JusTD

A sci-fi themed tower defense where you will need to manage resources to be able to build turrets and other buildings. You also need to pay attention to enemies that can attack your buildings and towers and need to make sure you always have enough resources to repair them. Your turrets level up as they deal damage to enemies, but they have limited amount of ammunitions, so you need to build mines, refineries and factories to generate different types of ammo for your turrets. Almost standard TD, but not quite. :)
