Welcome to our first media update this year!

Read Full Article.

Multiplayer Beta Release Q1 2014 Cancelled


Our plan to bring you the multiplayer beta of Operation Black Mesa early this year didn't work out, regrettably. Several factors and circumstances forced us to completely keep it under the hood until further notice.

Multiplayer Progress


Multiplayer will feature classic maps such as Yard, Crossfire and Boot Camp as well as brand-new ones like Deptcharge and Gambit from day 1.
Currently in development: CTF mode and weapon placement.

Depthcharge

Singleplayer Campaign


Development is running smoothly; those NPCs aren't going to animate themselves though! If you're interested in joining our team, check out the jobs page where you can find all positions currently open. We look forward to welcoming you on board!

Pit Worm's Nest

Remember Guard Duty (Blue Shift: Source)? We're making solid progress here too:

Living Quarters Outbound

OBM: The Video Game?


We've been given the option of developing our projects as full indie titles to be sold on Steam!
This opens up a whole lot of attractive possibilities to consider; however no decision has been reached yet as to this matter.

Alien Controller

M1A1 Tank

Thanks for your support in making all of this possible!

Until next time,

You shouldn't have put GMan in there. He wasn't involved with Barney, and the fake voice just sounds silly. Other than that it's a great mod so far.

Congratulations! But I must re-emphasise the need for "classic" HECU soldiers- for consistency with Black Mesa Source and Operation Black Mesa. Maybe you could make it an option to use BMS/OBM's models. I understand you're going for realism, but since when has Half-Life ever been realistic?

That's kind of besides the point. I'm saying, you should allow the option for HECU soldiers rather than "real" Marines so it's true to the original game.
