Hello there, long time member of Moddb and part of the Half-Life modding community since the very beginning! Currently working on the brand new Half-Life mod "Dark Matter".
The ventilation shaft from "We've Got Hostiles" is now heavily damaged from air-strikes, and partly flooded thanks to a burst pipe somewhere. I wouldn't recommend going for a swim, the water, and faulty lighting make for a deadly combination...
You know i am just gonna imagine that we will be able down to the bottom of that to the beginning section of "We've Got Hostiles" and there will be H.E.C.U Soldiers guarding the place. But this is just a guess idk maybe the bottom is collapsed and filled with wet rubble that probably wouldn't surprise me at all.
Jumping into the water kills you instantly! Have to stop you going back to the storage facility areas, since that isn't the path Kovac takes ;) Other than that, all the details in the shaft including the broken ladder/fan are all there if you look around after falling to the bottom...
Hmm okay.
Kind of expecting to see HECU and Osprey bits around the rubble, maybe even a few HECU floaters in the water ;)
