Looks like it's just a reskin, like every mod that adds a new alien (Except of course the Muton Centurion mod, which has it's own model)

It's a reskin but also changes around the stats of the viper with extra abilities to keep them a threat late-game.

Hi, it is indeed a reskin.

It's pretty cool, but if the reflectiveness and normalmap made it look like armor plates I'd be ecstatic.

This was a decent design along those lines:

Course, a lot of this could be our tastes diverging which is fine.

Any Chance to add more reskins to this? Like make them look more like an amazon tree python, or like a golden Eyelash Viper? I noticed another mod does similar reskins, but does not apply to "late game" vipers like your mod. So I was curisous, if it was possible that you might consider adding more reskins. So when a mission is loaded up, We have differen reskins of the end game vipers.

Had to change the spit since it's was way too powerful to my type of game.
Wish the bug with the vipers bound shooting through walls and do a lot of things like bound in different locations with the subject bound in one place and the viper in an another location. I think it has to do with the cover or the part that the viper uses cover while using the bound.
if only the viper could turn civilians to either thinman or into vipers, the way the faceless does. Easier would be to use the cocoons and let them spawn vipers.
It's a reskin since it only improves than changes the vipers abilities and AI or charm.
The vipers eyes can stun, the tongue is poisonous and snares its preys with the binding tail.
