From Vivendi Universal Games:
During the development of Empire Earth, we subjected the game to tens of thousands of hours of rigorous testing. In the days since the gold masters discs were released to manufacturing, we've continued testing in conjunction with our worldwide group of beta testers. This continued effort has allowed us to add further polish to the game.
We're proud to introduce the 220.127.116.11 Empire Earth Update on day one of the product's release in North America. This 1.7 MB file includes many small improvements to what we believe to be an already exceptional gameplay experience. This update is required for multiplayer users only.
