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,

Would you consider letting the player explore Barney's dorm before entering the tram?

While it sounds awesome, it would be a lot of extra work for something that has no real positive impact on the game. The introduction is already long enough, if we make it any longer, game would suffer. Not good especialy for repeated playthroughs.

Then I suppose I'll just use noclip to get a longer look the second time I play.

So this mod will include it's own version of Uplink? does that mean you get to play as Freeman with the HWV?

We will reveal more about Uplink at some point. While the main point will be the same, we aim to intergrate the storyline better to the story and make it cannon, at least in terms of our universum. This may bring some changes you wouldn't expect. But later about this

Put it on Greenlight! Both Operation: Black Mesa and Black Mesa itself have already been there, why can't you?
