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

The road was really rocky, and it seemed it wouldn't ever arrive, but we have finally in our hands a version stable enough, for the closed beta to begin.

New HMG1 model / Driveable Zuk van

In the case someone missed our previous article, here’s a recap on what are the goals of the closed beta:

  • Expose any exploits or critical bugs that were overlooked during the internal testing, and fix them
  • Restore the community-driven infrastructure of servers, public bug reporting, our official map database, and more.
  • Generate updated wiki, tutorial & guide information for modders and server operators for the new version.
  • Provide us with a larger pool of players to draw input from, as we work on the balance and polish of our content, leading up to the public release

Diving / Improved Points Transfer feature

While we are beginning to select the first candidates from a closed pool, there are three tester roles, which can be applied to by the public freely:

  • Server Admins:
    With a focus towards current OC 1.35 server admins, we want anyone interested to host, on having access into the new Steam version, so they can start preparing their servers and at the same time, give us feedback about potential issues and improvements needed

  • Translators:
    While OC always had a Japanese translation, we would like to expand the number of languages offered, especially now that we are on Steam. Users who are already present in our community, and that have already translated for other mods, will be favoured. Due to the sheer number of strings, it is recommended to work with another or as a team, per each language. For a list of current languages and who are working on them, please check our Trello

  • Community Modders:
    With a great interest towards mappers, we want any “battle-hardened” modder to participate in, so they can tell us how they are finding the new version. Those familiar with creating stuff for the mod, will be favoured, as they might know what to do, to adapt old community maps for the Steam version if they want to. And if they can lend us a hand by writing / updating the Wiki and guides, even better!

We don’t have a fixed range of dates of how long should last the beta, and when the preparatives for the release should begin. Hopefully, we will not face many issues during it, so on the worst case scenario, it doesn’t take us longer than half a year to actually begin the final countdown towards the release.

Umizuri / Stitches 02

Unfortunately, not everything is good news: Early this year, we had to say goodbye to KittopiaCreator, as he retired from Source modding, due to several real life issues affecting him. We are thankful for his great work done on the mod, and we wish him the best of luck in life.

This meant that our development speed decreased even more, although thankfully he completed his tasks before leaving, so we weren’t impacted much by his leave.

However, this could complicate things at a later time for the release. As a such, we are especially seeking new programmers to aid us with tweaking and solving issues found during the beta. Of course, we also have other open positions, like level designers or 2D artists. And one time contributors are accepted as well.

Interested? Head over to our application form page!



New HL2 Bullsquid model / Ping feature

We hope that things goes smoothly from here, so we will keep all of you communicated about the progress through our Discord server and the Steam store page. With luck, we shall release this year!

Happy Pride month!

Now let me get one thing clear, does this mod require the original half life 2? Or is it non-steam? Please do answer as quick as possible because I am in such a rush to play with my friends.

It actually does not require base hl2! Surprising right? But you do need source sdk base 2013, which is free of course. So OC is completely free! However, some maps may require the hl2 episodes or DOD, but that's only a few, none of them actually require HL2 itself.
