Warband Science Fantasy Role Playing
Warband is a free RPG with a science fantasy, science fiction flavor. In truth, it could very well be the Warhammer 40K RPG. The author writes:
This game is my homage to the ‘grim, dark future’. A game of spikey power armor wearing, bolt-gun shooting, chain-sword waving chaos worshippers. Characters struggle to survive in the warp of space, as low-level members of a Chaos Lord’s warband, they strive to make a name for themselves and eventually captain a ship of their own.
