Where To Get This Card: Day of Doom

The card comes with Day of Doom. This card, along with Cards 297 to 301, forms a Vesper map.


"Cahill intelligence intercepted this Vesper map--the key to their doomsday plans. It contains stronghold blueprints, top secret notes, and coded messages meant for Vesper One's eyes only. But be warned: once you stare into the mind of the enemy, there's no going back. Unless the Cahills defeat the Vespers once and for all, they'll destroy any agent who knows too much."
