How many GB is Project Three?

2 GB

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

Leave at least 8 GB free: games need headroom to unpack updates.

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

Project Three is a fan-made sequel to Half-Life 2: Episode Two, inspired by Mark Laidlaw's Epistle 3 script, which was adjusted and refined by fans to fit the cooperative story campaign.
