Aliens Versus Predator 2 pitted colonial marines against predators against aliens. It was an asymmetrical first-person shooter that stood out when it was released in 2001. For seven years, the multiplayer servers pulsed with life. No dark corner offered sanctuary, cloaked predators disemboweled marines, and marines surrounded themselves with thickets of spider mines, and, all the while, alien players crawled through the vents.
Then in early 2008, Vivendi Games, parent company to the shooter’s publisher Sierra Entertainment, merged with Activision. Within a few months Sierra announced it would be shutting down the servers for 21 of its games. Aliens Versus Predator 2 was one of them. By the end of the year, Sierra itself was shuttered. The master server browser going down was almost an apocalyptic event for the players. Almost.
