In Undo: Peak of No Return, players perform nine time jumps to change the events of a Himalayan expedition disaster in May 1972. The goal is to save as many of the members of the expedition as possible. To accomplish this objective, players need to discuss what they know and try to use clues, found in the time jumps, to change fate. Every jump is an independent moment in the past that contributes to the entire event which leads to the demise or rescue of the climbers.

The game box comes with 25 large cards and 70 small cards. It is for two to six players, ages 10 and up, plays in 45 to 90 minutes, and will retail for $14.99.

Pegasus Spiele also released Undo: 600 Seconds, an escape scenario game, into U.S. retail in August (see " Pegasus Spiele Will Release a New 'Undo' Game Into U.S. Trade").
