Banned Weapons
Weapons banned from MLG "Call of Duty 4: Modern Warfare" tournaments include most explosives. Grenade launchers, C4, claymore mines and the frag x3 perk are also all banned from tournament gameplay. Players caught using these weapons are in violation of the rules, and both the player and his team will be subjected to punishment.
Banned Exploits and Tactics
Like most games, "Call of Duty 4" has a few issues in its programming that players may at times use to their advantage. MLG tournament rules ban the use of such exploits in general, as well as on specific maps. The rules prohibit going outside of the normal boundaries of the map, going into the tunnel wall on Pipeline, going to the top of the arch on District, going onto invisible ledges, and jumping off of other characters. Additionally, players are not allowed to remove players on the other team from the match once a game has begun.
Punishment
Breaking any of these rules, be it a weapons or movement violation, results in the same punishment: forfeiture of the game. Any player caught using one of these banned tactics will automatically force their team to take the loss.
