The Switch version, which is developed by Studio Wildcard partner studio Abstraction Games (who handled the PlayStation 4 version), will include the complete contents and features of the original game.
Here is an overview of the Switch version, via Studio Wildcard:
ARK: Survival Evolved on Switch includes the complete contents and features of the original game; from the massive and mysterious ARK island to the more than 100 prehistoric- and fantasy-inspired creatures such as the T-Rex, Giganotosaurus, Rock Drake and Reaper. Hundreds of hours of exploring, crafting, survival and combat await players as they go it alone, or group up with thousands of other Survivors to explore the island and solve the mysteries of the ARK.
The Nintendo Switch version of ARK: Survival Evolved will be developed by our partner studio Abstraction Games (handlers of the PS4 port), and we can’t wait for it! The handheld mode provides a fantastic new capability for survivors who want to immerse themselves in the vast worlds of ARK fully! With this new version, Switch players can go directly from hunting and tame while sitting on the couch, to forming online tribes and searching out new conquests when on the bus, waiting in line, or wherever they happen to be.
