Ark: Survival Ascended is a remaster of 2015’s Ark: Survival Evolved, but the newer version does not contain all the content released over the lifetime of the original. Enjoying regular support since its release, Survival Evolved received both paid and free expansions after its release. Though Survival Ascended includes a number of quality-of-life improvements in addition to its superior visuals, it is notably light on content compared to the original. This will, however, be rectified over the next two years, according to a roadmap laid out for the game’s DLC.
