Spore And Ruins: Paroxysm

"Origins" version (file):

Imagine this: You are a scientist, experimenting with a strain of a particular bioweapon related to fungus. You are trying to refine it to be only capable of infecting humans. It has quite a many impurities, such as being able to infect cows, whales, calvary, enderman, creepers, even triggering reactions in pigs that usually lightning causes to make them humanoid. Skeletons and blazes get contorted into forms that don't even resemble them. Golems? The fungus takes them too. Most others are stretched into human-like forms and faces mixed with their own physical appearance, resulting in truly horrifying things. Thankfully, it doesn't spawn naturally.

Now, you are in your hazmat suit, ready to test this imperfect sample on the countryside or some small towns with some villager slaves. Then again, you'll probably get the villagers killed as well, so it's not like you're any better.

"Normal" version (file):

Taking place after the infection already started, you are a mere simple man trying to survive the apocalypse. It is still unstable and doesn't discriminate based on species. As time passes, the infection will get progressively worse, with stronger enemies spawning naturally. Unlike SRP, this doesn't matter based on points, simply time, although this will still simulate evolution phases. These phases will occur rapidly within a time period of 30 in-game days.

The phases will follow like this: Evolved, Hypers, Organoids/Evolved/Hypers, Calamities

Also, the crimson forest is quite infested by the infected.

Good luck. <3

P.S., the conversions are also compatible with sculk horde, FAW, or TFTH if you wish to add them.
