About this project
What does Alienated add?
Alienated is a mod that adds the planet Polaio (Po-lay-o) as a seperate dimension. Polaio is full of aliens, which you can see below.
Mobs:
Opoti
The Opoti is a massive carnivore that you can stand on. In the future, I will add the ability to ride it. Opoti can only spawn in the Shootflower Plains.
Tureli
The Tureli is a forest animal that shuffles through the grass. It only eats shootflowers.
How to get to Polaio?
To get to Polaio, you need to craft a rocket using iron blocks, glass, gray concrete, and glowstone.
