Special Moves are moves that are unique to only one character. Each character has a list of their own special moves, and each move requires a simple button sequence to activate, similar to execution, but not killing the opponent and open for use at any time. Some well known special moves are Cyborg's plasma moves and V1-Hyper's hair whip move.
In Rise 2: Resurrection, each robot possesses at least one projectile attack move. Doing so will enhance the damage of the special move slightly, or increase its effectiveness. For example, like if you finish them with your Execution Moves, you get to have one random projectile. These moves are often used to set up and finish combos, as well as increase the amount of damage performed in the combo, without increasing the number of moves.
