This thesis focuses on which kinds of aspects that would be extra important when two or more persons are collaboratively navigating a single character in a game world. With help of interaction design methods during this process, such as literature researches and usability tests, a low-fidelity and a mid-fidelity prototype were created to find these aspects. In the tests, I also used a high-fidelity game to compare my prototypes with. The conclusion and discussion in this thesis presents different sorts of new ideas and possibilities concerning the different aspects that could lead to developing new interesting games with collaborative navigation.
