GECK

The Garden of Eden Creation Kit or GECK was the item The Chosen One was sent to find by the Village Elder at the start of Fallout 2. It was first mentioned in the Fallout manual.

The kit looks like a smallish, silver briefcase emblazoned with the letters G.E.C.K., and contains all the seeds, fertilizer and gizmos, even a cold fusion power generator, required to revitalize areas of the wasteland. Each Vault was presumably issued with two GECKs, except for Vaults 8 and 13; Vault 8's extra GECK got swapped (whether by accident or some nefarious scheme, this is not known) with the Vault 13 surplus water chips that were ordered when the one working water chip broke.
