Half-Life 3 Rumors Reignite After Valve Employee Lets Codename Slip

A Valve employee apparently let a codename slip unintentionally, reigniting rumors of Half-Life 3. Since Half-Life 2: Episode Two, Valve has neither confirmed nor denied a third mainline Half-Life game, and is rumored to have canceled at least one attempt. The fresh evidence comes directly from Valve, though the person revealing it seemingly didn't intend to.
