Last year, Funcom delivered a real treat to MMORPG fans in the form of Shadowlands, a terrific expansion pack to the complex sci-fi game Anarchy Online. Now, with Alien Invasion, they have added a host of enhancements, including a unique guild content-on-demand system and organization-controlled cities that add luster to Rubi-Ka’s already ornate environments. The result is a blessing for experienced players of Anarchy Online, particularly those that enjoy grouping with their friends and have excess credits. On the other hand, apart from the new initial tutorial, the expansion offers little in the way of lower-level content to entice newcomers, nor does it offer much for the many players of AO who like to go solo. Still, Alien Invasion does very well what it sets out to do, and the actual alien attacks offer the best moments of gameplay the genre has to offer. The content does not approach that of Shadowlands, however, if only because AI’s scope is much more focused on the high-level team experience.
