If you mastered all of Mortal Kombat II you've probably noticed that, unlike other characters, players never get to take control of the true CPU character Jade. Now this hack from abystus does just that, allowing players to take control the “secret” character that has never been accessible before. The reward? Just watch the Jade playthrough above.
If you're up for hacking your own emulator there are details here. Otherwise just enjoy the classic bloodfest of Mortal Kombat II and the reason why your mom wouldn’t let you go to the arcade.
