Valve, the US-based games developer, has announced that Portal 2, the long-awaited sequel to the blockbuster game Portal, will coming to the PlayStation 3.
The company also announced that its online gaming and content delivery platform Steamworks would also be made available for the PS3.
Speaking during Sony's press conference at the Electronic Entertainment Expo (E3), Valve president Gabe Newell said that the Sony gaming platform is by far the most open console in the market.
Newell went on to express his excitement at bringing Steamworks to the PS3..
Calling the PS3 the "best console ever", Newell admitted he had been one of the greatest critics of the device when it first launched.
Explaining his conversion, Newell said: “Sony Computer Entertainment has proved that the PlayStation 3 is the most open platform of all the current generation consoles and has worked extremely hard to make the platform the most desirable for consumers and developers.”
The inclusion of Steam into the PS3 platform will mean that gamers can access automatic updates, downloadable gaming content and community features from the platform.
