Judge Dredd Megazine 400 is an issue of Rebellion's long-running anthology built around the lawman of Mega-City One. The lead Dredd strip The Trouble With Harry runs alongside Anderson: Psi-Division, Blunt, The Dark Judges, Devlin Waugh, Lawless, and Storm Warning. By this point the title had settled into a monthly schedule, still bundled with a reprint supplement.
