Tharg's 3rillers is a short story format in the vein of Tharg's Future Shocks. Unlike the Future Shocks, 3rillers consist of a self-contained story which runs over three Progs. Matt Smith commissioned the first run of three stories when there was a nine-week slot available in 2000AD. The first of the Tharg's 3rillers appeared in 2000AD Prog 1740.
