I pulled this one out of Giant Size Freex 1. It really takes me back; I remember buying this game for my Sega GameGear (talk about a battery gobbler; that system used to run on six Double-A batteries and burn through them in a couple of hours).
Mortal Kombat was pretty hardcore for its time, although the “fatalities” that caused such a ruckus seem pretty tame by today’s standards. I actually sucked at the game, but had a friend who was pretty good. He played another friend’s 10-year-old kid and beat him so bad that the kid started weeping.
