Alpha Rex is a terrifying new boss that will hunt down anything in its path. As it charges through the world, it smashes trees and tears through leaves, leaving destruction behind and creating an intense, challenging boss fight.
This add-on does not disable achievements!
This is the first version. If you notice any errors or have suggestions for improvements, feel free to leave a comment!
