To make the present a better place to live in, a time traveling organization sends a group of heroes back into the prehistoric age to alter the future. Players have complete control over time. They can stop, rewind and play depending on the situations.

The game offers a unique single-player co-op experience as multiple copies of the same person is made during time travel. There are over 16 characters in each of the 6 time periods, each with their own traits.
