Obsidian Conflict is a cooperative multiplayer modification set in the Half-Life 2 universe.
It features a large amount of new gameplay features on all-new maps specially designed for the mod with focus on cooperative gameplay, as well as over hundred user-made maps following the same formula.

In addition to that, You're able to play through vanilla Half-Life 2 all the way up to Episode 2, as well as experimental support for cooperative Half-Life: Source play.

Key features:

- All Source engine Half-Life series games playable in co-op online (Half-Life: Source, Half-Life 2, Lost Coast, Episodes 1 & 2)
- A large set of included custom maps, some in the form of classic combat & teamwork puzzles and others offering extraordinary new gameplay experiences such as cooperative farming and fishing
- New weapons, including dual Uzis, Medkit, Sniper Rifle, the Alyxgun, the Tau Cannon, deployable Manhacks, as well as support for scripted weapons allowing use of weapons from Counterstrike and Day of Defeat Source
- New NPCs, including many from the original half-life such as a fully-functional ichthyosaur, as well as a working mortarsynth from HL2
- Special merchant NPC and related entities, offering gameplay where players can spend points from their score to purchase weapons and map-specific objects
- Many co-op related features, such as a server-side lives system, hud waypoints, player locator, attention & medic calls, and map objectives, as well as players' inventory carrying over between level transitions
- Great support for community mappers, including features like the mapadd system to easily edit existing maps without having to recompile them, as well as tutorials and prefab examples for all of OC's new entities and features
- Support for custom playermodels and custom colorizations on weapons and hud elements

We've been quiet for too long again, heck, we almost could have reused the news post from last Christmas by now.

So, to break the silence, we present you the first one of our "Dev Blog" Videos. Those should allow us to give you guys a more constant stream of news posts, since we can show a lot more WIP and experimental stuff that way without focusing too much on full-fledged, pretty looking news.

Remember most of the stuff shown is more or less work in progress and thus subject to change, but feel free to tell us what you think still!

This mod really need update, because more updates of HL2, episodes and Source SDK Base 2007 from valve -> more bugs in mod and compatibility issues.

Yeah, I had that when trying to run any mod. I fixed it by deleting everything inside the Steam folder, except for steamapps, downloading the Steam installer from their site, and after running it, choosing repair.

I assume you've fixed it or don't care by now, but incase anyone else stumbles by with the same problem, the above should sort it out.

you guys should release something.

Not like the next version, but like another hotfix to try to keep the playerbase stimulated.

Nice option, almost perfect co-op mod and with a lot more options than Synergy. You should try it. :D
