Siege Mentality

Siege Mentality is a group of missions in Grand Theft Auto Online. They were included in the Heists Update as part of the Adversary Modes.

Overview
The players are put into one of two teams. A team of Hold Outs and a team of Attackers. The Hold Outs team's objective is to survive four real-time minutes whilst staying in one location. The Attackers' objective is to kill all of the Hold Outs.

The Attackers have unlimited lives, whilst the Hold Outs have one life each. If the Attackers managed to kill all the Hold Outs, then the Attackers win the round. If the Attackers fail to kill all the Hold Outs in four minutes, then the Hold Outs win the round.

During these missions, the Attackers are armed solely with Sawed-Off Shotguns, whilst the Hold Outs have many powerful weapons at their disposal. If a Hold Out leaves the location of the mission, they will be disqualified from the round.
