In all rounds, the viltrumites spawn at the edge of IoM territory and are immune to chaos corruption. Any potential viltrumite-human hybrids don't inherit human mutations such as psychic powers or the Pariah gene.

R1: The viltrumites make a beeline towards Terra with the intention of killing the emperor. They can stop to rest and treat their wounded, but nothing else

R2: The viltrumites try to establish themselves as a faction, capturing territory, technology, growing their numbers, and taking slaves. Their goal is the domination of the IoM

R3: The viltrumites sneak onto an imperial world >!like they do to earth at the end of season 4!< with the goal of blending in and growing their numbers. Their goal is the same as round 2.
