Release date

May 14, 2026 for Early Access / Game Preview.

Platforms

Windows PC on Steam plus Xbox Game Preview. Check the relevant store before purchasing because platform support can expand.

Co-op

Play solo or in online co-op with up to four players, according to the official Steam description.

Full release

No fixed date. The developer's Steam Early Access FAQ estimates roughly two to three years, which is a development estimate rather than a promise.

What Early Access means for route planning

Resource density, recipes, hazards, and progression pacing may change between updates.
Build short repeatable routes before relying on exact coordinates or fixed spawn assumptions.
Record the patch version when sharing a route with other players.
For co-op, agree on a regroup point and return trigger before splitting roles.

Where to start on RouteForge

Use the beginner route guide for the first loop, the resource checklist for goal-based gathering, and the co-op planner to divide jobs. The update tracker explains how RouteForge labels confirmed information and route assumptions.
