WangBang

WangBang is a competitive multiplayer game mode in Shadow Warrior, similiar to BloodBath in Blood. Whoever gets the most kills until the frag limit or a timer runs out wins the match.
Additionally, players had a "Play with Nuke" option upon starting a match, disabling which would result in all nuclear warheads replaced with missiles - that might be the first ever instance of a multiplayer game allowing to disable casual gameplay elements for the sake of sportsmanship.
