Onward to Venus is set in the retro sci-fi world created by Greg Broadmore. In this alternative reality space travel exists in an end-of-the-nineteenth century setting. There are planets and moons all waiting to be settled and exploited, although the local inhabitants might kick up a fuss. Fortunately for the Earthling civilisers there is a range of highly useful ray-guns, created by Doctor Grordbort, to convince the natives to behave themselves. Foremost exponent of the benefits of the good Doctor?s weaponry would be Lord Cockswain, recognised by all as the Earth?s best human.
Each player takes on the role of one of the major Earth-based empires, which are Great Britain, France, Germany, Russia and the United States of America. The aim of the game is to gain influence over the planets and moons of the Solar System by building factories and digging mines.
