About this Mod
This is a mod about the Aliens and Predator franchises; adding xenomorphs, anathema (pathogens), and yautjas to your worlds.
I've noticed that for 1.20.1, there aren't many Alien mods for Forge. Gigeresque is unfortunately a Fabric only mod. You can use it in Forge/Neoforge with Sinytra Connector, but the developers stopped updating it for 1.20.1 and it often doesn't work in large modpacks. The Box of Horrors adds the facehugger, chestburster, xenomorph, and yautja; but only as cameos. So because of that, I've decided to make this mod!
So far, this mod adds xenomorphs, anathema, yautjas, xenomorph chitin armor, royal xenomorph chitin armor, and yautja armor.
Xenomorphs spawn naturally in all of the Overworld's biomes when it's nighttime. Hellish Xenomorphs spawn naturally in all of the Nether's biomes. Anathema spawn exclusively in dungeons. Yautjas spawn in jungles.
Xenomorphs and anathema will fight each other, just like in Aliens: Fireteam Elite. Yautjas will hunt down players and most hostile mobs (including xenos and anathema).
Xenomorphs spawn more frequently in caves, and they get easier to find the deeper you are.
Anything with (W.I.P.) after its name is either not available in survival or it has no use.
Anyways, more updates are coming out sometime soon.

HELP WANTED!
I'm looking for mod developers for a small team. I need volunteer artists (3D modelers, texture artists, and animators) and coders for my mods.
I want to remodel and/or retexture every mob in this AVP mod, but I don't have the skills to do it myself. And this mod won't ever be able to be anything more than a beta build if I continue using MCreator for everything. If you are interested, then either reach out to me on Discord (username: geckokingyt) or just DM me on Curseforge and I'll discuss the details further.
