Vent Mod is an addition to Black Mesa's "We've Got Hostiles!" chapter, adding new areas to the last bits of the chapter. This mod re-adds and revamps the vent sections of the chapter, which were cut from Black Mesa due to their inadequacies. The issues that they had in the original have been (hopefully) done away with.
Version 2.2 of the Black Mesa Vent Mod. The zip file contains all of the relevant materials.
Are you sure the mod is complete?
In the readme is says there should be a 3rd map named "bm_c1a3d" but there isn't.
Ah, the readme is wrong. That there's a holdover from when there was a D map. Trust me when I say though there have been no versions of the mod released to the public that contain a D map.
I hope you will update this for the official Steam release, which is out by now.
Thank You! It's great! But is it compatible with the latest release of Black Mesa?
