Ark: Survival Evolved is constantly receiving updates from Studio Wildcard. Recently, it was announced that the Procoptodon, a gigantic prehistoric kangaroo-like dinosaur, will be coming to the Xbox One some time later this week.
The reveals keep appearing as the newly announced Megalosaurus will be coming to Ark: Survival Evolved. The Megalosaurus is a fairly docile creature that sleeps during the day, and becomes actively aggressive at night. Nighttime raiders may appreciate what this dinosaur will have to offer.
Details of the release date have not been announced yet, but this nocturnal carnivore should be coming soon.
