In Chrononauts you play an elite operative sent into the past by a mysterious organization using prototype time-travel technology. You're well trained, well equipped, and in contact with other temporal operatives throughout time and space.

Only...

None of you remember why. None of you remember who sent you back, or what it is you're supposed to be doing. You don't remember how you were even recruited, or when it was that you were trained. Your memory - all of the operatives memories - are swiss cheese. Delicious. Full of holes.

In Chrononauts players explore a cinematic timeline built from popular fiction - movies, TV Shows, comic books, literature, and games. It's part mystery, part sandbox, as players explore the eras in which they find themselves while trying to unravel the secret purpose behind their mission, and their own identities.

Chrononauts is a GURPS 4e game in which players define their characters as their memories return. No experience with the system or access to the books is necessary.
