I was thinking that instead of being put through the hazard course to be trained you could wake up somewhere, possibly in a dormitory, then you fall through old broken/crumbly floor into (near) the start of the hazard course. Where Black Mesa has gone through the resonance cascade but a long time ago so there has been no maintenance. We then could have the course to be much more challenging as there are no safety regulations since no one is meant to be being tested at that time - so there hasn’t been maintenance. Meaning there could be (worse) burst steam pipes, dark lighting, broken bridges etc. … even zombies in dark areas. Although the doors and holograph seem automatic there might not be electricity to power them because again, no maintenance (and I guess no power altogether) , anyhow we could possibly turn this into a puzzle by making the player go through a maintenance door to turn on power… or something… There are many ideas that could come from this but I cant think of any more.
I re-read what I wrote and It seems a little far fetched but I want your opinions.
Now that my essay is finished I can sleep (I bet you can find slurred speech in there)
Goodnight.
