#1 Revenge of the Titans
Revenge of the Titans is a mix of Real-time Strategy (RTS), and Tower Defense elements developed and published by Puppy Games for multiple platforms. The game brings Single-player mode only and lets the player experiences the traditional Tower Defense game, but with the caveat that foes attempt or ignore to avoid the towers the player place, increasing the difficulty. The ultimate task for each level is to prevent the base from being demolished by aliens by defending it with towers and other defences. During the gameplay, the player has access to research trees that he can use to develop various types of towers against foes. The game acts as the sequel to Titan Attack. According to the plot, the alien race from the moon is trying to destroy the planet Earth via spacecraft, and the aliens return to take revenge while launching the ground invasion. The player acts as the unseen command of the force that must fend off the invasion and deal with an alien attack to restore the peace.
