Alien Games - take control of or fight against the little green men from outer space!
Aliens have captured our imagination for many years - we have all seen programs about supposed alien crash landings, and watched films such as ET and Star Wars. Many people believe that extra terrestrial life lives and that there are planets far away with intelligent life. Alien games allow you to explore new worlds, fight against hordes of inhuman species, and test the limits of space. Battle for the Galaxy for example allows you to build a military base on a strange world and send mechanical units into battle to conquer new territory. Check out our hand-picked selection of fun and interesting alien games today!
Battle with supernatural forces and advanced alien civilizations in a range of free alien games. Play for free in your web browser.
