How many GB is Halley2061?

15 GB

That is more than the typical Role-playing (RPG) game, which needs about 6 GB.

Leave at least 23 GB free: games need headroom to unpack updates.

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

This is a space sci-fi survival and building game. You take on the role of a retired astronaut on a top-secret mission to the Halley’s Comet. Resource and time management will be key to your survival. Will you wisely use limited supplies to build your own space base and achieve self-sufficiency?
