Microsoft has signed up more than 350,000 subscribers worldwide for its Xbox Live online video gaming service, as it prepares to bring the platform to Europe. The company had claimed sales of 150,000 subscription kits one week after its November launch and 250,000 kits as of the first week of January for its initial roll-out in the United States and Canada. Microsoft launched the $49 subscription kit enabling online play for its Xbox game console last November in the United States and in mid-January in Japan. It will be released in Europe on March 14. The first set of downloads was recently launched for the game "Mech Assault," and Microsoft registered more than 172,000 downloads for the new content in its first week. The next major game to have downloads will be "Tom Clancy's Splinter Cell" from Ubi Soft Entertainment; a new level for the game, called "Kola Cell," will be available simultaneously with the Xbox Live launch in Europe.
