In September of 1999, along with the debut of the highly anticipated Sega Dreamcast, Midway released an upgrade of Mortal Kombat 4 as a launch title for the console. Mortal Kombat Gold was essentially Mortal Kombat 4 but with improved graphics, more arenas, and the addition of Cyrax, Kitana, Mileena, Kung Lao, and Baraka. Sektor also made an appearance as a secret character, as well.

The first release of this game, however, contained so many visual and gameplay glitches that Midway was forced to release another version with most, but not all, of the glitches corrected. People were able to bring their defective copy back to the store where they had purchased it to exchange it for the new version, free of charge. Was this problem due to Eurocom's inexperience with new console hardware, or just laziness on Midway's part for fishing the game out to a 3rd party developer for the conversion? I guess we'll never know.

Thousands of years ago in a battle with the fallen elder god known as Shinnok, I was responsible for the death of an entire civilization.

To rid all realms of Shinnok's menace I waged a war that plunged the earth into centuries of darkness and banished Shinnok to a place called the Netherealm. Now after Shao Kahn's defeat at the hands of the earth warriors, Shinnok has managed to escape his confines of the Netherealm.

The war is now being fought once again, and this time it can be won by mortals.
