Which feature introduced in Mortal Kombat 3 lets fighters sprint during a match?

Mortal Kombat 3 introduced the Run button, letting fighters sprint during a match.

The Run button was one of Mortal Kombat 3’s major gameplay additions. It allowed a character to move quickly toward an opponent while consuming a separate run meter. This encouraged more aggressive play and helped make matches faster than those in earlier Mortal Kombat games. The system was especially important for extending combos and maintaining pressure.

Mortal Kombat 3 also added the chain-combo system known as “Kombos,” as well as new fighters and the returning characters’ updated designs. The Run button should not be confused with ordinary forward movement, which is controlled through directional inputs. Later games changed or removed the system, but running returned in different forms across the franchise.
