Half-Life 2 will arrive for Xbox 360 and PlayStation 3, according to Valve's representatives.
The ports, which are scheduled to ship simultaneously with Half-Life 2: Episode Two for the PC, will include official Half-Life 2 content available at that point, including Episode Two.
The PS3 and X360 versions of Half-Life 2 are expected to include adjunct titles like Half-Life 2: Episode One and the just-reconfirmed Team Fortress 2. Counter-Strike: Source is also a possibility.
Half-Life 2: Episode One and Episode Two are the first chapters of a planned trio of episodic add-ons to the original Half-Life 2, extending the game's story.
Of particular interest is a single-player game called "Portal," which will come bundled with Episode Two. Portal lets players use a special gun to create gateways similar to those used in Prey. A player could create a portal nearby, for instance, and then make a second portal on the other side of a chasm; walking through the first would transport him safely out the second. Unlike Prey, however, it seems players can dynamically create an unlimited number of portals on just about any surface available. The demo on display showed dozens of ways players could exploit this new technology both in terms of offensive and defensive strategies. Valve has yet to announce which games will use the new technology, but players can get taste of it when Episode Two ships.
In related news, Electronic Arts has clarified that Counter-Strike: Source is not yet confirmed for the PS3 and X360 versions of Half-Life 2.
