Install Method — PlayBound installer
Requires a working Anomaly 1.5.x install first (PlayBound Anomaly — Standalone edition). Then open the official Grokitach/Stalker_GAMMA Installing-GAMMA wiki and run the G.A.M.M.A. launcher — it pulls addons from ModDB/GitHub automatically. Large download; SSD recommended.
