Breaking is a gamemode in which there are two teams.
The blue team has to protect an objective (checkpoint) while the green team has to break in.
One break in is acomplished when one player from the green team stands on the checkpoint protected by the blue team 5 seconds, without getting killed.
The green team wins when they manage to break in 5 times before the time runs out.
The blue team wins if when the time runs out, the green team hasn't managed to break in 5 times.
One of the mini-games in this gamemode is "Breaking the Bank" in which the robbers have to rob a bank while the cops are protecting it.
