ZERO Sievert 2 Early Access Launches With Steam Deck Support

The sequel to the radiation-survival game ZERO Sievert 2 is entering Early Access today, bringing a heavier visual load to PC and handheld platforms. This shift matters because the new art style demands more from your hardware than the original title did. Players who rely on portable rigs need to know if their current setup can handle the increased system requirements before they commit to the purchase.

Sequel introduces demanding visuals and co-op while optimizing for handhelds

Zero Sievert Team is releasing the game on Steam with confirmed support for the Steam Deck from day one. The developers have structured the Early Access phase to allow for continuous optimization specifically targeting handheld performance. This approach gives players a functional experience while the team works toward the full 1.0 release.

The sequel introduces a new, more demanding art style that sets it apart from the first game. This aesthetic change comes with increased system requirements, meaning players might need to adjust settings on lower-end hardware. The core gameplay loop remains, but the visual fidelity has been significantly upgraded to match the new direction.

Beyond the visual overhaul, the game adds online co-op functionality, allowing players to tackle the radiation zones together. The developers stated they plan on having Deck support for early access so they can keep working on and improving it leading up to the 1.0 release. This feedback loop is central to how the game will evolve during its Early Access period.
