Megafauna

New in v1.5:

Now includes options to prevent any specific animal from spawning, change the commonality multiplier of the spawns of Megafauna animals (make 'em rarer or much more common), and even the option to disable vanilla animals spawns altogether, if you're looking for a unique challenge (all thanks to Sarg!).

FAQ:

Q: Is it safe to add this mod to existing save files? A: Yes, it is. Just remember to then update your butcher tables' bills to allow butchering of Megafauna creatures.

Version: 1.5

Description:

Thanks to the wonders of today's technology, the small group of scientists that was previously known for bringing the Megatherium-- Uh, I mean, the Megasloth back to life, was able to make the Megafauna Project a reality! This time around, they were able to recreate 38 different species of animals that used to inhabit planet Earth thousands to millions years ago. ...Was that a wise move? Who cares! Now we can all feast our eyes on those glorious beasts as they will slowly inevitably turn all the ecosystems we know upside-down!

Features:

38 new species of animals, all able to spawn naturally in different biomes:

• Arthropleura,
• Doedicurus,
• Daeodon,
• Gigantopithecus,
• Paraceratherium,
• Titanis,
• Titanoboa,
• Woolly Mammoth,
• Elasmotherium,
• Smilodon,
• Chalicotherium,
• Megaloceros,
• Procoptodon,
• Megalania,
• Gomphotaria,
• Diprotodon,
• Short-faced Bear,
• Dinocrocuta,
• Sivatherium,
• Andrewsarchus,
• Dinornis,
• Macrauchenia,
• Quinkana,
• Deinotherium,
• Aurochs,
• Megalochelys,
• Palaeeudyptes,
• Josephoartigasia,
• Gigantophis,
• Meganeura,
• Zygolophodon,
• Platybelodon,
• Purussaurus,
• Uintatherium,
• Pulmonoscorpius,
• Dinopithecus,
• Castoroides,
• Enhydriodon.

These animals are quite rare, and should be a good challenge to either tame or slay. A lot of them can also be used as pack animals for a caravan (with paraceratherium being your new best caravan buddy!). Wooly mammoth, elasmotherium, and josephoartigasia are shearable, and arthropleura, titanis, titanoboa, megalania, dinornis, quinkana, megalochelys, palaeeudyptes, gigantophis, meganeura, and purussaurus do lay eggs. Sivatherium, macrauchenia, aurochs cows, and uintatherium are milkable - sivatherium's milk is very nutritious and quite valuable!

Megafauna will automatically detect and patch both A Dog Said... by SpoonShortage (so you can cure old wounds of your animals and install bionic parts on them) and Giddy-up! by Roolo (which means that you can ride your animals!), so make sure to make it load after those mods.
