The prepped Greg brain is a quest item in the Fallout 76 update Wastelanders.


It is the brain of Greg Goldstein, preserved in a jar and chemically prepared for installation into a robobrain.


It can be obtained by successfully preparing Greg's brain at the RobCo Research Center during the quest Duty Calls. Doing so will remove Doctor Dias's brain and Gina's brain if they are present in the player character's inventory.
