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!

What are you doing to improve that's making the whole process take a long time? I'm only interested because your team seems to be taking on the same legacy as the Black Mesa Dev team. "...Take forever to finish... Doesn't live to expectations..." I'm sorry, it's just the one of the shortest parts of the Half-Life game can be expanded upon, but do you really thing it's necessary to go 'all out' with it? Just a thought, I could be extremely inaccurate.

Thank you for building high expectations of us then assuming we won't live up to them. I'm sure that's a great way to enjoy mods, or anything.

We've said it before, and I'll say it again: Modding is not our job, we have things to do. College, jobs, a life outside of mod development. We don't always have large amounts of free time, and when we do, we may not want to spend every last second of it working on HC.

Lastly, what's with the new wave of people thinking HC isn't worth remaking? Summer?
We're "going all out" because we want to. It's fun for us. We enjoy creating things and working together. Nostalgic, too. Cap on that there seems to be plenty of people liking what we're doing, that's all reason enough. No one's forcing you to wait or play, so I don't get why you're questioning us.

Can't agree more with Crypt here. Personally, I want to see what can be done by remaking that tutorial level, mostly if it's made in a coherent way like the rest of the remake of Black Mesa (and so there's a lot of space to work with the training course).

Is it worth doing all this just for 1 map?

There are six.

Would you rather us not do it at all?

Sigh. Okay, this time I'll just spell it out.


Give me a chance to make stupid tree puns in front of a thousand people and dammit I'm doing it.

Yep, some areas will be extended, there's some new rooms, etc. One of the images we posted is an overview, and while it's a tad outdated, it can give you a decent idea of new areas.
