Cube 2: Sauerbraten

Commercial

Cube 2: Sauerbraten can be seen in a Burger King television commercial from 2006. The commercial shows a guy doing "typical guy stuff" when his girlfriend is out of town. He's neglecting household chores, partying all day long, eating burgers, playing video games and having threesomes.

During the video game part, the guy holds a GameCube controller and gameplay footage of Cube 2: Sauerbraten can be seen briefly. The game was never released on the GameCube, the video editors probably just needed a free game they could show without having to pay royalties.
