After some delay, Salvage Trader is now out for Windows 8, and available in the Windows Store.
Additionally, the Windows version is the first to feature the first update to the game itself. It includes new keyboard shortcuts, greater ability to pause and load the game, greater variation in the NPC encounters, both in graphics and flavor text, and a number of bug fixes and minor tweaks. Much of what has been added and changed was based on feedback from players, which is very much appreciated.
The Windows version requires Windows 8+, a keyboard and a mouse, as well as a Microsoft account.
