Mindreapers are Swarm components which gather intelligence for the Swarm by extracting neural tissue from the target's brain with a bioweapon spike and taking knowledge from it. In battle they fight with psychic feedback and bolste allies. More adaptable than most other Swarm components, the presence of mindreapers causes Swarm packs to fight with more complex tactics than normally.
