Alien Towers are dungeon locations in GRAV. They can be easily spotted on most planets through their tall and slim silhouette which is visible over far distances. Unlike caves, alien towers are vertical dugeons and require a Jet Pack to ascent from one floor to the next within the tower. The homeworld planet has two alien towers accessible which can be found in the desert and jungle areas. Especially for low level players alien towers are a good source of artifacts, as some of the tower floors have central platforms with artifacts placed on them. Although all alien towers are of visually identical outer appearance, some towers hold more floors and platforms with artifacts than others. Those usually tend to be alien towers on mid and high exo planets. The Alien Tower armor set is a reference to the towers and is referencing them in its item description.
