The new ones had growth pills too. They are taller

finally i can play and see the uncircumcised vorts!

if you touch one of these guys will it feel like touching a ballsack

Nope, only things that modify the map or vortigaunt models will conflict. Any other model replacements are fine.

I have an Alyx replacer it modifies her alyx_intro.mdl (correct me if I am wrong) will it conflict?

@Paynamia ouuu im glad u liked the mod i made! i mostly got inspired by twotime's mod n noticed his mod lacked the other 2004 textures n decided to make a more complete version, i even got some assistance from the guy with baking the textures

@ChalkyMalky
Thanks! Though, this wasn't that bad. It's actually more along the lines of what I originally intended, but I didn't do it like this because I was worried about compatibility issues. In hindsight, people installing the old-style wrong (like that one person in the comments of your addon (which I love btw)) is way more of an issue than something being incompatible.

2004 Half-Life 2 will be real (sans the poopie lighting)

glad to finally see this mod on the workshop! one of my favs when i got started with installing mods for the game. i really hope eventually valve adds a way to make compatibility with mods easier to set up since they literally made it so you can set which version of hl2 to use in a custom campaign/map and i dont see why they cant do that for other types of mods
