How many GB is Project Sphinx?

4 GB

That is more than the typical Platform game, which needs about 2 GB.

Leave at least 10 GB free: games need headroom to unpack updates.

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

In this first-person puzzle-solving game, you're a robot with a mission on a space station. And like any great robot, you're going to have to explore, teleport and ricochet your way around the base, in which each room and corridor is a puzzle to solve.
