Jun 28, 2011 - Verbena Games is pleased to announce the release of PlanetSave TD 1.0 for iOS. PlanetSave TD is a tower defense game that pits you against the aliens. Your mission is to go from point A to point B without being destroyed by the aliens. To accomplish your mission each tower has its own unique set of defenses that is upgradeable as you accomplish new levels. Be careful though as the aliens also have their own unique skills including invisibility and increased speed.
