Otto’s saferoom sits behind an 11‑lever switchboard inside the ACS Free Market on Free Market Station. You can reach it through a hole in the wall near the rift anomaly area and up a short ladder. The door uses three locks; each lock releases when a specific sequence of levers is flipped in order.

Prerequisite for visibility (N‑Ray Scanner)

You typically need the N‑Ray Scanner to see the hidden wiring that informs the puzzle’s logic. If you already have it, great—use it to visualize the live paths as you work. If not, you can still open the door by following the exact sequences below without visual cues.

The Outer Worlds 2 Otto puzzle solution (lever order)

Read lever positions by row, left to right. “Top/Middle/Bottom” refers to the three horizontal rows on the panel; “first/second/third/fourth” refers to position from the left on that row.

Lock Sequence (left → right on each row)
Lock 1 Top row third → Top row second → Middle row second → Bottom row first
Lock 2 Middle row fourth → Middle row third → Top row first
Lock 3 Bottom row fourth → Bottom row third → Bottom row second → Middle row first

Each correct sequence lifts one of the three door locks. If a sequence doesn’t register—no lock indicator changes—reset the panel state and re‑enter that lock’s order carefully from the beginning.
