For those who bought the game through GOG, Steam, Epic Games Store, or the PlayStation Network, Mind Control Delete will simply show up in their library within a few days after launch. Xbox One owners should receive a system notification containing a voucher code to claim the game. For those who bought the game from any other store or platform (Mac or Linux), they will need to email Superhot Team a copy of their receipt to get a voucher. There are a couple of caveats, however.
First, this offer is only good for those that bought Superhot, not to be confused with Superhot VR. Users who obtained the game through a giveaway like PlayStation Plus or Xbox Gold freebies or any other promotion are not eligible. The press release says it has to have been "[legally acquired] and not as part of a free giveaway of any sorts [sic]."
Second, the offer is only available to those who purchased Superhot before Mind Control Delete's release date of July 16, 2020. That means that users have about a week left to pick up the first game to be eligible. Superhot usually sells for $25. Currently, the game is discounted 60 percent on GOG, EGS, Steam and the Microsoft Store. So spending $10 now gets you both titles on PC or Xbox One. It is full price on PSN.
