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

Unofficial mountfix

News 8 comments

Hello everyone, we’d just like to inform you that our community member jfm created an automatic mountfix installer, big thanks to him!


Please note that it is not created by the OC team and we do not take responsibility for any damage it might do to your system.

It comes in 2 versions, one with a full OC installer included and one with just the mountfix.
Please make sure .NET Framework 4.5 is installed and you're running at least Windows Vista, XP is not supported.

Downloads:

Zipped versions, for those that want them:


So how does it work and what does it do?

  • Before installing, make sure you have SDK Base 2007 and all the games you want to mount installed and fully working in Steam.
  • Now, you either just run the full installer, which will execute the mountfix.exe once it’s done installing OC, or
  • place the mountfix. exe in your existing Steamapps/Sourcemods/Obsidian folder, run it, either type "client" or "server" and hit enter.

The server part installs and configures a basic server config setup for first time server admins and requires a login.
The login is required for SteamCMD and is NEVER stored.

For more information and credits, check this Readme.


Please note that the mountfix can take a long time to complete and it may seem like nothing is happening at all. Don’t close the window, this is normal! The window will close once it’s done.

What the mountfix does is it first scans for your installed games, extracts the content from their depositories and then creates symlinks in your steamapps\common\Source SDK Base 2007 folder.
This process is very hard disk-heavy and thus can take a long time to complete.

This also doubles the disk space taken for each installed, mountable game since the files now exist twice; once in the normal Steam depositories and once as unpacked files which OC can read.


We are still working on a proper hotfix, but until then, this is a good stop-gap measure if you or your friends want to get into some OC action right now.

Wow, now I remember the days of the "Deady School Bus" (remember that map?), and the harvest gamemode. This really brings back my memories which I experienced when I was 9...

I still love, how when they started with the Devblog, and it had some really fancy stuff on it, valve decided, let us break everything...
Obisidian Conflict should replace Synergy, it has everything and much more!

More =/= Better.
I like Synergy because it's clean and focused. I don't need a bunch of extra re-skined weapons (that I will never use) or an MP3 player to beat the Half-life campaign. It also has a workshop and better support for co-oping other HL2 mods.
However I like Obsidian for their unique maps and games. I played a lot of harvest and the fishing map back in the day, and had a great time with it.

OC devs seem to have real life in the way, and the Synergy devs could spend more on their project, so that's why they got on Steam, simple as that. It's not about Steam picking sides.
It's not Valve's fault that the mod broke, that's a childish way of thinking. They are not going to leave vulnerabilities in the game code just because it might break a few mods, when the mod devs can fix those.

And this constant comparison is pointless anyway, both mods have it's merits and weak points, both are free and you can play whichever you would like at any time.
Yet people are still like: "Oh, all of Team A's hard work is ****, just because I'm in Team B"
This is just artificial and pointlessly creating a divide in the community, so how about we just stop it.

Compile it for HL2EP2 and then move the model and textures over to OC, if it's a playermodel make sure you got the animations set up in the qc n stuff before compiling.

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