Gamershell.com reports that after almost half a year of closed beta testing the Steam Beta is entering its final phase, and is now open to the public (again). To enter this beta, simply download and run the 500K installer. Steam, a broadband platform for the delivery and management of digital content, currently features a variety of Valve games including Counter-Strike 1.6, which introduces the new riot shield, the official CS bot and more. Valve is also planning to deliver Half-Life 2 over the Steam technology this year.
