Hazard Course

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.

This workshop item also includes the Five Nights at the Hazard Course bonus add-on. Originally built for our 2015 April Fools' joke, Five Nights at the Hazard Course is an unofficial minigame set in the Black Mesa Hazard Course, based on the horror game series by Scott Cawthon.

To install this add-on, click the "Subscribe" button above. Steam will automatically download and install the content. You do not need to extract any files or launch any batch scripts.

• When running in the old game UI, custom localized text strings are not displayed properly due to the way the engine mounts content.
  
• Sounds in the Fire Room (including explosion sounds and some voice lines) sometimes don't play.
  
• Observer scientist PA voice lines can be unexpectedly loud when speaking responses to player actions.
  
• In the transition room directly after the suit silo, there's a slightly misaligned red pipe model on the ceiling.
  
• The player can get stuck in the second and third red valve wheels in the Fire Room if they are standing too close to them when they are reattached.
  
• There is a possibility that the in-game speedrun timer may severely under-count your actual run time. If you are a speedrunner, we recommend that you use your own timer rather than the in-game timer until this is addressed. (Note that the in-game run timer starts counting when the elevator door opens at the beginning of hc_t0a1.)
