A train arrives at the Groundhog Station. Initially, everybody is just standing idly. You are put into the role of one of the people on the platform or the train and can move and act around. After a minute or so, the train leaves, the scene resets, the train arrives again, and you are put into the role of a different person. The previous person plays back what you did last time (similar concept to Time Rifters). This way you can bring the scene to life by filling each persons role and making them act out different things, like greeting each other with a handshake, or one person waving another goodbye. This requires a Hydra.
