The IDM (Integrated Defence Mechanism) is the defence system guarding the exit to the lift in Sunder Factory. The defence system has many different levels of protection for dealing with different types of threats. For example, some low-level defences are online at all times, such as window and door lock-downs which allow nobody to enter or leave. Although, more hostile levels of defence may be initiated if people try to reach the lift; if this happens they're burnt alive as soon as they reach the vicinity of the exit. The highest form of defence is only activated when the IDM notices repeated damage to the Factory or in the face of code-red threats. The IDM's most lethal form is when it implants it's consciousness into a mobile unit of destuction and utilizes all of it's weapons against the enemy.
