This morning, Microsoft received reports that its massively multiplayer space-combat game, Allegiance, was available on store shelves. The game is said to combine the action of World War II dogfights in a typical sci-fi space setting. Allegiance retails for around US$40.00 with an optional monthly subscription rate of $9.95. Gamers can play the game by visiting the Microsoft Gaming Zone or by setting up a server of their own.
