The Campaign - Taras Nabad

Head through the linear tunnel and into the sunlight. To the left, jump to a platform, kill approaching Zombies, and grab a Codex entry.

Drop down a ledge, melee the wall on the right, enter, and grab a Sentinel Battery.

Return to the main path and cross the bridge.

Defeat the Cyber-Mancubus, Hell Knight, and fodder. Melee the switches on the two statues to open a door.

A Marauder will appear with infinite fodder. Maintain medium distance, dodge when it glows green, and attack. Use your preferred weapons.

After the Marauder is defeated, proceed to the end of the area. Swing on the bar to the left to reach a Secret Area containing an Album. Alternatively, walk off the ledge backward and dash into the opening.

Cross the area, turn left, climb the wall, and jump onto the bridge. Defeat the Zombies and Mancubus at the end.

Head left to grab a Suit Perk Point, then right to drop down a gap. Grab the health and exit back outside.

In the open area, many Demons will spawn, including the Archville. Prioritize killing the Archville on the upper right to disable its Totem effects on other enemies. Defeat the Prowlers, Revenants, Dread Knights, Pain Elementals, Cacodemons, and fodder. Use the charged Ballista mod or homing rockets to manage the crowd.

Instead of heading to the objective marker, pull up your map. From the objective marker, head right and follow the path to an Auto Map-Station.

Melee the switch to move a statue and drop down.

Head right and enter the area under the balcony. Smash the cracked wall to find a Secret Encounter.

OPTIONAL: Secret Encounter: Face a Cacodemon, Pain Elemental, and Doom Hunter. Use grenades and charged Ballista shots. Glory Kill the Cacodemon and Zombie, then focus on the Doom Hunter, breaking its shields and using rockets.

To the left of the Secret Encounter area, press the button. Follow the statue out, turn right, and grab a Mastery Token.

Return to the statue with stairs on either side. Climb the right stairs, turn left at the small steps, and smash the statue.

Press the switch behind the statue. Follow the balcony, kill the Zombie at the end, climb the wall, turn around, smash the chain link, and drop down to grab a Sentinel Battery.

Go back to the statue, press the button on its back, and jump into the water.

Grab the Radiation protection. Swim down and melee the cracked wall facing the entrance. Head through, grab the other Rad protection. A section of the water will drain. Shoot the small green button, grab the Rad protection, jump down, swim through, resurface, and climb up at the end.

After exiting the water, kill the Prowler, Pinky, and Gargoyls. Grab the visible Suit Perk Point.

Head outside, grab the visible Codex. Look to the right for a cracked statue.

Smash the statue, press the button, and climb the stairs. Stand on the platform with the glowing rings to open the gate with a Secret on the opposite end. Grab the Cyber-Mancubus Toy.

Go back up the stairs, open the door, and watch the scene. Circle around the ring and grab a Codex entry.

Drop down under the main ring to find a 1-Up, accessible via double jump/dash.

Head into the next area, which contains tough enemies: a Doom Hunter, Dread Knight, Prowler, Pain Elemental, and fodder. Drop down, use the Chainsaw on fodder near the blue column on the right, turn, and dash right to the upper ledge to grab BFG ammo.

Use the BFG 9000 to destroy the Doom Hunter's shields and sled, and damage surrounding enemies. Finish off the Doom Hunter and any survivors with rockets.

After clearing the area, use the ledge on the upper level, to the left of the entrance, to melee an object.

Drop down, run to the other side, enter the alcove, and melee a switch. This will open an elevator in the floor.

Head down the elevator. In the tunnel, the first flight of stairs to the left leads to a Slayer Gate.

Take the stairs on the right, grab the Rad Suit, and jump into the water. Turn around and swim through the opening.
