CONTROL Resonant Secret Hideouts — Washing Machine & ? Markers

PowerPyx-aligned Updated Oct 5, 2026

Secret Hideouts are self-contained puzzle rooms marked with a ? when you get close. Many use washing machine / laundromat on/off columns; the Unknown’s Pulse Fitness site is the gym puzzle. Solving each opens an underground stash — often a Health or Power upgrade chest. Clearing all unlocks Backroom Espionage. Short washing-machine focus: Washing machine guide.

Rules

  • Markers appear only when nearby — sweep zones after Map Kits.
  • Expect laundromat / machine / charge / Shift puzzles (example: washing-machine on/off columns).
  • Best after Shift + Reach so every hideout is reachable — Fault order: Where to go next.
  • Free-roam after credits is fine; nothing story-locks them permanently.

Why bother

Hideouts feed Personal Development / Astral upgrade trophies (Health “clown boxes” and Power “metal boxes”) and the platinum checklist — Trophies.
