Glitchhikers is a free game where the player is driving at night and picks up hitchhikers. More an experience than a game as there are no real set goals.
Pro Weird interactions
Throughout the game you will be picking up strange characters who are hitchhikers, through conversations with these hitchhikers you will be partaking in even stranger conversations that you are giving the power to choose your responses to. This makes for a very unique experience that is not often seen in a game.
