While blasting through the forces of chaos in Warhammer 40,000 Space Marine 2, players will quickly notice that most of the imposing Chaos Rubric Marines spew colorful dust rather than blood. This strange phenomenon is even referenced by Titus and his Ultramarines, noting their displeasure at beating enemies without a physical form. After slaying a Rubric Marine, they simply fall apart into a pile of armor as the rainbow particles within fly away, leaving many players confused about what they’re truly fighting in Space Marine 2.
