Black Mesa Sound Replacements
This is a selection of Black Mesa sounds to replace the most common sounds in Gmod, what makes this different than the rest of the usual replacements is that this covers more than just footsteps or other such addons, and also derives it sounds from the retail game and not the 2012 mod.
This covers:
-All player sounds, such as footsteps (including obscure source footsteps), heartbeat/breathing, geiger, all pain sounds etc.
-HEV Fvox Sounds.
-UI sounds like menu clicks and the "talk" sound, flashlight sound.
-Ammo pickup, Battery pickups, Medkit pickups, Ammocrate open and close, and Med/suit Charger.
-Grenade physics sounds, shell "tings", all weapon sounds.
