Defcon, also known as Örli Wörks (Early Works), is the first release by the German industrial music project Wumpscut.

Defcon appeared in two different editions, with two completely different track lists.

Most of the songs that originally appeared on this release were released later on the Wumpscut compilations, The Mesner Tracks, Preferential Legacy, Blutkind, and Preferential Tribe.

Both editions of this tape are extremely limited to 50 copies.
