Funcom has revealed a bit of backstory on the secretive faction, which is only natural since it's Illuminati week at The Secret World website.
Funcom says that prospective Illuminati players will need to find the group's secret headquarters in New York City, as well as undergo "rigorous psychological tests." The group then molds its raw recruits into "focused and efficient Illuminati machinery," and the end goals are victory in the eternal war for influence, knowledge, and power.
The article also hints at an Illuminati ranking mission that involves a young United States senator not yet under the group's thumb. Read all about that and more at MMORPG.com.
