The foundation of the SR mod ecosystem — a powerful core framework for Call of Duty 4 providing the libraries, utilities, and systems that all SR mods are built on. SR-Core handles everything from low-level engine access and database connectivity to player movement, HUDs, game modes, and server administration.
At the heart of SR-Core is a callback-based event system. All modules are fully isolated and communicate exclusively through events, keeping the codebase decoupled and extensible.
180+ built-in commands covering graphics, minigames, maps, players, and debugging. Servers can define admin roles and VIP tiers with granular permission control, and custom commands can be created and registered.
Leaderboards, personal bests, ranking, match systems, and voting are all built in. Anti-cheat dedicated coverage for elevator exploits, lag switching, and low FPS abuse.
Every map and mode keeps a recording of its current world record, watchable directly in-game. Playback reproduces the full run including entities and chat messages, with slow motion and rewind controls to study any moment in detail.

Every player can tailor their look from top to bottom — weapons, characters, knives, knife skins, gloves, sprays, and trails are all individually customisable and visible to the whole server.
A scripted menu system allowing custom entries and actions to be registered and triggered in-game. Modules can hook into the overlay system without modifying core code.
SR-Core exposes an API for mappers to integrate speedrun, deathrun, battle royale, player, maps and other game mode functionality directly into their maps. A full usage guide and map testing tools are available in the SR-Dev repository.
