Mother Cells were temporary additions to Experimental Mode added on 2015-06-11. At first they seemed to be simply a larger version of the virus, but with a few differences. Located in the center of the map, it was the size of a ~5000 mass cell and ejected 10% \ 1/7 of the map's food in random directions around itself. The mother cell could not be pushed or moved through. The large amount of food surrounding the mother cell led to a high concentration of smaller cell activity, which brought larger cells to the mother cell as well. Using the mother cell for food/hunting was a high risk, high reward activity. The Mother cell had a limit of 10.000 score, unlike Spawners, which can grow larger than the map.
