This is a big one... I reccommend you try using explosives, mainly the Ray-Gun on zombies.
I think you'll be surprised of the outcome...

Used Explosives on addon... :)

Fixed more things with the base...
Also accidentally updated the addon with nothing... Lol

Fixed a silly file path issue... T'was missing barricade tear sounds.

Finally and I mean finally... Added the rest of the heads for the Classified/Alpha Omega Zombies.

Modified some base gmod effects to avoid complications with other things...
Some people can experience weird stretched looking particles.

Added more animations and made adjustments for others.

Zombies can move underwater now! They now have movement anims to show for this. Low grav support will hopefully come later.
Added a bunch of Contextual Animations for the Zombies.
These include Deaths for Blackholes, Frozen, Acid, Slipping, Ect.

Added some more hud related thing-a-ma-bobs.
Tweaked the main anim base so it can be more compatible with nZr(I.e they can work with a unmodified nZ Zombie Base)
