Arcade is a playlist in Tom Clancy's Rainbow Six Siege introduced in the Operation Void Edge expansion. The playlist offers limited-time game modes that modify elements of existing modes and is usually on a smaller scale compared to regular event game modes. The Arcade playlist also includes returning events like Rainbow is Magic.
Each new expansion will see the release of a new limited-time gamemode. Ubisoft plans to eventually release more than one limited-time gamemode for each expansion.
