Of course thay failed to target my conveniently packed "Retaliator" nuclear missile launch pads, which by now have stocked a total of 200 units of fiery vengeance.
Meanwhile one of them still has a messed up economy with countless stalled build queues, so they started building a Krogoth gantry. Yup, makes sense.
Aaah, the sweet sound of chain-launched nuclear missiles...
Aaaaand every enemy unit has been wiped, including isolated metal extractors, without having to risk any ground unit. Troops safety lies in FIERY DEATH FROM THE SKY!
