X01 bosses: Captain, Wheelson, Knuckle and Wrench

Choose the boss for the objective you need, identify a retreat and clear nearby threats before committing. Captain, Wheelson, Knuckle and The Wrench have different roles; a kill, a key pickup and successful extraction are separate results.

Prepare the fight and the exit

Bring enough armor, healing and ammunition to disengage if the encounter goes badly. Keep one retreat clear and avoid having the whole squad reload or cross an exposed approach together. These are planning recommendations, not a guaranteed solo strategy or damage formula. Use the X01 map to orient after arrival.

The Captain: guards, cover and a deliberate pickup

The Captain is a Juggernaut Commander with elite guards. Work from cover, deal with nearby guards when possible and avoid committing every teammate to the same exposed doorway. Reposition to recover rather than forcing another magazine while unprotected. A fixed spawn is not established here.

After the fight, inspect the loot for Deep Vault 301 and Specter Fabric Sample. These are observed possibilities, not guaranteed rewards. Collect the named card before following the Vault route. If a Captain Threat Briefing is active, check separately for its requested helmet section and extract for event credit.

Wheelson: interrupt, reposition, collect the module

Wheelson patrols Logistics Tunnel. Use the red patrol line to understand its reported path, not as a live position tracker. Avoid fighting from the middle of its lane; choose solid cover and a retreat first.

DDoS and Shock Stick effects can disable its turrets; the 7 November patch fixes turret rotation continuing during those effects. Use an interruption to move, reload or recover, then reassess before exposing yourself again. No fixed disable duration or ammunition requirement is established here.

After destroying it, collect the Remote Module for the Power Generators control sequence. The module is one step of that route, not an automatic extraction.

Knuckle and The Wrench: find the encounter, avoid a blind push

Knuckle / Tae-Hyun is reported in Data Center. The Wrench / Chol-Min is reported in Motorpool, with tanks involved in the encounter. Use those areas as search leads, check sightlines and keep a clear route back before advancing.

Guaranteed spawns, signature drops, complete reward tables and a repeatable special tactic for either Lieutenant remain unverified. Inspect actual loot instead of assuming a specific Vault card. For a shorter trip, choose one objective-chain route and leave optional boss fights for another deployment.
