The name of the mission "Body Harvest" is likely a reference to the Nintendo 64 game of the same name, produced by Rockstar North when they were DMA Design. It is arguably Rockstar's first free roaming 3D adventure, setting the precedent for GTA III to follow. The use of the Combine Harvester is likely also a reference to Body Harvest, as a part in the game involves the use of a combine harvester to run over zombies.

At one point during development, the Combine Harvester had a green body color, no step bars into the driver cab, and a less detailed combine head.
