Being the first action role-playing game set in the universe created by Games Workshop, Warhammer 40,000: Inquisitor - Martyr is a worthy purchase for fans, with a well-crafted campaign deeply invested in the universe's lore. Sadly, the gameplay experience, while functional, is quite derivative, and the few features setting it apart from other action role-playing games are not enough to make it an essential purchase for those who aren't familiar with the Warhammer 40,000 universe or aren't big action role-playing game fans.
