Blackbone:252

Inspired by the Dai Dark manga series by Q Hayashida. 

You have been pulled back from the Void of death to unwillingly participate in a galactic battle royale for the right to fight a god. You, and everyone else who has ever died. 

Blackbone:252 is a lightweight system that enables fast, space-faring carnage in a brutal, biomechanical world where the only currency that matters is death.
