Hazard Course features a complete re-creation of Half-Life's training level, including new dialogue and voice acting, HD models, textures, and detailed environments.

Developed by PSR Digital, Hazard Course is an add-on for Black Mesa centered around a completely new take on Half-Life's training level, "Hazard Course", featuring 6 maps, a wealth of new models and textures, an expanded introduction and outro sequence (based on the sequence exclusive to the PS2 version of Half-Life), and tons of new dialogue from the entire Black Mesa voice cast.
