Its a specific game mode like TDM, but the dead enemy (or friend) will drop dogtags when killed. You or the enemy can retrieve the dogtags. Retrieve your friends dropped tags to keep the "kill count"/tickets down.
No matter what game you are playing, there will be campers. Look at what they tried to do with barebones, that didn't stop anyone. The only thing it did was take away all the easy outs for getting rid of campers. Man that game mode was a mess. The only
way I could see this eliminating camping is if they make the kill confirms count towards killstreaks and not the kills themselves.
