Before you

New worlds come with a few questions. Here’s what to know about the Early Alpha.
Report a bugWhat is FuseWorlds?
FuseWorlds is an experimental Windows platform for creating and playing compatible crossover experiences between games.
Does FuseWorlds include the games?
No. You provide the required compatible games yourself. FuseWorlds does not include the original games.
Is FuseWorlds free?
During the Early Alpha, FuseWorlds is free. You still need to own the required compatible games.
Which games work?
Only specific Fusion combinations and versions. Visit the Fusion catalogue for current information and confirm support with the launcher’s compatibility check before setup. Exact tested version lists are awaiting confirmation.
Can I restore my original game?
FuseWorlds includes Repair and Restore Original for supported recipes. What can be repaired or restored depends on the Fusion and its setup. FuseWorlds-managed changes can be removed while preserving unrelated files wherever designed. Read more about safety and restoration.
Is this official?
No. FuseWorlds is an independent fan-made project. It is not affiliated with or endorsed by the publishers or developers of the games it interacts with.
Is FuseWorlds finished?
No. FuseWorlds is currently an Experimental Early Alpha. Features and compatibility are still being tested.
Does it work on every PC?
No. Compatibility testing is ongoing. Supported game versions and hardware vary by Fusion; a successful setup on one PC does not guarantee it on another.
