slicer24, it is actualy pretty simple to defeat the boss. Gather a lot of huge pixel squads. And leave the rest at your base. The boss should be attacking someone else, send your units into its base. Your units will be stronger in the thing that makes your base better. And boom you destroyed the boss. Then send your base to where the boss used to be, and there you go!
i made another cell pool far away and a glitched happened. i let it collect food and i didnt do anything else with it. and soon it starts to take care of its self! and it attacked me!
The best way to kill a gaint is to use speartons. At the last battle, when the statue turns into a huge giant. Use as many speartons as you can, and take control of one, too.
