As expected, the Ensemble Studios site now offers more information on the upcoming 10,000 player beta test of Age of Mythology, their upcoming 3D RTS game. People will be able to sign up between June 21 and June 30, at Microsoft.com or at the Ensemble Studios website. Here's what's being tested

This alpha version of Age of Mythology will contain two of the nine civilizations that will be available when the game is released this October. Up to four players will be able to compete head-to-head as a follower of either Zeus or Poseidon on one of two multiplayer maps. This limited alpha version of the game will be available to qualified testers in early July.
