Iron Sky
A game by @strongcavec998d on Spawn.
Genre: Tower Defense, Strategy
# Iron Sky You command a city's air defense against waves of incoming aircraft and missiles. Place different types of turrets strategically around the cityscape to intercept enemies before they reach your base, earning money from each kill to upgrade your arsenal. Balance your resources carefully as the attacks grow fiercer with each wave, and don't let too many enemies slip through or you'll lose the city.
