In the Robots & Psionics expansion set, two new fractions are introduced: the robotic Mechatron Hive and the Nova Cult psionics. With these you can now play three – or four – player games, turning the fun and mayhem up to a new level!

- Mechatron Hive: A collective of robots having recently awoken to become self-aware, seeking their place in the post-apocalyptic world.
- Nova Cult: A secretive cult of human mutants with powerful psionic mutations and unknown ambitions.
