Followers of the CW series are more than a little familiar with Spores and Phantoms. These were flying/ethereal enemies that required specialized defenses. In the case of CW1, you build SAM sites. In CW2 you build Phantom Coils. In Game 3, Particle Beams are your salvation. Spores in Game 3 also originate on the map (rather than off the edges). Like in CW2, you can use this to plan your defenses…. and offensive maneuvers. After all, why sit there and shoot down spores all day when you can instead go maraud a Spore Tower instead?
