This is the Homeworld prequel made by the same people that did Homeworld Remastered.
Homeworld - Deserts of Kharak official page.
Having said that, Scott Manley's Let's Play has convinced me that I want to play it. ~grins~ Oh, I will LOOSE, but I will have fun doing so.
They just massively discounted both DESERTS OF KHARAK and HOMEWORLD REMASTERED. They also released a major new update for DESERTS OF KHARAK which fixes the last few remaining bugs and adds the "tactical pause" feature from the original HW games.
DESERTS OF KHARAK is superb. I strongly recommend it.
