Half-Life 2 will be playable on the Xbox at E3. Valve confirmed that the first-person shooter will be showing up on the Xbox original, nixing rumors that the game might have been an Xbox 360 launch title. Valve also announced that an expansion pack for the PC version of the game will be available for free to owners of systems good enough to run the single high-end level. No word, alas, on when The Lost Coast will be released. Finally, Half-Life 2: Aftermath was announced as a traditional expansion for the game.
