Gunpoint snuck in a sale this week and is half off now through Thursday at 7PM ET, making each version just $5, $10 or $15 via Steam or directly from Suspicious Developments. During the sale, $5 is for the base game with the level editor, $10 gets the Special Edition with the soundtrack and in-game developer commentary, and $15 is for the Exclusive Edition, which adds a 40-minute making-of video, playable prototype levels, four exclusive songs and early access to future Suspicious Developments games.
Players who previously bought a lower-tier version of the game and wish to upgrade now have the option to pay the difference and get that next edition. The content is now, essentially, DLC. Gunpoint also added Steam Trading Cards.
Mac and Linux versions of Gunpoint are incoming!
