This is 'skin' for Major crisis that changes the look of the cacodemons for something akin to doom64's aesthetics.
With their yellow eye, darkened skin and chained arms, these Cacos are much closer in asthetics to the doom64's than the standard variety...
Based on spritework by the ever-talented eriance/amuscaria, with the death sound from playstation/doom64's caco.
As with the doom3 imps, they do use a completely new set of sprites, sounds and code, meaning they are more than just a straight sprite-swap on this occasion.
At present they lack all of the extra deaths and other anims that the classic caco in Major Crisis do, but perhaps they will be added to over time?
feel free to have a go at adding more!
