S.T.A.L.K.E.R. Anomaly GAMMA (Grok's Automated Modular Modpack for Anomaly) is a hardcore, curated survival experience built on top of S.T.A.L.K.E.R. Anomaly. Designed for stalkers who want a deeper, more immersive journey, GAMMA integrates over 400 hand-picked mods into a single, finely balanced package. No manual modding required, just install, survive, and adapt.
Built for Survival. Tuned for Immersion.
True Progression – every piece of gear must be earned. Travel deeper into the Zone to unlock better weapons, armor, and tools, but be prepared for the deadliest threats it has to offer.
Overhauled Economy & Looting – no more buy-sell comfort loops. GAMMA removes easy trading and randomized stash rewards, forcing you to scavenge, craft, and survive through intent, not convenience.
Body Part Damage & Medical System – injuries now target specific limbs. Managing bleeding, pain, infection, and exposure requires medical planning and a full survival kit; bandages alone won’t save you.
Artifact Progression – artifacts must be carefully empowered and combined. Instead of instant benefits, they offer meaningful long-term progression.
Custom UI & Visuals – enhanced menus, immersive shaders, redesigned HUD elements, and improved performance ensure every moment in the Zone looks and feels intense.
A Zone That Evolves With You
GAMMA adapts S.T.A.L.K.E.R. Anomaly into a longer-form, higher-stakes experience. It encourages cautious exploration, smart inventory management, and tactical engagements across a world that’s as deadly as it is dynamic.
With multiple difficulty presets, faction options, and curated progression paths, every run feels different yet always true to the heart of the Zone.
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.

The Mod you’re about to enjoy is the work of passionate fans who wanted to share their love in an even more meaningful manner.

I’m in my thirties and have played more games than I can count. I’m especially fond of shooters and RPGs. I loved the original S.T.A.L.K.E.R. titles and even read the novels. GAMMA is the ultimate modpack that pulls everything together into a coherent, fully realized experience.
Be warned: It’s challenging and unapologetically rough. It looks and sounds incredible. You can get lost in the progression grind, or you can slow down and just immerse yourself in the atmosphere, the tension, and the phenomenal soundtrack. Enemy AI is actually competent - far better than in many newer AAA shooters.
If you want to play a game that rewards learning its systems, respects your time, and constantly generates memorable moments within its sandbox, play this. Nothing else comes close.
Aaand it is going to become even better. It is my gamer dream come true!
This is by far my favorite mod for Stalker but just in general this is my favorite modding experience when comparing it to any other game. If I could only recommened one mod ever, it would be GAMMA.
Let me give you some perspective on monumental work put into this mod pack.
I have been playing this modpack periodically througout the development, and coming from original trilogy, to misery, to anomaly, this is what many people did on their own, finally brought to people by people.
Let me elaborate, anomaly alone is good base, but many players eventually put some addons on. This could lead to a few qol additions, or a few dozen mods, among which some would eventually conflict, and would need to be patched or merged, which is getting into the weeds of programming.
There were some modpacks before(and still are) many of which would be unbalanced or just janky, with guns and attachments not being compatible or gun models looking out of place, and of differing quality.
Grokitach and GAMMA community brought quality and vetting of mods, with specific vision and ease of installation(comparatively).
GAMMA has game development studio levels of quality, with nothing being out of place, and work always ongoing. All this thanks to many addon developers who make stuff quality and Grok and GAMMA for then filtering addons through personal high standarts and community voting, and monumental work being put into adding these to fit in with vision. And all of this is free.
You won't believe how such an old game can look, feel and play this good.
The experience of GAMMA.
Now up front this modpack will not be for everyone.
If you wanted to playe Escape from Tarkov without getting scammed by developeror aimbotted by cheaters, playe this. GAMMA is what tarkov wishes it could be, and you can still get scammed by sidorovich and aimbotted by monolith.
For the rest of potential player, first up, it's free*, so go try it!
If not, this is quite harsh change of pace specially if coming from "modern" shooters or even original stalker games/stalker 2.
The resources are scarce, enemies and monsters are relentless, and you must make the best of what little you have, but if you persevere, the zone is your oyster. You can play and roleplay as anyone, a loner, a bandit, a crazed brainwashed soldier, a peace loving scientist, the list goes on.
You will have the opportunity to work different jobs fro different factions and work on your reputation with them. You will hunt monsters and artifacts alike.
You will have to engage with monumental crafting system to get and keep guns and armors running, and even food and medkits will be cheapest when you are the apothecary.
I can keep going but know one thing:
Friction is what helps this world feel real, along with alive system and the atmosphere and locations. So don't be afraid or upset about failing, just take things in at your own pace!
And finally, I want to thank Grokitach yet again for this, and I am glad I am part of GAMMA community!
