CONTROL Resonant Ahti — Where Is the Janitor?

Lore / appearance Updated Oct 5, 2026

CONTROL Resonant Ahti (the Oldest House janitor) is in the game — but he does not wander Manhattan or the Oldest House like in the first CONTROL. Fans searching “ahti control” want his Resonant appearances.

Where to find Ahti

  1. Progress the story through Sever the Hedron Links.
  2. Play Rebuild — the retro / memory flashback.
  3. In the Oldest House memory interludes, Ahti appears humming near a yellow mobile lab (Finnish tango vibes intact).

Epilogue postcard

After the campaign, in Dylan’s apartment (Epilogue), pick up the Season’s Greetings postcard from a shelf. It’s from Ahti and points to Cauldron Lake, Washington — a nod to where the janitor may be “on vacation.”

Not a side quest There is no open-world “find Ahti” board job. If you’re stuck looking for him in FBC Manhattan hubs, you’re looking in the wrong place — finish Rebuild / check the apartment postcard.
