The Mapping BioChip (aka BioChip - Mapping) is a biochip in The Journeyman Project Turbo! and earlier versions (it also appears in Pegasus Prime as the "Mapping Biochip, but functions differently).
When activated, the Mapping BioChip automatically records where agent has walked. Upon reactivating the BioChip in an area which has already been mapped, the map of that location will be retrieved for the agent in its previous state. It was found in the Temporal Security Annex in 2318.
