Space Hulk: Death Angel – The Card Game: Mission Pack 1

From BoardGameGeek:

Your mission is not over, and failure is not an option. While you may have survived the harrowing challenges of Death Angel, the mission is far from over. The Mission Pack 1 expansion brings twelve new Location cards to provide alternate missions for players. These cards are seamlessly incorporated into your Death Angel game - simply choose whether you want to use the standard Location cards or the ones found in this Mission Pack and build your mission as normal. But beware! New terrors have emerged in the form of Adrenal Genestealers: deathly agile and relentless. These dangerous new foes will pop out from every dark corner, unleashing attack after attack. Also included in Mission Pack 1 is an all-new Terrain card that will threaten to thrust unfortunate space marines out into the cold embrace of space.
