Special Units are built at Special factories and Shipyards. Special Units use a different unit cap to ordinary units, as he cap starts at 0 and increases by 1 for each farm that is owned, with a maximum cap of 4. A Transport Ship (itself a Special Unit) can carry two Special Units, but cannot carry flying Special Units or boat Special Units. All armies have a cheap (but weak), balanced (mid-price and mid-strength) and strong (but expensive) Special Unit, Along with a Transport Ship. The Dwarves, Trolls, Islanders, Ninjas, Space Police and Space Criminals have one (balanced) special unit each, unlocked by collecting all minikits in Act 2 of their story.
