Find Lost Items From the Old Capital in Hollow Zero

The Hollow Proposal Commission will become available after finding the four items associated with it. These items only start appearing after you get both Lucky Ticket and Measurement Device. You are also limited to only three items per day, so keep checking Hollow Zero for items.

Lost Item Recommended Locations
Old Capital Metro Construction Ruins
Preview of Secret Path Tile
Hollow Zero Frontline Lost Item Tile 1
Hollow Zero Frontline Lost Item Tile 2
Old Capital Metro Interior Pattern 1

Lost items are collected from Secret Path tiles in Hollow Zero, and you can get up to 3 items per day. You do not need to complete Hollow Zero stages to obtain Lost Items as quitting lets you keep them.

Simply load up a stage, check if a Secret Path tile is present, then exit and reload the stage again until the Secret Path tile is present.

We recommend doing this at harder levels, such as Core or Heartland, for a better chance of finding the Lost Items. The most recommended stages would be the Old Capital Metro and Construction Ruins.
