Average players from our own counts over the 7 days before each sale, while it ran, and the 7 days after, kept clear of the sales either side. Steam’s big seasonal sales lift the whole store, so not every rise is this discount alone. How we count
Two detectives, one deadly experiment, a race against time. Each player only has one half of the puzzle. In this 2-player co-op puzzle game you can survive the parallel experiment only by working together.
