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!

Well, I can honestly say that I am broken up by the fact the MGO/Dissent/Latitude shut down after SO long. Best server I can say honestly, from the custom credits system, to holstering system, from buying custom weapons...OC won't be the same without them :(.

I'm probably gonna stop playing, considering the most populated server is a ****** anime-fanbase one who yells at anyone under the age of 15 so loud that their mics static out.

I was the last one to donate to the server.
I think a lot of people found Latitude/Dissent to be synonymous with Obsidian Conflict (including myself).

which are you talking about? I'd guess Xeno's?
because then it's not really the most populated one.
The official one has nearly a constant minimum 3 players base (enough to play in coop since it's not about quantity but quality)

Now, is the medpack bugged or am I just unable to heal myself with it?

It's a coop mod. It doesn't heal yourself so you can't solo-bumrush maps.

It only heals other players, yes.

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