While liveblogging the Ubisoft pre-E3 2010 press conference, Crush! Frag! Destroy!'s Sage Knox noticed a suspiciously large Steam update to a series of classic titles:
"As if Valve’s E3 plans couldn’t get any more confusing and ridiculous.
"Suspiciously, on the eve of E3’s official kick-off, Valve issues a massive update to their aforementioned suite of Half-Life 2, Episodes One and Two, and Portal, which was the subject of a stealth update that eventually led to the announcement of Portal 2. Hit the jump for more intricate details."
