Half-Life 2 Goes Episodic on GameSpot reveals that Valve has changed the roadmap for Aftermath, saying the Half-Life 2 expansion is now to be released in an episodic form. Apparently the first release will now be called Half-Life 2: Episode One. Update: Several comments point out it looks like I have misinterpreted what is simply a renaming of Aftermath to Episode One, rather than a breaking up of Aftermath into episodes. Apologies for any confusion this has caused.
