Settings

A leafcutter ant colony must repel an advancing swarm of army ants. Your nest is located to the east of the army ant swarm. Your nest entrance has already been excavated.

The level starts at night.

The forest floor is covered with harvestable saplings.

You must choose either taunt or stun majors before playing the level. You start with 7 extra minors and 7 mediae.

Notable enemies

Other enemies are on the same side and are hostile to the ants.

Blue rove beetles, small whip spiders, and small velvet worms inhabit in your nest.

Surface enemies don't invade your nest. On later days, they fight among themselves to keep their own number in check.

Harvestmen, spiny devil bush crickets and velvet worms roam the forest floor all day.

Jumping spiders and leaf-mimic praying mantises only appear on the surface during the day.

Blue rove beetles and large whip spiders only appear on the surface at night.

A huge whip spider hides under a log in the middle of the map. It only comes out at night. It starts coming out from the fourth night on easy, medium and hard, from the third night on extreme and from the first night on impossible.

Army ant

Army ants only appear during the day. The progress bar appears on the screen along with them to indicate their movement. Army ants move along the vertical lanes and gather any food on the way. Majors take the lead and stand guard at the intersections.

The progress bar extends quickly to the right over time, regardless of the number of army ants on the map. It still moves slowly at night despite not being on the screen.

Army ants move eastward each time the progress bar goes above a threshold and eventually invade your nest at the end. Army ants retreat to the previous lane when the progress bar goes below a threshold.

You must eliminate army ants yourself to make the progress bar retract. You win when it is entirely depleted.

Scouting groups occasionally appear on empty lanes. They only consist of army ant mediae. If they discover your ants, they will run back to the spawners to call for reinforcement. Extra army ants arrive at the noted location without affecting the progress bar.

Challenge

Phorid flies appears every 6 minutes 30 seconds at specific locations on the surface.

Trivia

• In real life, whip spiders usually fight for mating right by circling and probing each other with their pedipalps. This unique animation can be seen only in this level when whip spiders confront each other on the surface.
