Eternal is an overhaul mod that changes a lot of features from vanilla ARK. It adds 600+ new dinos at its current state, most of them can be tamed in different ways. Some of them can be evolved from creature A to creature B. Eternal has around 30 bosses so far, some rather easy and some almost impossible to kill. It adds more difficulty and diversity. And the best thing about Eternal, is that its WIP, meaning we still have alot of new features we are both thinking about and working on. We will not, however, release content and start with adding any more content until the previous content is working.
