The first time I played Mortal Kombat [official site], Nintendo had replaced all the blood with sweat, which seems like the kind of extreme detox plan Gwyneth Paltrow might be promoting next week. Instead of actually playing the game, I spent all of my time trying to figure out how to enter the cheat code that would activate the gore and fatalities, little realising that such a code only existed on the Genesis version of the game. The SNES was Sweat City forever.
These days, the cool kids edit files instead of entering cheat codes. A redditor by the name of XVermillion has unlocked previously unplayable characters Rain, Sindel and Baraka by renaming references to assets in the source files. Instructions are here.
The implementation isn’t perfect. Movesets are incomplete and while you won’t find yourself stuck in Sweatsville, don’t expect a full set of X-Ray moves and Fatalities. It’s not outside the netherrealms of possibility that these characters will be fleshed out in DLC packs further down the line so perhaps you could consider these half-formed versions to be a teaser.
I played the first few fights of the Story mode over the weekend. There are long cutscenes depicting a war between military special forces and flying demons. There are QTEs. Johnny Cage punches Sub-Zero right in the snowballs.
