collision detection: A bioterror attack in World of Warcraft
Dig this: An Ebola-like epidemic is raging in World of Warcraft, the enormously popular online game — and it’s killing players left and right. The trouble began when Blizzard, the company that runs World of Warcraft, introduced a new opponent called Hakkar, the “god of blood”. When you fight him, as a defense he infects you with something called “Corrupted Blood”, which shaves off your hit points so rapidly that your character dies very quickly. Problem is, the Blood is infectious — get close enough to another player and you’ll pass on the disease.
