Receiver, a detailed first-person shooter developed as part of a seven-day challenge for PC and Mac, has found its way on Steam. In the game players explore a minimalist world in search of clues to unravel a conspiracy.

Well, if you survive an onslaught of deadly turrets and drones, that is. Taking cues from roguelikes, players must start from the beginning of the world - in search of the evidence that generates in random areas - upon death. Developed by Wolfire Games, Receiver explores the detailed mechanics behind managing and handling a Colt 1911 A1 pistol. Players must load each bullet into clips, manage a safety, compensate for recoil and more.

Receiver can be a tense experience, as I learned in a livestream with the game when it first launched in June of last year. The Steam version is available for 20% off its regular price of $4.99 - priced to move at $3.99 - until May 6.
