Ark: Survival Ascended is gearing up for a packed September. Studio Wildcard has confirmed that the survival game will make the jump to Unreal Engine 5.8 on Wednesday, September 30, a notable shift from the team’s previously stated plans to adopt UE 5.7. The engine upgrade lands on the same day as two new DLC creatures: the Gargantar dragon for Dragontopia owners and the three-headed Cerberax for Fantastic Tames Season 1 holders.
The announcement, made via the official Steam news channel, also pins down the long-awaited Therizinosaurus TLC (Total Conversion) overhaul for the end of September. The Theri rework was voted for by the player base, marking a community-driven update to one of the game’s most recognizable creatures. Before all that, a final piece of content for the Astraeos DLC arrives this week.
Unreal Engine 5.8 and the September 30 Update
The centerpiece of the September schedule is the engine migration. Ark: Survival Ascended will move from its current Unreal Engine version to UE 5.8 on September 30, according to the official Steam announcement. This represents a change from earlier communications that pointed toward UE 5.7 as the next engine target. The upgrade is expected to bring performance and visual improvements, though the announcement did not detail specific technical features tied to the new engine version.
September 30 is also the release date for two new creatures tied to paid DLC. The Gargantar is described as the latest dragon to join the Dragontopia roster, expanding the dragon-focused DLC with another large-scale creature. On the same day, Fantastic Tames Season 1 owners will gain access to Cerberax, a three-headed pup that serves as the second creature in that season’s lineup. Cerberax follows the Burrowbuck, which launched back in May.
Therizinosaurus TLC and the Astraeos Finale
Alongside the engine update, the Therizinosaurus TLC patch is scheduled for the end of September. The overhaul targets the iconic Therizinosaurus, a creature known for its massive claws and utility in gathering. The TLC was voted for by players, making it a community-selected priority for the development team. Specific changes to the creature’s abilities, animations, or stats were not detailed in the announcement.
For players looking for something sooner, the final Astraeos update drops this coming Wednesday, August 26. That update introduces the Boaratos to the Greek mythology-themed island DLC, serving as the last content addition for Astraeos. The Boaratos joins the DLC’s roster of mythological creatures, though the announcement did not specify its role or abilities.
What This Means for Ark Players
The September 30 date consolidates several major updates into a single day, giving players a clear target for the next wave of Ark: Survival Ascended content. The shift to UE 5.8 is a significant technical milestone for the game, which has been running on Unreal Engine 5 since its launch. The engine upgrade could have implications for performance, modding support, and visual fidelity, though the official announcement stops short of making specific promises.
The Therizinosaurus TLC arriving at the end of September means players will have a window of roughly a month between the Astraeos finale and the next major content drop. With the Gargantar and Cerberax tied to their respective DLCs, the update gives both Dragontopia and Fantastic Tames Season 1 owners a reason to return. The exact timing of the Theri TLC within the end-of-September window was not specified, leaving open the possibility that it could arrive alongside the engine update or shortly after.
