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!

Can you make remake of one of the best mods Half-life: Induction and maybe integrate it with your Hazard Cource?

I'm actually glad to see this being made because it'll give me the nostalgia of playing for the first time. :)

Only reason I didn't take it upon myself to delete this is because I'm kind of impressed. So... Thank you?

Are you going to start in the elevator, or will there also be that introduction scene only found in the PS2 version?
