Obsidian Conflict

About

Obsidian Conflict is a free multiplayer shooter built on the Source Engine inside the Half-Life 2 universe. Players team up to tackle custom maps designed for cooperative play while also accessing the full vanilla campaign from Half-Life to Episode 2. The game includes over a hundred user-created levels that follow the same formula as the official content. You can jump in alone or with friends to fight through waves of enemies and solve puzzles across these new environments. What stands out is the sheer volume of community content available right away alongside the official chapters. This title feels like a natural extension of the original series rather than just a mod. It runs well on PC and keeps the core mechanics familiar while adding fresh objectives for groups to tackle together. The focus stays strictly on getting more people playing together without any unnecessary fluff or complicated systems. If you have a squad ready, this is the place to find them.
