Siege Engine

Siege Engines are massive, mobile, ultra-heavy artillery machines that the Devil Splicers use to smash down The Wall. One can be seen in the Wrath of the Machine Raid.

Gameplay
The Siege Engine is a particularly difficult boss fight. It will continuously assault your position on the battlefield by closing in and hammering you with its Siege Turrets. It can also run you over for an instant kill, and will have an electric barrier that kills anyone that gets too close, which translates to electrified sides that will also kill you. However, while it is completely immune to all Guardian attacks, it is possible to cause a hull breach in it. To do so, shoot down the two plates that protect the hull (one on the left and one on the right) to reveal it, and then put out as much damage as possible on the vulnerable area. This must be done fast, or the Siege Engine will crush your team against a wall. If timed correctly, this will temporarily slow it down, which will buy your team some time to pick up three relics that will render the Siege Engine fully operational again, although these relics will greatly slow you down when carried and exhaust you after ten seconds. Failure to get these relics to the Siege Engine in time will result in them detonating, wiping the team. Have each teammate swap carrying relics and take them to the Siege Engine to fully operate it. Stay on there because it will break down the barrier that was previously blocking your path, which will cause an explosion that is an instant kill. After this has happened, jump off to continue.

There will be another wall in front of you. There will be three more of the same relics over there. But as you pick up the relics a Captain named Meksis, Siege Engineer will stop the Siege Engine. That is a signal that you must bring the relics to the engine. Switch relic carriers as needed. Those who aren't carrying relics by the time you reach the Siege Engine will have to take out Meksis. He is a durable opponent, but with concentrated fire, he should go down in a matter of seconds. Then your team may place the relics in their coordinating spots. This will, again, render the Siege Engine fully operational. It will break down the barrier once more, but after that, there will be a huge gap. Jump off the Siege Engine and descend into the gap, or you will die from the Siege Engine's detonation.

Heroic Mode Changes
The Siege Engine's Heroic Mode encounter has a somewhat different structure than Normal Mode. You will start off the fight as usual, although the Siege Engine will move faster than before and its turrets have an extended range, so shoot them down quickly. The encounter resumes as usual from this point on until the part where your team carries the relics over to the engine. When Meksis locks it down, a Perfected Walker will have been deployed. It has a lot of durability and firepower at hand, and can prove to make the encounter very difficult, but it has the same amount of health as any other Perfected Walker. Take it down quickly before you continue to put the relics into the engine.
