Publisher Blurb: This mission throws the Space Marines right into an elaborate deception authorized by a radical Inquisitor. The whole mission seems like an ordinary incident involving Tyranids, but it becomes anything but ordinary when an overly ambitious Watch Captain from the Ultramarines becomes involved. In truth, the Watch Captain is carefully chosen by the radical Inquisitor, and the mission is a huge distraction to cover the Inquisitor’s true actions. Deception features a daring mission in which the Kill-team performs a raid on a heretical Magos Biologis. The Judges liked how open the adventure was to letting the players choose their own path, and the deceptive twist at the end.
