To find Busken in Control Resonant, cross the rooftops in The Park to reach the rooftop FBC Base, then speak with the guard about Dr. Underhill. After you finish the conversation, the reported next objective is “Investigate Underhill’s Last Known Location,” south of the base on the same block.
How to find Busken at the FBC Base in Control Resonant
- Go to The Park. Follow the route across the rooftops toward the FBC Base.
- Reach the base rooftop. Busken is described as the guard stationed there. If you find the FBC Base fast-travel door, activate it; a walkthrough says it can help with later trips back to the area.
- Talk to Busken about Dr. Underhill. Finish the conversation to advance the investigation.
- Check your objective. Walkthroughs report that it changes to “Investigate Underhill’s Last Known Location.”
Where to go after speaking with Busken
Head south from the FBC Base, staying on the same block, toward the rooftop outpost where Underhill was last seen. Use the in-game map and quest marker to confirm the route if it differs in your game.
How to start the Underhill investigation
Walkthroughs describe “Ask Around About Underhill” as the first objective. One says New Growth becomes available during Zoe’s Briefing at the Watchtower, when Zoe mentions Underhill’s disappearance; another says you can begin the investigation by speaking with Busken if you skipped the briefing. These are guide-reported routes, not officially confirmed prerequisites.

Route details and version caveat
Third-party walkthroughs agree that Busken is at the rooftop FBC Base in The Park and that speaking with him advances the quest. They do not specify a tested game build or platform, and no official location documentation was available in the cited guides. If a marker or objective differs, follow the current in-game quest information.
Quick Recap
Rank #4
- RUST-PROOF ALUMINUM – BUILT TO LAST: Crafted from premium aluminum instead of ordinary tinplate, this metal wall decor develops a natural protective oxide layer that prevents rust, corrosion, and moisture damage. It stays pristine even in high-humidity areas like bathrooms, kitchens, and outdoor patios, far outlasting traditional tin signs that lose their shine and rust over time.
- HD UV PRINTING – VIVID & FADE-RESISTANT: Printed with industrial-grade UV curing technology for crisp details, vibrant color gradients, and exceptional ink adhesion. The ink chemically bonds to the aluminum surface, resisting scratches, sunlight, and daily wear. It stays bright and clear for years outdoors without peeling, cracking, or fading.
- PERFECT SIZE – LIGHTWEIGHT & STURDY: At 8 x 12 inches, roughly the size of a standard US letter sheet, this sign easily fills any blank wall while remaining eye-catching. The flexible aluminum bounces back from shipping bends or accidental dents—just straighten by hand with no creases left. Four pre-drilled mounting holes allow quick installation with nails, rope, or double-sided tape on any wall, fence, or door.
- PREMIUM METAL FINISH – VERSATILE DECOR: The smooth, polished aluminum surface delivers a high-end metallic look that elevates any space, far surpassing flat tin or iron signs. Ideal for man caves, garages, bathrooms, backyards, farmhouses, bars, and offices—also a durable, one-of-a-kind gift for vintage decor lovers.
