On the website for the game OmniBus, a special edition of the game was offered for $7,500 that came with the game, soundtrack, and an actual MCI bus. The publisher Devolver Digital claimed that the bus "may or may not have been used to motion capture lifelike bus movement for the game." The website also links to a "free" edition of the game, which simply allows people to download and print off papercraft templates to make their own bus model out of paper.
