is one one, it will sink into the coolant, resulting in death unless they can reach an unoccupied platform or return to the nearest waypoint. Once the first platform has a Guardian on it, the next platform will rise and the leading player can jump onto that one while another jumps onto the previous platform. The cycle will be repeated until the platforms lead to a waypoint. along the way, Psions will appear and try snipe at you. It is best to simply dodge in order to avoid missing your window to reach the next platform. Note that there is a time limit to cross the platforms: if time runs out, the reactors temperature will rise, retracting all of the platforms and wiping everyone on them. However, the players will no longer have to jump on the platforms in any order, and more than one player can occupy a platform. If enough players reach the waypoint before the platforms sink, they will be allowed to proceed when any dead players revive. Should a player respawn at the beginning, the platforms will all rise allowing for easy access. Once the waypoint is reached, a squad of Loyalist must be defeated before proceeding to the next set of platforms. The platforms form a different path with progression, and the time limit to complete the path is shortened as well.

Once the team makes it past the four series of platforms, they will have to fend off several waves of Loyalists that appear on both sides of what becomes the battlefield. The team must dispatch each wave until four Collosi arrive. Once they are all felled, Calus will call off the attack and open a hatch leading deeper into the ship. At that point, the lair's first loot chest will appear. Once your rewards are collected, you can enter the hatch to the next stages.
