The term "repack" in the context of video games usually refers to a version of the game that has been modified or repackaged to be more accessible or to bypass certain restrictions. The Nioh Complete Edition v1.21.01 repack likely includes updates, patches, and possibly the DLCs, making it a comprehensive package for those looking to dive into the world of Nioh. The version number suggests that it has been updated to include fixes and possibly new features or content up to that point.
