From publisher blurb:
The Offspring is a story roleplaying game about angelic beings caught in an endless war with the Nephilim. Players take on the roles of angels and other heavenly beings turning their gaze from the plight of man in a final attempt to thwart the enemies of humanity. In the quiet moments before the final battle, angels question the validity of the war and the purpose of god’s first offspring — the Nephilim.
This game is designed to be played in conjunction with Born from Hate.
Each game in the Protocol series is zero-prep for 3 or more players.
The game length is exponentially long, so games with more players take more time to complete. The Protocol Series requires a deck of poker cards as well as tokens to track drama points.
