The Chum's Hideout is a location in Mad Max video game.
"Located in a gigantic tanker in the Great White, Chumbucket the mechanic found this place he believed was the perfect location for his "Sanctum" and began building his wondrous Magnum Opus here. Down in the steel temple, he found water trickling from one rusted wall and on another there was food growing on the rust and steel. There were algae and mollusk alike in this dry hell, underground and encapsulated in steel.
Here he built his tabernacle and waited for the Saint to come." - Mad Max video game description
