This week, action-RPG Warhammer 40,000: Inquisitor - Martyr came out of Early Access on Steam, the latest in a long line of incomprehensibly titled games inspired by the Warhammer miniatures series. It's a decent spin on the kill/loot/explore formula popularised by Diablo, but what it's especially good at is making the complex and daunting lore-filled world of Warhammer 40k feel approachable.
