About The Difference Engine
Each lever adds its value: 128, 64, 32 and so on down to 1. Set them so the dials read exactly the navigator's number, first plain numbers, then sums and Roman numerals, against the clock.
Based on Imperium Astra by A.C. Valerius, a sci-fi series in which history skipped the Dark Ages and a Roman Hegemony and the Han Dynasty carry their eternal war to the stars.
Imperium Astra
The Difference Engine is a free companion game to Imperium Astra by A.C. Valerius. If the game hooks you, the full story continues in the book series.
