The Callisto Protocol

In this narrative-driven, third-person survival horror game set 300 years in the future, the player will take on the role of Jacob Lee – a victim of fate thrown into Black Iron Prison, a maximum-security penitentiary located on Jupiter's moon, Callisto.

When inmates begin to transform into monstrous creatures, the prison is thrown into chaos.

PC gaming spans over four decades, from early DOS titles to today's massive Steam and digital-storefront libraries. Because "PC" covers everything from 1990s CD-ROM releases to current AAA titles, it's the single largest platform by game count on Gamevaro. For collectors, PC gaming splits into two very different worlds: physical big-box releases from the 1990s and 2000s (increasingly collectible, especially complete-in-box with original manuals and inserts) and the modern digital library, which Gamevaro tracks for portfolio and spending purposes even though it has no resale market.

Gamevaro tracks The Callisto Protocol for PC with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.

Adding The Callisto Protocol to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This PC release dates back to 2022.

No market sales have been tracked yet for The Callisto Protocol — this could mean it rarely changes hands, or simply that Gamevaro hasn't recorded a sale for it yet. Be the first to add it to your collection.

Condition matters a lot for collector value: loose (cartridge/disc only), complete-in-box (CIB, with original packaging and manual) and factory-sealed copies are tracked separately because the price gap between them can be significant, especially for older releases.
