VintageBeef's Mars Base would be VintageBeef's main base throughout Season 4. VintageBeef took inspiration from the red sand of the mesa, seeing its similarity to the red surfaces on Mars. As a result, he started constructing his Mars Base. The base featured a large biodome and a large central hanger as well as many rovers and other supply crates around the area. In VintageBeef's final episode of Season 4, he commissioned MumboJumbo to build a piston door for the entrance to the Mars Base.
Due to VintageBeef joining the server mid-way through Season 4, the base was never fully finished, but remains one of the cooler additions to the Southern Residential District.
