Star Trek Chrono-Trek

In ChronoTrek, a time-travel game similar to Chrononauts but set in the Star Trek universe, each player becomes a Star Trek character with a unique identity and a secret mission. During the game, players travel backwards and forwards through history, doing all those things people have always dreamed of using time travel to do: Visiting the great moments of the past, peeking into the future, collecting up artifacts, coming to grips with the paradoxes of time travel, and of course, changing pivotal events and altering the course of history itself.

Explore the history (and alternate history!) of the entire Star Trek universe in this version of Chrononauts. Try to alter history to restore your specific timeline! Maybe you need to ensure that the Federation gets founded, or just retrieve the Orb of Time and some tea. Earl Grey. Hot.
