Calisto Protocol Hits $7 on Amazon, Stock Wanes Fast

The Calisto Protocol, a 2022 survival-horror game by Striking Distance/Krafton, is on sale for $7 on Amazon (not Microsoft Store). The price has fluctuated as Amazon restocks the listing, and stock could run out again soon. At $7 this is the cheapest way to play on Xbox Series X right now since the game isn’t on Xbox Game Pass; it normally retails for $70 and offers about 10–12 hours of gameplay.
