The January update is the biggest one yet for the Early Access title, and in it Warhammer 40,000: Inquisitor - Martyr is getting its single player campaign. It's only the first chapter and it mostly serves as a tutorial, but will introduce key gameplay mechanics and is a taste of what's to come. Sometimes that's what Early Access updates are all about. Along with this first chapter will be a new terrain setting and a playable class, the Primaris Psyker Inquisitor.
