This is an ant colony game, the goal is to grow your colony to 100 ants.
You need to keep collecting food while dealing with different threats. You can avoid areas, or focus on an area, threat or food, so there is some strategy needed.
You control the ants by placing pheromone clouds, with different types available.
There are some extra things, like powerups, ants turning into soldiers, nest going into a frenzy when threatened.
