Watch as a war happens! When the shields of an army is broken (the top number) the other army can go all out to defeat all of their army. When two soldiers of different armies touch, they battle. Usually, they both get defeated, but sometimes, one can defeat the other and continue. When one side's lower number drops below 0, they lose. It does continue, but that's just if you want it to.
New background update! I would recommend turning on 60 FPS mode with scratch add-ons or Turbowarp.
