Though Ark: Survival Ascended has the same core gameplay loop as Ark: Survival Evolved, there are some differences between the two titles. After all, though it has undergone a series of major updates and expansions since it was launched, Survival Evolved is now nearly a decade old, having been released in 2015. The multiplayer dinosaur survival game has remained wildly popular, and Ark: Survival Ascended updates the game to the much more powerful Unreal Engine 5 while including the expansions for Evolved, including Scorched Earth, Aberration, Extinction, and more.
