The definitive survival overhaul for the Zone.
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.
