i only know how to do weapons.
The only animations the pistol has is
Shotguns will be a pain because black mesa shotgun pump animation is separate than shooting, tf2 shotgun pumps in the same fire animation.
i might have to trash this in the future if there is copyright issues.
i think there is enough tf2 items on the workshop to cover every single black mesa asset but i would have to ask for permission for all of them.
i have an idea how the gauss gun scene would play out.
these are the voice sounds i would use in that scene.
demoman_activatecharge02 - "charge it doc"
demoman_autodejectedtie04 - "ya bleedin idiots"
demoman_autoonfire03 - "fire"
