Studio Wildcard with Grove Street Games and Instinct Games have released ARK: Survival Ascended, a full Unreal Engine 5 remake of ARK: Survival Evolved and it's playable on Steam Deck.
Currently in Early Access the remake brings with it special Unreal Engine 5 features like Lumen and Nanite, a new advanced physics system with dynamic water, fully interactive foliage and more physics upgrades. They also mention it will include access to all of ARK's worlds like Scorched Earth, Aberration, Extinction, ARK Genesis Part 1, ARK Genesis Part 2, and more but right now only The Island is available with the other to come later. There's also a redesigned UI, cross-platform modding, a new map and tracking system and the list of what's new goes on for a while.
From the 25.12 release notes:
- Fixed multiple server crashes
- Fixed an exploit with the aim magnetism system
- Fixed Official PvE server configs so that the correct rules were applying (decay periods, structure prevention zones, locked structures)
- Enabled BattlEye on Steamdeck
Playable to what point? Well that I can't tell you as I don't have access to the game to test it yet, but I can't imagine it running particularly well.
You can buy it on Steam.
