Many years ago I started writing an RPG game system and setting I called Black Dawn. It was a mash of Shadowrun and Battlelords, combining future-tech, dystopia, and space travel. The system plays pretty smooth if you can add numbers quickly in your head but the character creation process is clunky. I’m making a PDF available for any and all to download and toy with. There’s a heap of gear, cyberdecks, vehicles, powered-armour, spaceships, custom power armour, custom vehicles, and custom spaceships.
I will be revising the whole thing over the coming months.
