To Protect the Earth from alien invasion, you're given a ship class AT-021. But unfortunately the Earth doesn't have enough resources to supply new arms to the ship. Improve the ship by collecting weapons through battles and buy turrets to defend.
Defend the castle from the attack of orcs and other creatures. Get gold in order to create soldiers and archers, you will also be able to repair and upgrade units.
Protect the Kingdom of Magicka. Build special walls to direct the arcane enemies of the kingdom as your elemental cores prevent them from reaching the sacred halls.
