60 seconds after each time the enemy royal guards are spawned, seeds are dropped in the enemy formicarium. The enemy colony can also get caught in his attack. The male scientist interferes directly in this mission. Other enemies are on the same side and are hostile to the ants. If you have no soldier and stay holed up underground, the counterpart colony immediately invades your nest. If you keep any ants in the enemy nest, the enemy colony gather its soldiers at the underground nest entrance until the invaders have all been removed. It retreats when it has taken enough casualties or when the scientist is forcing you out of the nest. It always follows your most recently placed pheromone marker. It only advances when you move any ants out of the safe zone. The counterpart colony assembles its soldiers near the nest entrance and waits. Workers have Aggressive brood and Defensive. The queen has Second wind and Royal guard on all difficulty, except for easy.

The counterpart colony has 22 gene-thief ant workers, 74 slave-maker ant soldiers, 57 trap-jaw ant soldiers, 66 army ant mediae and 40 army ant majors. Safe zone is the area between your surface nest entrance and the halfway point. The formicariums are connected by a glass tube. You can only have up to 150 brood tiles before attempting the challenge. In this mission, your gene-thief ant colony must defeat the counterpart colony.
