Studio Rivi's Overrafted Demo Hits Steam Ahead of December 2026 Release
The demo gives the co-op survival audience a hands-on test of a role-splitting raft game several weeks before its December 2026 Steam launch.

Studio Rivi released a free demo of Overrafted! on Steam on October 16. The cooperative survival game puts up to four players on a raft crossing unknown seas, splitting roles like steering, fishing, gathering materials, and repairs. Wind, currents, volcanic eruptions, and sea creatures threaten a raft that degrades as it travels. Reaching port lets players upgrade the raft and tools with collected materials. The full version is set for PC via Steam in December 2026.
Roles split four ways: someone steers, someone fishes, someone gathers materials, someone patches the raft. The division is the design, not a suggestion, because the sea keeps changing shape each voyage and the raft keeps falling apart.
Ports are the only relief. Materials collected along the way go into upgrades for the raft and tools. A bigger raft opens more activities and more surface that needs managing, so expansion carries its own repair load.
The demo runs about ten minutes or more and supports Japanese. The full version is scheduled for PC via Steam in December 2026.
