Using Black Mesa assets as well as much of our own custom made content, 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.

This concept art has been applied on the silo its current design, but with some heavy changes.
EDIT:Heavily outdated
I really like the idea of Sector A being parts of the old complex reused as training courses, it makes the original map more logical and brings more history to Black Mesa.
Yeah! Totally agree with you!
The concept looks good, and I also like your intention to add props to hint at past use of the silo.
