There are multiple cut game modes, as revealed by the existence of sound files for them within the game's data. Some of these modes can even be played by hacking. These include:

• Arena: A game mode with no respawning. The objective was to kill all of the players on the other team, but if there was only one person left alive on each team, a flag would randomly spawn and the first person to capture the flag wins.
• Arms Race: Unknown. Only sound files remain.
• Defcon: There would be 5 Defcon phases which would count down. Play is normal at five. At four, each player goes into "Last Stand" upon death. Three makes weapons deal more damage. Two reduces the requirements for a kill streak by one kill. Defcon one disables respawning. After another minute, if one side has not eliminated the other, a nuke detonates, bringing the game to a draw.
• Die Hard: Team Deathmatch with Last Stand available for all players.
• Global Thermonuclear War: Involved protecting a nuke from the enemy team until the match was over.
• One Flag: One team protects the flag, while the other team captures it.
• VIP: Like Capture The Flag, except protecting a random player on the same team.
