Its my first mod ever for any game so I am pretty proud of myself even though its small and really does nothing that a cheat wouldnt take care. Mind you this allows you to discover and earn the experience from finding the places. You just cant fast travel.

Why can't i see the mod of dead island my acc got any problem
