i have a question to ask ab negotiator. how far are u allowed as a t? can u go all the way to the area around the elevators or even the elevators themselves?
As with any map, the defensive team is allowed to guard the objective. The variables that dictate how far a player can be away from the objective are too many to list, and it gets even more complicated if you're talking about a PCS Proven player.
Short version : guard the hostages, but be as creative as is tactically realistic.
