Colony 1's circling death squads shifted around the top of the center food store, intercepting 2 and 3's workers at their exit, resulting in a 3-way battle.
Finally, Colony 2 was the 4th colony to fall, which left 1 colony in each quadrant of the map. the 2 high-aggression builds, one of the all-medium builds, and one high energy build.
Colony 1 seemed to keep the pressure on 3 and 7, who stayed between 200 and 300 ants for the next good chunk of time. However, it was stretching itself too thin, as it dropped from a healthy 450-500 ants down to 300 or so and stayed there while it kept sending out death squads to the others.
Colony 4, on the other hand, maintained a healthy 500 ants as it focused most of it's workers toward the food store down the long hallway, only sending a relatively small amount out toward the center food store. Those that did go to the center were generally not attacked, since 7 and 3 were acting as meat-shields for them. Even if they did get attacked, their aggression was medium and they were able to fight back as needed. It seemed that 4 simply needed to hold out for the other 3s mutual destruction, and then pick off whatever remained.
1, 3, and 7 kept battling on. Their numbers dropping to ~250, ~200, and ~100, respectively. Colony 1 and 3 eventually got a semi-decent flow heading to the store down the long hallway, and most colonies moved away from the center food store aside from Colony 4, who was now running low on their own hallway store.
After a long-fought battle, Colony 7 finally fell to 1's death squads, and 3 was shortly behind.
Just as they fell, Colony 4 finally finished off their hallway food store. This caused the majority of the workers to fracture into 3 groups: Most were smart enough to venture into their neighbor's untouched hallway food store. They have maximum energy and could easily make the trip past where the old colony stood, into their hallway, and back. Another smaller group shifted toward the middle, into danger, but to the closer and more valuable food store, while the rest were stragglers that kept going down their own hallway to a food store that was no longer there.
It's important at this point to note that, at this time, Colony 4 was comprised entirely of workers, 500 of them. Colony 1 was comprised almost entirely of soldiers. Of the 260 ants, 222 of them were soldiers with only 38 workers.
