"Mortal Kombat II" features an advertisement with the old "Revolution X" logo that arcade operators could toggle on and off. Occasionally after a large in-game explosion, Steven Tyler can be heard saying "Toasty!" in a high-pitched voice in reference to an easter egg in "Mortal Kombat II". The game was originally developed as a title based on the film "Jurassic Park". However, Sega acquired the rights instead and eventually released its own arcade game based on the film. Midway then retooled its concept to revolve around Aerosmith.
