Endless Space Collection is free on the Humble game store. However, there is only so much time before the deal runs out. As of this writing, you only have 39 hours to claim the collection before it shoots off into the black.

Endless Space Collection is a, erm, collection of two Endless Space games. The first one is, naturally, Endless Space, a galaxy-spanning strategy game that launched back in 2012. Its DLC, Endless Space – Disharmony, is the second in this two-part act. The original game scored well with critics. Currently, it holds a 77 at Metacritic, with reviewers praising the game’s atmosphere (ha, I get it!), fluid gameplay, and accessibility.

“This galaxy is ancient, and its first intelligent life was the civilization we call the Endless,” reads the game description at Humble. “Long before our eyes gazed upon the stars they flew between them, though all that remains of this people is what we call Dust. A substance found scattered or in forgotten temples, it once gave powers to admirals and galactic governors. The galaxy will belong to the faction that can take control of the Dust and uncover its secrets.”

To infinity…

In Endless Space Collection, you guide one of eight civilizations. You carve through the galaxy on a conquest, either by brandishing the blade, or through diplomacy. In the game, you can trade or discover ancient artifacts.
