(New box, but the game inside is the same as ever.)
Chrononauts is a fast, exciting, multi-layered time travel card game for 1-6 players. The huge deck of 135 cards features a unique 32 card timeline deck that's used to track Ripples and Paradoxes. Players become Time Travelers, seeking to return to their original alternate realities by changing history (done by preventing assassinations, averting disasters, and so forth).
Or you might choose to go for victory by collecting up the right combination of amazing artifacts. If things just aren't going your way on the timeline or with the artifacts, you can always win by doing your duty as a Time Repair Agent, fixing paradoxes.
