The Agitator has modest stats, and is not very useful in combat on its own. Its Irritate ability, however, has some very unique properties that give this unit some interesting strategies.
Agitators may not be a great combat unit, however players should not underestimate the power in being able to manipulate the immune system and local predators. Players can also us them as scouts tagging enemy units and following them back to their allies. They could also be used as a kamikaze unit charging into a group of enemy units and then summoning the immune system.
