Is Ark: Survival Evolved a couch coop game?
Solution 1:
Of course, me and my siblings play it all the time on split screen. First you will click host game, change any settings that you want, pick the place, then hit Create Ark. When you do that it will take a few moments to load up the game, then the first player will make his/her character once that happens then the second player can join and make there character.
Note: When the first person is making their character it will have the exact location you want to go on the right side.
Solution 2:
There is a local co-op option for two players. Source
