About Lost Item

Lost Item is a short, single‑player adventure that begins with you waking in a late‑night office. A single sheet of paper on a bulletin board instructs you to patrol to the 10th floor and collect every Lost Item you encounter.

A perfect patrol requires picking up all items and placing them in the collection box; any missed item sends you back to the 1st floor. Runs last roughly 15–60 minutes and feature paranormal phenomena, multiple endings, and 16 Steam Achievements.

01 / THE GUIDE

Core Objective

The only directive you receive is pinned to the bulletin board: patrol to the 10th floor flawlessly and place every Lost Item in the collection box. No other goals are presented, making the patrol itself the central task.

If a single Lost Item is missed, the game resets your position to the 1st floor, forcing you to restart the patrol. This loop continues until a flawless run is achieved.

  • Observe early‑floor item locations to anticipate later placements.
  • Treat each floor as a separate segment and master it before moving upward.

02 / THE GUIDE

Lost Items

There are 100 distinct Lost Items scattered throughout the building. Each must be collected and deposited in the collection box to satisfy the perfect‑patrol requirement.

Collecting some items can trigger various paranormal phenomena, adding an unpredictable layer to the otherwise straightforward collection task.

  • Note which items cause phenomena; they may hint at hidden patterns.
  • Keep the collection box in view to avoid overlooking a deposit.

Patrol Mechanics

The patrol proceeds floor by floor, ending at the 10th floor. No timed input is required, allowing you to move at your own pace without a countdown pressure.

The game presents a linear ascent through each floor; no alternative routes or shortcuts are documented, so the implied path is a straightforward climb.

  • Adjust camera comfort settings to improve visibility of items.
  • Maintain a steady, unhurried pace; rushing offers no advantage.

Endings & Achievements

A flawless patrol can lead to multiple endings, though the exact triggers beyond perfect collection are not detailed in the source material.

The game includes 16 Steam Achievements that track milestones such as item collection, floor progression, and other undisclosed criteria.

  • Aim for a perfect run to unlock the greatest variety of endings.
  • Review the achievement list after each session to identify remaining goals.
