Self-destruct is a mechanism used to cause a device and/or structure to destroy itself.

The exact damage is generally related to the size of the device or structure it is installed into. Self-destruct systems are often used by technology using races such as the Terrans and Protoss.

While most races try to preserve units and building for as long as possible, the Vaul install such devices in all their technology to prevent capture and leaving witnesses (Mass Effect: Mechs). To avoid harming their own forces, their Plasma shields are set to a frequency to minimize or neutralize the brunt of most explosions.


  • All Vaul units and structures self-destruct upon defeat with 20 and 100 explosive splash damage respectively
