Chapter Approved 2026-27: Mission Deck
Wars fought in the 41st Millennium are rarely simple pitched battles. Both sides of the conflict have their own agendas, aligned with their roles in the overall war and the forces at their disposal.
This pack contains all the cards you need to set up and play exciting games of Warhammer 40,000. Battles are designed around the way you build your armies – accommodating both narrative play and balanced competitive games. It includes a mission sequence to follow, and the Deployment, Force Disposition, Primary Mission, Secondary Mission, and Twist cards needed for two players. Also included are six cardboard Operation Markers, used to track your progress in a number of the Primary Missions.
This pack includes the following cards and accessories:
– 6 Deployment cards
– 10 Force Disposition cards
– 30 Primary Mission cards
– 18 Attacker Secondary Mission cards
– 18 Defender Secondary Mission cards
– 6 Twist cards
– 6 Operation Markers push-out tokens
– 1 reference booklet
All cards measure 70mm by 121mm.
