I remember when we first put in the uppercut move. Basically, you duck down and hit the high punch, and the guy delivers this uppercut move that launches your [opponent] way up in the air and he lands on the ground and the screen shakes—just the most explosive, powerful-feeling move. I remember people sitting in my office all day just doing this uppercut again and again, like 'Oh my God, that feels so good.' It just became the cornerstone of [the game]. That was a big moment. It sounds odd, but people would be coming into my office and saying, "Let me see that uppercut move everybody is talking about."
Another one is Scorpion's spear. That, to me, was clearly the one move that I remember really set Mortal Kombat on a different path than Street Fighter. Street Fighter is an amazing game; they had projectiles. That was really kind of special. These characters can shoot energy out of themselves.
When Mortal Kombat got the spear out and it would attach to the other guy, they would shake and you would pull him in and hear “Get over here.” Then, you got that salivating free hit; usually, people would do an uppercut. That was really the defining moment of "Okay, this game is going to go in this direction. This is what this game is going to be all about"—just over-the-top moments. Scorpion's spear, Sub-Zero freezing a guy, Raiden diving and teleporting behind you—all of those things became very defining moments—but the Scorpion spear is the biggest one.
