Valve Software, the master mind behind Steam is now seeking to expand with Steam Cloud, the next major update for the digital distribution service. Steam Cloud will allow gamers to store not only their game profiles and graphics setting, but also all of their savegames created through Steam for life. You won't need to worry about your savegames anymore. All the data will be automatically uploaded to back-end servers whenever you go online. It will be accessible from any PC at no cost and there will be no space limitations to worry about. The first games to offer Steam Cloud support will be Half-Life and Half-Life 2, Counter-Strike, Team Fortress 2 and the forthcoming co-op shooter Left 4 Dead. Steam Cloud will also be freely available as part of the Steamworks set of developer tools. In addition, Valve plans a couple of other updates for the Steam platform in near future. They will include auto-updating of your computer's device drivers, social features including events and calendar systems, 'official' community pages for games, pricing localised to your country's currency, Amazon-style recommendations and shopping cart systems, and more payment options.
