All original Dungeon Keeper code has been rewritten, establishing KeeperFX as a true open-source standalone game. Ownership of the original game is still and will always be required for copyright reasons.
When installing KeeperFX 1.0, perform a fresh installation without overwriting any previous versions. Saved games cannot be migrated. There is a [wiki](https://github.com/dkfans/keeperfx/wiki) that holds answers to most of the questions you may have, and we have a large and friendly [discord community](https://discord.gg/hE4p7vy2Hb) where we welcome all friendly new members.
For the full change list see [here](https://github.com/dkfans/keeperfx/compare/Release050...Release1.0.0).
