Unfortunately Unity insists on not improving their CharacterController, which is only capable of moving the character in a single plane. Even though most of the games use the basic controller schemes, with new games and their technology the need for different type of controllers emerges. Unity at least should bring new different types of controllers, or have more options for their CharacterController. The project includes a player controller that does that latter by extending a RigidBody object with a variety of parameters. One of these parameters is the rotation in space (up vector). Taking an up vector it updates its front and right vectors accordingly at each frame. It has many more parameters built-in coming with base features such as slope walking, and advanced features such as climbing. It also adds some animations as a flavor from Mixamo.
