Among the first optional missions available in Control Resonant, Crossing the Threshold becomes accessible after you arrive in Central carrying your Level 1 clearance keycard. The apparent mystery of the headless corpses hinges on a single discussion with Wilson. Choose the wrong responses and the mission still ends, but you receive no items.
Quick answer: Examine all the evidence, then at the warehouse side with Wilson and volunteer to host AVP-3. Take the entity to the Dig Site Threshold to receive both rewards. Choosing containment or accusing him ends the quest without any items.
How to start Crossing the Threshold
The mission triggers when you report a decapitated FBC agent to Zoe over the radio, not by talking to an NPC. The main story hands you the Level 1 clearance keycard at the Field Office, which is all the access you need to open the doors around the base perimeter and begin.
Either of two corpses can start the quest: one lies in the Field Hospital container, while the other is in the loading dock garage about a block west of the Field Office. For the garage body, look behind an open shutter in a side alley. Approach either one and interact to call Zoe; the mission then appears in your Quest Log.
The warehouse guards later in the quest hit hard. Coming back at a higher level makes that fight far more forgiving than pushing through the moment the quest appears.
Investigation route: docks, Dig Site, Field Hospital, and Security Station
Activating the quest places several markers around the base. You may visit the Dig Site and loading docks in either sequence; the route below limits backtracking and lets you gather all the necessary evidence before speaking with Wilson.
Reaching Wilson at the warehouse
The field-base walls prevent a direct walk to the warehouse marker. Use the map to reach the keycard-locked door, then leave the base through the correct gate. Hiss enemies ambush you as soon as you emerge.
North of the Field Office, the warehouse marker appears at roof height, though there is no way to use the roof. Approach from the northwest, eliminate the Hiss in the alley and building, and take the entrance’s right-hand door to find Wilson’s room.
Inside, expect flying Hiss on the upper level as well as Linus, a Hiss Pursuer – Apex mini-boss. Deal with the airborne foes first: filling their Falter meter makes them easy to stagger into an execution. Linus attacks at close range and can ignite you. Evade its spinning move, then strike during the lengthy recovery; rapid attacks can keep it stun-locked.
Wilson dialogue choices and outcomes
After defeating the Hiss, go through the door and talk with Wilson. He tells you AVP-3 is a young Threshold entity that requires a living host to stay alive. When a host dies, it moves to another person; this cycle is behind the FBC team’s headless bodies. For the ending that grants rewards, select the following responses in sequence:
- “What did you do to him?”
- “I saw something on the CCTV…”
- “Calm down, I believe you.”
- “I’ll take him.”
The dialogue wheel shows more options than these, but every path collapses into just two endings. The table below covers each result.
| Your choice | Outcome | Rewards |
|---|---|---|
| Believe Wilson, host AVP-3 yourself | Dylan carries the entity to the Threshold | Sensory Restraint Hood, Untapped Practice Knot |
| Believe him, but contain the entity | AVP-3 jumps to Wilson; he dies at the Dig Site | None |
| Accuse Wilson or demand quarantine | AVP-3 jumps to Wilson; he dies at the Dig Site | None |
If you opt to contain AVP-3, you get the empty ending, even if you previously said you believed Wilson. The entity then inhabits Wilson and he goes to the Dig Site; his corpse is later found in the pit’s center, and you receive nothing.
Deliver AVP-3 and confirm the quest is complete
Once you choose to host the entity, interact with Ranger Cox’s body on the ground; AVP-3 will enter Dylan. Your next objective is to take it back to the Dig Site Threshold. A new group of Hiss appears in the street as you leave the warehouse, and you may either engage them or run by.
For a fast return, follow the marker’s direction across the road from the warehouse rooftop. Climb the Dig Site scaffolding platforms, then drop into the illuminated yellow square. No activation or alignment is needed: landing in the rift releases AVP-3 on its own.
The completion banner confirms success and awards the Sensory Restraint Hood outfit plus the Untapped Practice Knot artifact recipe, which gives attacks against Heavy-tier enemies extra Falter. Zoe radios that Wilson surrendered over his team’s deaths, then a brief exchange about how much you disclose wraps up the quest. Verify in the Quest Log that Crossing the Threshold is no longer active.
