Prerelease Info

Shinnok

Shinnok, a character normally playable in all other versions of the game except this one, can be selected with the GameShark code 0109F0C0. Interestingly, his special moves can be executed by the player!

• Spear: Down, Forward, Punch
• Dash: Down, Forward, Kick
• Fatality: Down, Down, Away

He does not have his own ending text, and his physics are still geared towards being a boss character.

Unused Graphics

A simple rocket. Sektor used this as a special move in Mortal Kombat 3.
