Self-destruct



The Self-destruct is an integrated mechanism present in starships, UNSC bases and is used to cause a massive explosion to completely destroy itself in order to prevent vital navigational data and strategically-valuable information from falling into enemy Covenant clutches, as per paragraph five of the Cole Protocol.

Halo: Combat Evolved
In the level The Maw, Cortana and the Master Chief were forced to activate the Pillar of Autumn's self-destruct sequence in an effort to prevent the Flood parasite from getting off of Installation 04, and particularly 343 Guilty Spark from firing the Halo and wiping out all sentient life within three radii of the galaxy. Cortana and Master Chief's would have successfully worked had not aborted the self-destruct sequence, and Cortana was unable to reactivate the countdown, so the Chief proposed using explosives to cause the fusion reactors to go critical and explode, thereby destroying the ring.
