Black Mesa: Hazard Course is an add-on for the Source Engine mod Black Mesa, featuring a completely new perspective on Half-Life's Hazard Course. The Black Mesa Hazard Course will feature:

-New HD models & textures
-New dialogue & voice acting
-New maps and detailed environments
-Expanded intro, similar to Half-Life's PS2 version

Since this is a community project, we welcome people to help out in any way, from suggestions to fan-made content. Currently we are looking for people to fill these positions:


Any suggestions (within reasonable bounds, of course) are also welcome from anybody!

Media Policy

Remember that great mod, Black Mesa? Anyone familiar with the Black Mesa mod and its agonizing development cycle may remember long periods of media blackout. Since this is a community project rather than a full-fledged modding team, we are pleased to announce that, unlike the original mod, it will be our policy to strive to be as open as possible with the development process!

That's right. Expect to see half-finished areas, heavy WiPs and lots of orange and gray "dev" textures!

We do, however, announce this policy with a disclaimer: We hope that all of our followers will try their best to be as mature as possible, and realize that due to the open nature of our development process, the vast majority of media that will be released will NOT be fully representative of the final product.

This can be a good thing! It allows YOU, the followers, to give feedback early, so that we can make easy changes to give YOU what you want!

So criticize away! Just keep it civil!

Is this mod dead?

If you're reading this, then no. There is no point in letting a project die without notice. If we were to die, we'd be sure to let you know, however we have absolutely zero plans on doing so, and the mod is currently going strong.


Black Mesa: Hazard Course requires:
-The free Source SDK Base 2007
-Black Mesa

Thank you. Have a very safe, and productive day.

Greetings, fans, players and modders alike!
Happy holidays from the Hazard Dev Team! Merry Christmas! Merry Coursemas! I'm so sorry.
As much as we hate to keep you from your candy-cane shanks, we've got some paragraphs and goodies for you.

We've been in development since shortly after Black Mesa's first release. That makes us a bit over 2 years old. In that time, our members have learned a lot, and we think it shows. Just look at the comparison images above!

While we're not exactly stoked at our development's time span, we do think that because of it, the Hazard Course that you get to experience on release will be worlds better than what you would have if some silly team members' early estimates were correct.

As we enter Beta 1, the course is prettier, longer, and overall more fun, and the end is slowly getting easier to see. At this point, our largest hurdle is choreography. We remain without any actual choreographers on the team, and we can't make use of our neat little script or voice actors without one or two. That's a huge slowdown. If we can get that sorted, we'll be ready for a release in 2015 for sure. Can you guys help us out with that? If you're a Source Choreographer or know one, why don't you check out the job page and send us an application? Sort of important!

That's all for this update, we wish you a Happy Coursemas.

Wait, one more thing.

Over the last few weeks we posted some extra shots over in our thread on the Black Mesa Forums. As a final holiday gift to ModDB, why don't you guys check them out? Hope you like them!

Just thought I'd update here: There's going to be a new menu option. None of the chapters will be effected.

Well if your taking off the wall suggestions, you could always have the AI go batsh*t crazy and start trying to kill you a-la-glados along with a couple of secret areas or maps. :-p

Anyway, looking forward to the final product!

There wasn't an AI in Black Mesa, just a VOX system that relay and announce message from computer

Good luck guys, but be careful !

Take your time and don't try to just copy the original Hazard Course. Like the BM Team and the ST Uncut pack, try to be creative. Don't hesitate to totally rebuild a map if necessary.

It will be a pity that you do this mistake as the Black Mesa : Uplink leader did with his mod.

There are already some extensive modifications to the levels. We have some pretty cool and/or pretty fun things up our sleeve as well. If we can get everything working as planned, I should think that this has the potential to end up being more than a simple remake. ;)

I am reassured !

Of course you're not the same team that the one of ​BM : Uplink, but me and other fans became nervous about the others extension of Black Mesa. Particulary since Uplink is done (And also since we heard about "The Shift" and "Black Mesa : Blue-Shift", two mods for Blue-Shift with one guy only for each, when there is already Guard of Duty since some years).

Uplink is definitely a big deception, and has (exept for one or two place) the same maps than the original Uplink. And I don't talk of all bugs and problems that this mod adds to Black Mesa.

So that's why I warning you guys. I just don't want to see the same potential be destroyed a second time. You have all the time that you needed, so take your time and create the best source version of the Hazard Course !
