In one or two player several special moves can be performed by both characters standing close and a player pressing certain buttons simultaneously, the move differs depending on which buttons are pressed and whether the player is controlling Ren or Stimpy.

In one player the player controls either Ren or Stimpy and the computer controls the other character who will simply follow however, the player can swap the character they control at almost any time during game play.
