"CHAMBER" is a playset for the PARAGON system in the AGON roleplaying game, set in 1968, where players work for a secret agency, CHAMBER, dealing with Signal Resonant Materials and their effects on people and technology, inspired by SCP Foundation, Control, and The X-Files. Agents must capture or destroy SRMs, contain the Signal's transmission, and handle related crises. Gameplay involves fast and flexible rules, and creating characters is quick and easy.
