Like skinning monsters:
Initially just for the Sktrooper, as I use the original Oldskool mutator that Usaar33 made that gave access to the Sktrooper model over half of my bots use, as they needed team colors...

...I've since amassed a rather massive collection of skins for various monsters, because I edit maps too and along with changing projectiles and other things, sometimes I change the skins of the monsters on maps so they've got their own look.

Shared some of these over the years, now I'm sharing all of the ones I have (exception of those previously released in skinpacks) because why not?

No need to credit me, so far as these go even the ones that are largely my own work are based on the work of others so nothing in there is originally entirely all me.
