Remember when you first finished Half-Life 2: Episode 2? The excitement? The shock? You were ready to set out with Alyx at your side, ready to show those alien bastards who's boss. The trilogy, and with it, the Combine's rule over Earth, would end soon.

Except it didn't. At the time of this writing, almost five years have passed since the supposed release date of the final installment in Gordon Freeman's saga. Half-Life 2: Episode Three was slated to arrive Christmas 2007. It didn't. As the weeks and months went by, confused fans tried to glean whatever information they could from Valve, but, by and large, they were unsuccessful. The company remained silent.


In this Kotaku Timeline, we follow the fans' process of dealing with Valve's silence, cataloging their forays into leaked code, and their communications with the developers. We detail the ways the gaming press interacted with Valve over the years, and list what little has been revealed. In addition, we will keep watch over the game, and take note of any events, good or bad, in the months and years to come.

There were no mentions of the final episode—called Half-Life 3 by some—between 1999, when Valve registered the domain, and 2006. But then, announcements were made, and names were dropped. And so this is where our timeline begins...

April/May—Gaben and episodic gaming

GTTV interviews Gabe about a variety of things, managing to squeeze in a question about Episode 3. (Thanks, commenter Cursed Frogurt!) Transcript below.

GTTV: Episode 3. What do we know about it? What can you tell us?

Gabe: From our point of view there's enough newness in there that we want to sort of spring it on people and say "here's a bunch of things you've never seen before" — we have multiple of those.

GTTV: And that's graphically, or in terms of the gameplay, or...

Gabe: There's stuff that visually hasn't been in games before, and there's certainly a bunch of game elements, on the order of Portal, that have never been done before.

GTTV: So even better than the portal gun?

Gabe: Oh yeah.

GTTV: Really? New gameplay paradigms?

Gabe: Uh-huh. I think that we're really happy with how the Orange Box did, and we'd do an Oranger Box next time, certainly.

August 12—Gabe talks to Steamcast, but doesn't have much to say

Steamcast, a (now discontinued) fan podcast for all things Valve, nabs an exclusive interview with Gabe Newell, who briefly talks about why there's been no Episode 3 news. You can read a transcript of the relevant segments below.

Steamcast: Alright, first question: this is one of the most commonly asked questions that we had received and we've tried to format it into something you might be able to answer: you'd kept Episode 3 under incredibly heavy wraps thus far; we'd like to know why have you chosen to adapt such a reclusive approach this time around, as opposed to previous releases. Was it based on the reception you'd received about letting out too much info prior to Episode 2, or just something completely different?

Gabe Newell: I think that what's going on, you know, we're sort of always experimenting, we're always trying out different kinds of things, and that has positive as well as negative consequences for ourselves and for the community—so if you look at our different products, we're trying out these different rhythms. (Ed.: Here Gabe talks about how Valve handles updates for Team Fortress 2 and Left 4 Dead.) Right now, the Half-Life 2 episodes themselves are on a third sort of rhythm, and, you know, we think it makes sense for the product and for what we're trying to do there. The reason that we're not talking about anything is mainly that we don't have anything to say; it's not like we decided we released too much information, it's just that if we had information that we were in a position to deliver to people, we would—and right now we don't have anything to say about it. It really is a consequence of these different rhythms to release schedules we're trying out. (...) So, Ep 3 is sort of victim to our willingness to experiment, and as soon as we have stuff that we're ready to say about Ep 3, we will.

Steamcast: Alright, fair enough.
