Black Mesa: Hazard Course is an add-on for the well known Source Engine mod, Black Mesa. Using Black Mesa assets as well as much of our own custom made content, Black Mesa Hazard Course will feature a complete re-creation of Half-Life's training level, including new dialogue and voice acting, HD models, textures and detailed environments.
