How many GB is Heat Signature?

0.39 GB

That makes it bigger than 15% of Simulator games we have measured.

The median Simulator game needs 2 GB; the largest tenth start at 20 GB.

Leave at least 6 GB free: games need headroom to unpack updates.

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