How many GB is Halcyon?

3 GB

That is less than the typical Shooter game, which needs about 8 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.

A pixel art challenging sidescroller shooter set in a future inhospitable version of Earth. The year is 2506. A vestige of humankind, you’ve been sent to Earth on the faint hopes that you will find more than the corpse of a once hospitable planet. Instead, you find a landscape blooming with lush, mutated new life.
