It’s been four years since Episode 2, our last injection of the demon narcotic that is the Half-Life 2 universe, and we’ve been in heavy withdrawal ever since. There may be a time in the future, though, when we're finally able to stop scrabbling at our arms because there are imaginary spiders all over them. An interview with Valve’s Doug Lombardi has teased ever so slightly that one day we will all relapse: "We are not done with Gordon Freeman's adventures. I have nothing other than that to tell you today, but hang in there with us." Is this Episode 3 or perhaps even the mythical Half-Life 3?  All we know is papa has a scorching case of headcrabs and he needs his gravity gun! [via AusGamers]
