AOS
Short for "Age of Shadows" - the version of the popular online MMORPG Ultima Online that moved focus more onto what items the player has in his inventory than his actual skill.
Ultima Online: AoS completely took away any skill involved whatsoever in PvP combat.

aos
A pr0 CS clan which have been to the CPL more times than I can count. Game quality is kept high due to rigorous practice sessions, which sees the clan split into two, to practice the most common match numbers, 4 v 4. This also ensures that they never get to fight alongside each other, keeping the talent fresh.
