Rock is one of the Emotes in the game Brawlhalla . When used, the player will make a rock-paper-scissors motion with their fist until the emote key is released, at which point they will throw their hand in the shape of rock. If a player owns the Rock , Paper , and Scissors emotes, the Random RPS variant of the emote will be unlocked which will randomly select one of the three emotes when used.
