Captain a spacefaring steam locomotive as a new Victorian empire takes to the stars! Lead your hapless crew into trouble – and out of their minds. Smuggle souls. Barter for barrels of time. Stop for cricket (and a nice cup of tea). Sunless Skies: Sovereign Edition is the complete and definitive version of Sunless Skies. It incorporates the many additions made since launch – including new officers, enemies, engines, stories, and mascots, as well as a completely reworked region, a full steam mode for long journeys and desperate escapes, and the much-requested horn – as well as dozens of quality of life improvements.
