Viper Beam is one of Cable's special moves where Cable takes out a big gun and shoots a blue beam at the opponent. The beam can be changed by pressing the Punch buttons and can be controlled by pressing up and down. The light punch version does 15 damage with 4 hits and the heavy punch version does 18 damage with 8 hits. This move can also be done in the air with the same damage and hit mechanics as the ground types.
