A dieselpunk roleplaying game of action, mystery and mad science!Tomorrow City was one of the cities of the future, built to usher in a new age of prosperity, seizing upon scientific achievements at the dawn of the twentieth century. Then came the War. Radium-powered soldiers assembled, diesel-fuelled nightmares rolled off production lines, city fought city, and the world burned in atomic fire. We survived, barely. Tomorrow City still stands, an oil-stained beacon of hope, part-refuge, part-asylum. Beset by dangers from both within and without, a secret war now rages on its streets. Diesel-born monstrosities stalk the alleyways, air pirates strike from the wastelands, mad scientists continue their dark work, occultists manipulate the city's strange geometry, and secret societies plot in the shadows.Tomorrow City is a roleplaying game of dark science and dieselpunk action. Swift and simple character creation and an easy-to-learn dice pool system places the emphasis on unique personalities and the momentum of the plot. Join the Underground and fight the crime and corruption at the heart of the city. Sell your dieselpunk tech, occult knowledge, and sheer grit as troubleshooters for mysterious paymasters. Hunt down spies, saboteurs, and science-run-amok. As weary sky rangers, fringe scientists, and radium-powered veterans, you might be all that stands between a better tomorrow and no tomorrow at all.
