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. 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, but now that we're in Beta, development is going stronger than ever!


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


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

Beta Update

1 month ago News 4 comments

Hey! Long time no see.

Okay, so it hasn't been that long, but definitely long enough that some stuff has happened! Beta is going pretty great. We've been Hammering out our bugs, making our props prettier, fixing our choreography and having some great recording sessions with our voice actors and actresses. Really, these guys are great, and they really bring the course experience together. We can't wait for you to hear them!

Amidst our polishing, general progress and whatnot, we've also gone ahead and set up a page over on Facebook. If you're interested in more frequent smaller updates (and you'd better be!), go ahead and follow us over there as well. It's a great time. We'll keep you guys posted, can get in touch with us, all that good stuff.


That's the brunt of our news for now. As a parting gift, have another peek at some of Beta's fruits. Remember this?

Well, JeffMOD and Crypt teamed up for Beta, and blew it out of the water.

Range Canal

That's all for now. We'll try not to be a stranger, and will have more updates for you soon. See ya then!

Hey, I know there are probably many experienced mod developers passing through here so I thought I'd bring this up:
I don't know if any of you've heard about the (now dead) mod hazard team or decay: source. It passed away some time ago ,and I hope others share my sadness as they read this, so I was wondering if anyone on the hazard course dev team is interested in reviving it? Is anyone actually still interested in the mod at all?

That was a sad December day for me!
Personally I'd be interested in giving it a shot once I'm done with my current projects. The team however doesn't have any plans *at the moment* for anything. HC is our focus until it's time for release.

Pretty good, thanks. Most of the changes we've made recently are entity work and minor tweaks, so sadly we don't have much new to show you in the way of media, but hopefully we'll have something substantial enough to warrant new shots or a nice video sometime in the nearish future.

Here is a partially rude comment on your work, annoying, isn't it?
Leave my projects alone or be nice. Read the TOS.

Um, you are?
I am about 100% sure you've got the wrong page. No one that works on this mod has been rude to you, so you can keep your vindication to yourself.

Yes, I have. I looked through your mod's media and comment sections before replying, and no one on our team has done anything rude towards you. BoxNoob hasn't been on our team for months, and even if he was, he's acting of his own accord, not our team's. Personally, I feel it's very cad-like to try and bring the argument to our page due to some ambiguous comments that could be interpreted as rude. You're problem doesn't lie with us.

Yeah, actually I did, because no newer model does that. I think it's because of the old disc drives and how often they fail.
