Expert Nova Ð a role-playing game for action and mysteries in settings from the late Victorian era to a near future. Put your players to the test in LondonÕs seedy alleys, the trackless jungles of the Amazonas, the catacombs under Paris, or the TemplarsÕ hidden headquarter. The game's flexible rules favour playability and encourage clever schemes and social interaction. Its speedy character generation produces hardy and versatile adventurers. Action is skill-based: roll 1D20 as low as possible. You adjust the grittiness and lethality of your adventures by applying optional rules. The campaign design guidelines has a 1950s Australian science fiction setting as a hands-on example.
