What the sources establish
The supplied item search material includes Roblox video references, but not a verified official MONOCHROME item catalogue. Treat the keys and code as confirmed objective items; document any other item only after it appears in the live game or in a clearly identified MONOCHROME source.
Use the evidence carefully
Some source results are broad Roblox content rather than a developer-published MONOCHROME inventory. This page therefore does not pad the list with unrelated collectibles, badges, or items from other games.
Source note
This guide is based on the supplied MONOCHROME research corpus and the live Roblox game description. Video material is used as a real gameplay reference; it is not presented as an official patch note.
