WARHAMMER 40,000: INQUISITOR – PROPHECY, a stand-alone expansion pack for Warhammer 40,000: Inquisitor – Martyr. It is a brand new action-RPG experience in the Warhammer 40,000 universe, and although Inquisitor – Martyr is not required to play however, as the story is designed to fit both for new and for returning players. During this stream, I delved into the game, explored its secrets, and slaughtered heretics in the name of the GOD EMPEROR himself!
