Microsoft paid more than STALKER 2's full dev cost for Xbox exclusivity
Microsoft's exclusivity deal for STALKER 2: Heart of Chornobyl paid GSC Game World more than the game's entire development cost, the studio's founder has revealed. Sergiy Grygorovych made the disclosure on the OLDBoi podcast, nearly two years after the game launched. Without that deal, he suggested, the game might never have shipped at all.
The deal
Xbox got interested immediately after the first STALKER 2 trailer went online. According to Grygorovych, Microsoft representatives were struck by the trailer's massive reception and had the paperwork ready within a week. The terms secured Xbox Series X|S and PC exclusivity for 12 months, plus day-one inclusion in Game Pass. In return, GSC received a payment that, in Grygorovych's words, covered "more than the cost of Stalker 2" — an undisclosed figure, but one he framed as fully recouping development before the game even launched on November 20, 2024.
That's an unusually candid look at how Game Pass exclusivity deals actually work. Microsoft doesn't publish these figures, and studios rarely do either.
After the exclusivity window
The 12-month timed exclusive expired on schedule. The PS5 version launched exactly one year later, on November 20, 2025, adding DualSense haptic features and PS5 Pro enhancements per AltChar. PlayStation owners who waited out the exclusivity window can now play the full release.
GSC is currently finishing a major story expansion called Cost of Hope. Grygorovych himself has since left the studio and announced a new post-apocalyptic project, S.T.R.A.N.G.E.R. Bermuda SOS.
What this tells us
The STALKER 2 arrangement shows Microsoft moving fast when it spots a title with viral momentum — a one-week turnaround from trailer buzz to signed deal is rare in any industry. For Game Pass subscribers, it's a reminder of how the subscription's day-one lineup gets built: not just through first-party studios, but through up-front payments that de-risk development for independent developers. For PlayStation players, the tradeoff was a year's wait — but the PS5 version ultimately arrived with platform-specific additions intact.
