This card pack was released on August 30, 2011, and was the first to be released in the Cahills vs. Vespers series in conjunction with 'The Medusa Plot.'

Website Introduction[]

The 16 cards from this pack unlock a crucial mission — there's an artifact hidden in an ancient city, and you must find it before the Vespers do. The cards give you the gear you need, but it'll take more than gadgets to complete this mission. Only the bravest (and sneakiest) Cahills will have what it takes to save one of history's greatest treasures. Be sure you make it out in time—lives are riding on your success.
