The reason STALKER 2 was released on Xbox Series and PC, bypassing the previous generation consoles, is quite simple. According to the PR-manager of GSC Game World Zakhar Bocharov, the game simply cannot be launched on the consoles of the previous generation.
STALKER 2 is a next generation game. It cannot be played on Xbox One and PS4.
The game will definitely launch on the PS5, but the studio has no plans to release it on the Sony console. At least not yet.
There are currently no plans (to release the game for PS5). We are focusing on the production of the Xbox Series version as we saw several key opportunities when working with Microsoft.
One of such opportunities, Bocharov called Game Pass. The prospect of STALKER 2 appearing on Game Pass on release day has attracted developers.
The release date for STALKER 2 is still unknown. The game is expected to be released before the end of 2021.
