The Subject

Short description

You have been taken prisoner and sold to a deep space testing facility. Upon arrival, you are fitted with a device forcing you to participate in their experiment. Released into a massive complex, the dark halls wind around testing rooms and conceal pieces to puzzles. There is no option but to comply.

Review count and SteamSpy's owner range agree well enough to narrow the estimate down to this band. Multiplied by the $4.99 launch price — there is not enough price history for this game to weight the copies by what they actually sold for. Before Steam's cut, VAT and refunds. How these numbers are calculated.
