Angel RPG

The Angel RPG, based on the television series of the same name, is a game of modern horror, dark comedy, action, and drama. It features quippy heroes, ancient magic, urban demons, and the struggle against evil.

The game uses Cinematic Unisystem, the same system used in the Army of Darkness RPG and the Buffy the Vampire Slayer RPG. It's usually played in TV series-like campaigns of episodic sessions.
