STALKER Anomaly Co-op Mod — xrRazom

xrRazom 1.4 (3 Oct 2026) targets Anomaly 1.5.3 and GAMMA. Steam still expects Call of Pripyat on every account in the session even though you launch Anomaly. This is not xrMPE's CoP campaign. Wrong Anomaly minor (1.5.2 vs 1.5.3) fails before the Zone loads. CoP missing on a guest Steam library looks like a generic Steam auth error. ## Steam still asks for Call of Pripyat The documented Steam path still wants CoP on every account. xrMPE is the CoP folder, not Anomaly. ## Anomaly 1.5.3 / GAMMA host world

• Anomaly 1.5.3, three storylines.
