|Description||Enter Rasputin's bunker in the Cosmodrome and discover the source of the security breach.|
- S.A.B.E.R.-2 (Heavy Shank)
Summon the sparrow, drop on the shore to your left and just follow the waypoint through the narrow canyons.
Follow the path and Rasputin will drop a Warsat from the orbit. This will spawn a restricted zone, and you will have to defend the Warsat to acquire the codes that will let you access Rasputin's bunker. Fallen ship will immediately drop Wretches, Captains, Dregs, and Marauders, so clear them out and destroy ship's turrets. 3 more will come, armed with some Vandals, Servitors, and Veteran Assault Captains. By the time you clear them all out, you should have the code. Just drop to the level below and enter the Bunker.
As you come into the facility, you will be swarmed by Fallen. There's a security terminal at the end of the room that you should disrupt. Just open the vent cover and destroy it. This will trigger another enemy wave filled with Marauders and Exploding Shanks. Clear the room and go back, take the right and enter into the ventilation. Shoot at the ground below you to drop to the deeper level. You will soon come to a subway-like pathway filled with Arc Streams. Go to the left end of the room, pick up the charge and go back to deposit it. More Shanks and Marauders will attack, so drop the charge and clear them out. This will open the door right across the terminal where you picked up the charge. Head on inside and eliminate another Veteran Assault Captain and a couple of adds. This will drop the shield on the doors on your right.
A group of Fallen waits on the other side. After the battle is done, go up the stairs and drop to the arena below. After all enemies in the room are defeated, S.A.B.E.R.-2 Heavy Shank will spawn. Make sure to keep your distance and focus on clearing adds so you don't get overwhelmed. Also, pay attention to the Arc Streams, as they can deal quite the amount of damage. The boss alters the battlefield during the fight.
The boss' health bar consists of four segments. When it loses a quarter of its health, S.A.B.E.R.-2 shields itself and summons Fallen adds, which have to be defeated to remove the shield. When it is at full health, the boss fires from a Solar Wire Rifle which deals a huge amount of damage, and the two cores in front of it are its weak points. When the boss is at half health, it loses the Rifle and cores, attacking players with Void turrets. The weak spot moves to the glowing section on its front. When the boss' health is reduced to its last segment, S.A.B.E.R.-2 loses all ranged attacks and begins chasing after players trying to hit them with a powerful Arc melee. Its exposed core becomes the weak spot.
