How many GB is Mayak?

3 GB

That is less than the typical Adventure game, which needs about 5 GB.

Leave at least 9 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

Hard-sci-fi side-scrolling VN about first contact, love, and a prime-number countdown. You are a young astronomer researching a newly received signal from a distant star. Unravel an alien mystery — and fight to save the one you love.
