📋 About This Mod
*Fallout Flood is a new mod event where community members vote on a theme and take one month to create mods based on the winning theme. See more mods from the Aliens and Cryptids jam below. If you are interested in participating in future jams, contact jkruse05.
Rumors persist about a bright light in the sky, followed by a large flash from the south. While nobody knows for sure what that was, all anyone knows is that THEY arrived shortly following. Creeping in the shadows of the swamp and lurking in deep holes, the terrifying black shadows of fang, claw and caustic acid, Zetamorphs. many settlers and raiders have disappeared in the area, their half consumed remains heaped in viscous ooze bound egg clutches.
Oh also the Zetan piloting the UFO had a fancy weapon. yay
-A crashed Transport UFO southwest of Murkwater Construction Site
-A new creature, Zetamorphs, high level foes that are fast and deadly
-A new material used for a few foods, a chem, and a throwable acid syringe.
-A Zetan Beam Rifle that has infinite ammo but needs repeatedly hit the same target to deal proper damage.
The Zetamorphs are tough, flighty foes capable of spitting armor reducing acid, said acid will cause slain foes to burst with a Zetamorph Larva that will scurry about and attack too. Fun! also you can craft throwable syringes that apply the same effect! Fun-er!

and for accepting me and my silly project: jkruse05
Compatibility
The Zetamorphs should theoretically be part of the Mirelurk King and Molerat Boss LLs, so there's a chance that after a certain level Mole Rat Broodmothers might be entirely replaced.

Still Coming
Life and technology got in the way for some of our authors, but you may still see their creations in the future.
yay! I participated in something! although I feel entirely unqualified to stand amongst legends.
It also doesn't help that it took me a while to actually decide upon this project, and even longer to properly
work on it. nothing like staying up extra late to finish it last minute after being given a month to make it, but ah well
I kinda managed in the end.
