About this add-on
The Duplicants scramble to shoot down a massive impactor asteroid before it decimates their homebase!
In The Prehistoric Planet Pack, you'll dig deep into a new starting planet to uncover new biomes, dinosaur critters and primordial plants, natural elements and resources, and anti-asteroid explosives for planetary defense.
Wild New Biomes
Explore brand-new biomes that range from warm and lush to chilly and caustic. Take a foray into 360-degree farming, as several of the planet's native plants have evolved to grow on walls or ceilings.
Wrangle dinos large and small, and keep an eye on the carnivores: their appetites can wreak havoc on a ranch.
Useful New Elements
Discover an abundance of new elements for construction, refinement and power. Duplicants revel in the earthy aroma of peat as it fuels both power generators and the new smoker building that transforms tough dino meat into tender brisket.
Archaic Aesthetics
Customize your colony with exclusive prehistoric-themed cosmetic skins! You'll find a trove of paintings, buildings, outfits, Atmo Suits, and more in the freshly restocked Supply Closet. There's even a new set of fossil sculptures!
Incoming Asteroid!
Head straight for the surface to build a blast line of defense against the imminent threat of an impactor asteroid! The sooner you've blasted it out of the sky, the sooner your Duplicants can get back to peeing in the water reservoirs.
Plus, you never know what you'll find in the asteroid debris...
New biomes to explore, critters to ranch, and disaster to avert - hit it with your best shot in The Prehistoric Planet Pack!
