Have you ever purchased a construction set and thought, "hey, this would be better if it had more interchangeable parts"? Well, I haven't, but that was the best symbol I could come up with.
Cayenne Quarry, a Vorpal Expansion, takes the simplistic Vorpal system and dumps in an extra box of pieces, allowing greater control of the game's mechanics and aiming the setting towards various popular genres (Gunslinger West, Zombie Apocalypse, and of course the Superhuman condition). These tried and true plotlines have been given the Vorpal treatment, so even if you don't intent to play them you can still expect wild and unpredictable hilarity to ensue.
Streamlined swarm enemy mechanics make keeping track of fights easier. Don't like the built-in invulnerability of Vorpal? Throw in the mortality mechanics. Trade who's in charge, justify those stray bullets on the floor, tie guns to pitchforks, and--as always--turn a boring friday night into a boring friday night with friends!
This is an expansion. It requires "Vorpal, an Indie Role-Playing Game" to use.
