ARK: Survival Ascended will not move to Unreal Engine 5.8 on October 28. Studio Wildcard has shifted the upgrade to November 5 while it fixes the remaining technical issues found in the test build.

The Steam PTR remains part of that work, with player feedback helping the team isolate engine problems. Studio Wildcard previously planned an October 28 rollout across all platforms. We covered the test client and original schedule in an earlier story.

The Giganotosaurus TLC and the new Enigmasaur are now due alongside the engine upgrade on November 5. The refreshed Giganotosaurus gets a different combat approach and taming process.

Fear Ascended has not moved. The Halloween event runs from October 28 through November 11, leaving its first week on the current engine build.

Both dates are tracked on our ARK: Survival Ascended page.
