Plenty of members of Arknights Endfield’s roster offer up side quests as you progress through the main story, with a few sectioned off as full Narrative Events.
Wulfgard is the subject of one such Narrative Event, with a member of his Pack requesting the Endministrator’s help in rooting out a traitor. With Oroberyl and plenty of leveling materials on the line, why not help out a friend?

Starting the Quest

To start Lone Wolf, players need to look out for a message from Rossi in the Baker menu. This will initiate the quest proper; speak with Rossi in the Mining Camp at Origin Lodespring. She’ll send you off to track Wulfgard down in the Power Plateau.
You’ll find Wulfgard deeper into the Bridge Approach Camp to the far left of the map. Entering the camp will prompt you to enter Immersion Mode, locking you into fighting with Endmin and Wulfgard.
Finding the Traitor

Endmin and Wulfgard head deeper into the camp before Wulfgard stops, requesting you stay on the traitor’s trail. You’ll run into a group of Landbreakers, and after a short fight, one will reveal himself as one of Wulfgard’s spies.
This spy, Giovanni, gives some info that clashes with what Wulfgard knows, so you both agree to let him follow to keep an eye on him. Wulfgard theorizes that Giovanni may be one of many traitors and suggests springing whatever trap he has in store.
You’ll then be warped to the Valley Pass, where Wulfgard will recommend speaking with some of the UWST Crew stationed nearby. Wulfgard puts together that the Bonekrushers must be kidnapping UWST staff and rebuilding a local base.

You’ll next need to scan the environment, following the trail of a missing UWST scientist. You’ll find him up a few ramps, knocked out behind a destructible wall beside a chest. His testimony confirms Wulfgard’s suspicions; all that’s left is to meet back up with Giovanni.
He’ll lead you straight to the entrance of the Bonekrusher’s underground camp, blocked off by fire traps and a quick combat encounter. At the very back of the area, you’ll find a large sewer pipe, the entrance to the camp itself.
Storming the Bonekrusher Camp

The Bonekrusher’s camp is a veritable dungeon, a massive repurposed underground UWST facility.
After a quick ambush, you’ll run into a locked gate and a wall of switches with Bonekrusher glyphs above them. Approaching the suspended triangle will allow you to see Bonekrusher markings left in the environment, guiding you to an overlook nearby.

From there, the code is revealed: the Face, the Sun, the Running Man, the Feet, and Fire. A nearby wall will open, leading deeper into the camp. After a few fights and a couple of gondola rides, Giovanni runs ahead, tricking Endmin and Wulfgard into a trap.
The two fall, and after a heartfelt apology from Wulfgard, are tasked with dodging a series of flame traps. Lean left as you head forward, following the objective marker as you continue ascending.
Eventually you’ll make it back into the base proper, as Wolfgard disables the traps. Behind a few bandits is an elevator, which Wulfgard notes as the point of no return. You’re met with the leader of the occupying bandits, a two-stage fight that doesn’t pose much trouble.

As he falls to his knees, Giovanni appears, killing the bandit before getting into a heated argument with Wulfgard. Giovanni reveals himself as a member of the New Pack, a splinter group stemming from Wulfgard’s Pack.
Giovanni leaps at Endmin before being cut down by Wulfgard. The two leave the camp with more questions than answers, but the traitor lies dead, mission accomplished.
You’re teleported to The Hub, where Wulfgard is giving Giovanni his funeral rites, mourning both the traitor, and his old friend Tommaso. The Endministrator joins him, and the two leave Giovanni’s knife stabbed into the ground as a solemn reminder.

Wulfgard requests that Endmin keep the entire excursion between them, as he works to find more on this New Pack. With that, the Lone Wolf is cleared, with a sizable chunk of oroberyl and leveling materials to show for it.
