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.

I love gamma and I've been doing what i can to make sure everyone can play it. it's super dope to see something that so many were passionate about get some backing. Now as long as you have stalker two or Call of Pripyat, you can just download and play gamma without any issue!
I have been playing games for 40 years, since i got the NES when i was 5 years old, ive played all the best FPS games over the years for both PC and Console. And i can tell you with my hand on my heart that this is THE best FPS experience i have ever had. What allways wins me over with GAMMA is how the progression works, you have to work and earn eveything, nothing is free, its misery. This makes it so that when you finally get rewarded for your hard work the reward feels incredibly good!
That AK-47 you just used 5 hours to fix up is not just a random gun, its YOUR BABY and your gona cheerish it for the rest of your playthrough, even when you get a better gun, your gona place it your display case.
This game does not hold your hand, it wants to kill you, you are not the hero, you are 1 of many who is just trying to make it to the next day. Its this respect for the player that makes me come back every new big patch
You want pain and suffering in a form of a game, i got you.
Now 10x easier to install and enjoy the chest pain produced by chimera jumping at you from behind.
10/10
It's a challenging game, full of survival features that will keep you playing, even outside of the main narrative (if you enable it at all).
If you're just getting into it, read all the notes and tutorials in the PDA, as they'll help you get your feel settled.
