xlibs & AlifePlus
Damian Sirbu · Updated 2026-04-15
xlibs is a modder's toolbox for STALKER Anomaly. It replaces raw X-Ray engine calls with safe, tested Lua wrappers — squad operations, smart terrain queries, entity identification, an event bus for mod-to-mod communication, MCM config, PDA messaging, logging, profiling, and more. If you're writing a STALKER mod, xlibs handles the engine so you can focus on gameplay.
AlifePlus is a behavior framework built on xlibs. The Zone is full of events — squads move between locations, NPCs die, stashes get looted, massacres happen. AlifePlus classifies these into causes and routes them to consequences: nearby stalkers investigate a massacre, bandits ambush a stash looter, a faction sends a revenge squad. Mods register a predicate and a handler; the framework handles throttling, protection, rate limiting, tracing, and lifecycle.
Right now every alife mod in the Anomaly ecosystem hooks the same engine callbacks independently, implements its own throttling, and fights other mods for control of the same squads. xlibs and AlifePlus exist so that mods can share one pipeline instead of reinventing it. Any mod author who wants to build on these systems is welcome — see the usage guide or reach out directly.
Both projects are published under the PolyForm Perimeter License. Addons, integrations, and modpacks are encouraged with visible credit.
Within weeks of publication, three derivative mods appeared on ModDB by two different authors. SISKI ALIFE (by qkff99) cloned xlibs's internal infrastructure (event bus, callback factory, AP bridge) while xlibs was still under a proprietary license. SISKI Nano (by the same author) repackaged the same patterns as a single-file drop with no version control or attribution. AlifePlus SISKI Synergy (APS) (by forTheMonolith) cloned AlifePlus's architecture iteration by iteration, feeding internal design documents to an AI code generator and shipping the output as a "synergy" mod. The patterns used by all three exist nowhere else in the entire STALKER modding ecosystem.
All three were filed against on 2026-04-05. ModDB removed all three on 2026-04-19 after a thirteen-day review. Only the SISKI author appealed; the appeal was rejected on 2026-04-26 after a further week of review, with settlement terms imposed (apology, no-contact undertaking, mod rework, mod rename). All three mods remain down.
The "synergy" disguise has not stopped. New mods using the same pattern — AI-generated clones of AlifePlus internals marketed as compatibility add-ons — continue to appear on ModDB. One example already live at the time of writing: "AlifePlus SISKI Compatibility Patch". The reports below document the original three; the pattern is what to watch.
If you are here because someone linked you one of these reports, start with the one that was linked. If you are a mod author interested in building on xlibs or AlifePlus, start with the usage guide instead.
Getting Started
Code Theft Reports
SISKI ALIFE — Code Theft Report
The SISKI author admitted on Discord that he fed AlifePlus source into an AI and "made an identical one." Deleted AI plans recovered from git history prescribe AlifePlus's architecture verbatim. Event bus, callback factory, and AP bridge copied within 5-7 days of source publication. The bus clone is the only named-subscriber pub/sub system in 2,161 GAMMA script files.
SISKI on ModDB
SISKI Nano — Technical Analysis
A single-file derivative by the same author, distributed without version control or license. Shares the same architectural patterns and AI code markers as SISKI ALIFE.

AlifePlus SISKI Synergy — Architecture Cloning Report
AI-generated mod that copies AlifePlus's internal architecture, conventions, personality system, and feature designs. The consequence template, internal API calls, and terminology it uses exist nowhere else in the modding ecosystem. Author promised to take it down, then re-uploaded on a new page. Still depends on SISKI (stolen code).
