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.

M1A1 Tank

Thanks for your support in making all of this possible!

Until next time,

You guys should team up With the BM team.
Seriously.
I think a total overhaul of all the original Half-Lives would be perfect.
Isn't there another team working on Opposing force source?
You three teams should get together
The original Half-Life going to source is a worthy cause after all.
It would be nice if you all worked together =)
and made it the best it can be =D

What's done is impressive ,however the team must be huge......
The whole black mesa incident is too complex and large.

Looking forward to the mod and the next update (a little hypocritical coming from a Black Mesa developer I know lol), but I genuinely look forward to having a run around :)
