Your final adventure has taken you where you should never have gone — to the underworld! You must escape and find a barque that can float you safely back. But Cerberus, the infernal watchdog, is on your heels with the intent to guard you forever. In the semi-cooperative game Cerberus, you must help each other traverse the game board without being caught by Cerberus so that you can board the barque. Each card in your hand offers you the choice between a small effect for you or a powerful effect for the group! However, there aren't enough seats on the barque for everyone, so sooner or later, some must be sacrificed. Will you help your group reach the exit, or will you play powerful bonus cards to lay traps for your opponents? Those caught by Cerberus get to seek revenge and victory by preventing all the adventurers from escaping... Each game is different thanks to ten different board layouts and your ability to adjust Cerberus' strength as you please.
