Revenge of the Titans
After a battle has been won the player gets to research new kinds of buildings, turrets and technology. To research new buildings and turrets it's necessary to first research the right technologies. The player can build weapons like different kinds of blasters, rocket launchers, lasers, mines and many more. It's also possible to build barricades, shields and different add-ons that modifies the capabilities of nearby buildings, for example with increased ammunition or fire power. At times the player will get access to power ups that he can pick up by clicking on them. These include cash drops but they can also be special attacks or increased abilities for buildings.
In addition to a campaign mode consisting of 50 missions there are also an endless mode and a survival mode.
