Kill Team: Shadowvaults is the campaign and rules supplement from the Shadowvaults expansion for Warhammer 40,000: Kill Team. It provides background lore and a 120‑page rulebook detailing the mysterious Gallowdark space hulk setting, and introduces two full Kill Teams — elite Astra Militarum Kasrkin and the Necron Hierotek Circle — complete with datacards, equipment, specialist options, and faction rules. It also includes Shadow Ops and Critical Ops missions and additional killzone rules for things like sentry turrets and robots, all designed to expand narrative skirmish play within cramped space‑hulk environments.
