The houndeyes sleeping in the room containing the power switch are invisible until I wake them up. It was quite funny finding this out the first time

I'm having an issue halfway through the chapter where the AI disables itself. Its probably a conflict with another mod, I'll update if I find out new info.

I got suggestion maybe you could add the gaping whole in the floor to throw grenade in to take care of all the headcrabs that jumps at you in the dark corridor. Witch was another miner game-play detail in the original. Making the headcrab AI to be timed to all gather in view of the hole with flares to light the area up.

The wall bump-maps are flat in this chapter except for two specific areas.

@Sixteen60
No, it was too good to have been thought up back then, and since we work heavily with lighting and shadows, even if it hadn't been part of the map after all the updates, it'd doubtlessly been added.

@dmn I do agree with you, but I'm just saying, that power outage moment was not in 2016.

@sixteen60 because that event fits very well into the chapter, even the name, and doesn't provide a less ideal experience overall. It's not a bad design decision like the one-way-route is.

Why does the power go out even though that change was from 1.5?

@The American Poet is Dead
The stand-alones only contain the specified chapter, so if you only want to play power up, this is the one you want. Note that the full download includes every map in the game, even ones that don't yet have stand-alones, but still have numerous tweaks, balance changes, optimizations, and so on.

do I have to download the "bmce full game" addon with this or can I just download this if I only want the classic power up

The full download's been updated.

Trust me i'll stay tuned this is great to see it gives me an excuse to replay black mesa again

Not yet, but I'll be updating the full download soon. Stay tuned.

are all of these included in the classic full game
