CS2 Reference

Entity schemas, protobufs, console variables and content tables, generated from the shipped Counter-Strike 2 binaries. Every page on this site is projected from one CS2OpenDev-SchemaTracker artifact set, so the offsets, message shapes and console tables all describe the same game build; community annotations from this repository’s overlay files are layered on top where they exist.

Start here

Plugin developers

Server and client entity schemas, with offsets, field types and the inheritance tree, plus a reverse index of which classes use a given type.

Demo parser authors

The wire protobufs a .dem file and a live connection are built from, plus the network message and game event registries that key into them.

Server operators

Every console variable and command this build registers, and the game modes and maps a server config chooses between.

Modders

Item and kit definitions, collision groups and the surface property tables that drive footsteps, penetration and impact effects.

Codegen consumers

The same data as flat, machine-readable JSON and .proto files, meant for a build step rather than a browser.

How pages are generated

Every reference page here is rendered at build time from one SchemaTracker artifact set; nothing is hand-edited except a per-entity overlay layer that adds descriptions, notes and warnings on top of the raw binary data. If you want to contribute an annotation, read the overlays README on GitHub.
