Metamod:Source

Introduction

Metamod:Source is an API manager and interception handler that sits in between the Half-Life 2 Engine (Source) and a subsequent Game Modification (MOD). It can dynamically load "SourceMM Plugins", written in C++, to intercept, override, and hook Engine and GameDLL API interfaces. It also allows for inter-plugin communication. As a backend it contains SourceHook, a powerful library for safely manipulating virtual table hooks.
