To renew player interest in Rainbow Six Siege's second season of its seventh year, Ubisoft dropped a revamped M.U.T.E. Protocol game mode. While the original M.U.T.E. Protocol was a heavily modified version of Secure Area, the new M.U.T.E. Protocol: Flesh and Metal takes cues from both Rainbow Six Siege's Team Deathmatch and other games' modes.
