A Zone That Evolves With You

Community-Built. Curated with Care.
This isn’t just a modpack, it’s the result of thousands of hours of refinement from passionate fans. Designed to be stable, lore-respectful, and challenging, GAMMA is regularly updated and supported via dedicated Discord channels and install tools.
Anomaly was just the beginning. GAMMA is the test of your true stalker instincts.

Slop. Why would GOG promote this?
The modders should be ashamed, the people who made this are disrespecting the legacy of STALKER by doing this.

The Most Overrated mod ever.
Extremely overblown. Strips most of what made stalker stalker in favor of turning the game into a poor mans Tarkov to be enjoyed by keyboard commandos. Used to be free for years now GSC requires you to own the classic games which is their right and in some ways I think it should have happened earlier but doing this to essentially profit from people wanting to play mods while Stalker 2 is still very broken seems kind of scummy. I've owned the OG games on here since 2016 too, the whole thing just seems scummy.
