Clarke was killed when he accidentally detonated his own pipe bomb, resulting in an explosion.
With all social order on Sevastopol broken down, Clarke joined with fellow survivors Elaine and Jameson. On the 7th of December, Clark wandered off alone to search for supplies, intending to use them to create homemade explosives for self-defense. However, while creating a pipe bomb, he inadvertently triggered the device in his own hands, the subsequent explosion tearing his body apart and demolishing the surrounding area, killing him. In an archive log, Elaine notes that all she found was a pool of blood.
Clarke was shown to be an expert in explosives. However, he was also shown to be careless, wandering off alone to search for supplies despite the obvious dangers. It was this carelessness that also resulted in his death, as his handling of a pipe bomb resulted in the device being detonated.
