GameBattles is online Competitive gaming, similar to MLG (Major League Gaming) which certain rules are set to make the game "less nooby" such as no ghost, awareness, no spy planes, guardians, counter spy planes etc. There are specific weapons not allowed and certain attatchments such as no launchers, no grenade launchers, no target finder etc. i hope this helped a few :}
