The popular bear-and-bird duo are back in Banjo-Kazooie Returns, a fan-made mod to the original Banjo-Kazooie game. The new game reuses elements from the original, but adds brand new worlds and music.
The mod is being developed by the Mario Party Legacy group using the Rareware Central Banjo's Backpack level editor. The editor allows you to import your own models and use existing Banjo-Kazooie objects and collectibles to create your own levels. Michael Koczwara, also known as SuperZambezi, works on the game as a side project, so there is no official release date as of right now.
Banjo-Kazooie Returns is intended to have at least as many levels as the original game, although both the levels and music are being completely redone to create a new gaming experience. You can keep up with the mod's progress on Koczwara's Twitter profile.
