A video overview of this game mode is available at https://www.youtube.com/watch?v=UN6Q_CkEVnI

Siege mode has been released as of August 14th 2012. Players are divided into two teams, one team is classified as the escorting team and the other defending. The attacking team must escort the Scorpion Tank, a four legged mechanical tank to the destination. Facing resistance from the defending team along the way, including road barricades that need to be lowered by hacking a near by panel. There are three different panels and barriers that the escort team must overcome. Hacking each barrier grants your team a rather large point increase. Hacking a panel also resets the timer to 2:59, giving the escort team more time to advance the tank. The Scorpion Tank can be disabled but will become enabled again after a short amount of time. It also has a weak spot on the back end of its turret.
