Welcome to the wasteland!

Here, the world of minecraftia is stranger than you've ever seen, a twisted spit of land on which monstrosities wander. But the faceless escapees or their blue chasers aren't your biggest worry. Nor are the wandering ghouls and mutants, or the violent wildlife as desperate to survive as you are. Not even are the murderous cyborgs who long ago cast off their humanity in favor of more pragmatic functions. Here, your biggest enemy is yourself, and the time you are given. Every day presents a new challenge, be it Plague, Acidic Rain, or Snow, a hateful sun who desires to dine on your virgin flesh, or the constant daily struggle of finding enough food to sustain your varied diet, only to find your food rotting in your pantry. Here, survival is tough, so you must be tougher, one misstep, one error in judgement, and you could break a leg, or an arm, and that could be the end. climb the hierarchy of technology from simple stone tools to intercontinental travel made trivial. Expand your base with unique defenses ranging anywhere from simple traps to complicated defense systems utilizing turrets, motion-activated lights, retinal scanners, and armed mechanical guards. The world here is confusing, and chaotic, but as the 4 horsemen fly down from the heavens and bless the land with their righteous fury the survivors of that cataclysm shall reign supreme as the lords over even death itself.

What to expect:
For now this project is a work in progress, and development goes as fast as i can play through the mod. there are many bugs which have not been ironed out, and the modpack is not feature complete(much like my other projects lol) However, what is here promises to take up a lot of your time, for better and for worse, and while there is no in-game guide(yet) one is actively in progress at the moment. most of the bare-bones features are in place, and the majority of the early-game is fleshed out. there is plenty to do, but like vanilla minecraft, aside from having fun with friends online, the main focus is to build a life for yourself.
