There's a new DLC available for the PC version of Warhammer 40,000: Inquisitor - Martyr, and the title is: Occult Siege!
A secret base of the Inquisition has come under attack by Chaos forces. The strategic importance of this location requires a certified agent to take command and organize defences until relief forces arrive.
This DLC contains a special Priority Assignment. An investigation has its own plot and consists of a series of new missions. Upon completing the Assignment, you will be rewarded with a unique Tarot card. (Please note that this assignment is only available after unlocking the Agartha Subsector.)
Additionally, Patch 1.3.1 is also live, read the full patch log here.
