Revenge of the Titans (PC) PC

First they came from the skies, and we repelled them with hired spaceships on a shoestring budget! Now they're back, and they're sending their ground troops to destroy our bases - thirty-ton monsters with glowing eyes and slavering jaws! And we still don't have any money! Quickly assemble a defensive position using blaster turrets, upgrades, tiny battledroids, barricades, mines and tangleweb, whilst obtaining the necessary funds by mining nearby resources - as the relentless march of the Titans approaches your base. Research new technologies and buildings as you defend your Earth bases throughout the solar system from the Titan onslaught. This is the ultimate mash-up of real-time strategy and tower defence.
