Toggle two different player control modes in same game.

Hello, people.
How can I toggle between two different player controls inside the same game? For example, in fatal frame, where you walk with basic third person controls, but when equip the câmera the controls change to something like fps game.

You put your Player Controllers into 2 different Pawns/Characters and then let your PlayerController possess the one you want to use.
If you want to switch, you destroy the old one and spawn the new one and possess that one then.
