Tattoo Assassins
Tattoo Assassins was a Mortal Kombat "clone" that was never officially released due to the waning popularity of arcade games in the late 90s. The game was essentially finished before it was discontinued, although it had some minor gameplay and sound bugs. In 1994, prototype cabinets were released in test markets.
