Valve employees were asked “What can we expect in Half-Life 2: Episode 3?” in a recent interview. The Half-Life 2: Episode 2 project lead David Speyrer answered: “We don’t know entirely what’s happening in the next episode, but we’re gonna figure it out!” he laughed.
He then further explained: “There are always things we want to do that we can’t because of the constraints of either the story or the arc we’ve laid out for the gameplay - or just time. So we shelve them and carry on. Ideas fly around here quite a bit, so we have this huge laundry list of things to try [from previous Half-Life 2 games] for the next thing… [Half-Life 2: Episode 3].” — Via PCzone
In case you’re wondering what will happen after Episode 3 is released in either 2008 or 2009. Developer Valve said it will be the last episode in the currently planned story arc, but it will not be the end of the Half-Life franchise, so Half-Life 2: Episode 4 or in a way Half-Life 3 might be entirely possible.
Artwork from Half-Life 2: Episode 3 — like the piece shown below — will be at E4All 2008 as part of the Into the Pixel exhibit that runs from October 3-5.
This concept art shows Half-Life protagonist Gordon Freeman within a large Citadel-like environment as an evil Combine Advisor hovers over his head.

Here are the details…
TITLE: Advisor;
GAME: Half-Life 2: Episode 3;
ARTISTS: Ted Backman, Jeremy Bennett, Tristan Reidford;
PLATFORMS: PC, PS3, Xbox 360.
Perhaps this is the same environment where the 2007 concept art of the Aperture Laboratories ice breaker / research ship, the Borealis, takes place. The Borealis contained Aperture’s version of the teleportation technology (different from Black Mesa’s) but the ship was never commissioned and disappeared with all hands and parts of the dry dock from the shipyard, until appearing in the ice locked northern seas at the end of Half-Life 2: Episode 2.

UPDATE October 14, 2008: Valve marketing director Doug Lombardi has said in an interview with Kikizo that they “may [announce Half-Life 2: Episode 3] at the very end of the year.” Although he cryptically added it may take a while longer for it to come out, by saying that “The next time you play as Gordon will be longer than the distance between HL2 to Ep1, and Ep1 to Ep2.”
UPDATE June 10, 2009: Valve co-founder Gabe Newell was asked on the G4 TV channel why we haven’t heard anything about Episode 3 at E3 2009? To quote Gabe’s answer:
“I get a ton of email everyday saying why aren’t you talking about Episode 3? And there are very good reasons why we’re not talking about Episode 3, which I can’t talk about yet, but I will. So, I think there’s frustration there and I’m not somehow going to say that that’s not legitimate or length isn’t a concern or regularity. The speed with which these updates are coming out, people say, “Hey, gee, these episodes are supposed to be shorter and you take 25 years to ship each one.” So, I don’t wanna somehow dismiss those, or sort of throw them under - but I think we’re in much better shape than would have been, in terms of our ability to move stuff, technology, products, uh, forward faster by changing how, ya know, being different than, ya know, there was Half-Life 2 and then there was post-Half-Life 2 in terms of how we were approaching these things and yea, I think that we’re overall pretty happy without somehow dismissing the legitimate complaints that people should have towards us. But, we’re happy with that choice that we made.”
After Gabe was asked if we’ll hear any further details (or video) about Episode 3 by the end of 2009, he continued talking without giving an answer:
“Just so you know, the thing to me, that feels right, is the rhythm that Robin and his team are operating with. It’s like watching the reaction of that community, watching their ability to respond, looking at the quality of the work they’re getting with the length of those development cycles. They’re having a great time. And I think it shows on the other side, right? I mean, they were just giggling so hard when they were changing the buttons in the movies to say “leak video.” Do you remember the big screen with all the buttons? And they were like we have to put “leaks video” into that thing before we release it. They were just like cackling away. What should have been like, pretty demoralizing and stressful was for them, “Oh, this is no big deal.” So, yeah, people get the idea.”
UPDATE August 7, 2009: Valve co-founder Gabe Newell and other Valve writers have been researching sign language, for use in Half-Life 2: Episode 3, through a deaf people focus group. He explains how sign language might be implemented into the game and story. To quote: “The idea is that Alyx, before she met Gordon Freeman, had a crush on someone who was hearing impaired, so she taught Dog how to sign so she could practice. Something happened, maybe, the person is off fighting the Combine someplace else, but that’s why she and Dog would start signing with each other when they wanted to communicate without making noise, or communicate without other people knowing … That’s the idea of bringing signing into the game. It gave us the excuse to build the technology for signing.”
You can watch the full 25-minute-long focus group session split into three videos on Samuel Sandoval’s Youtube page. The above quote comes from the video titled Gabe Newell with Deaf Character - Part Two.
“”"”There won’t be a half life 3, you’re already playing it. Episode 1 2 and 3 make up Half Life 3.”"”"
I recommend you do some more research I am not going to give anything away but that idea was pre-concieved by valve before episode 1 even came out, and if you add what’s going on in the story and look up valve interviews after episode 2 its very likely for a Half-Life 3
Actually episode 1, 2 & 3 would be Half Life 6
Half life episodes 1, 2 & 3 DO NOT amke up Half Life 3. They were release to continue the Half life 2 story arc. Half life 3 would start a new story arc. and Episode 3 is supposed ot be logner than the time between HL2 to episode 1 & EP1 to EP2. It is going to be REEEEAALLY long. If you don’t understand i would be glad to type slower to you
The reason E3 is taking longer than expected is because of the quality its going to be and because they are probably about a year or more into the production of HL3 so not 100% of their resources are on it.
Would you rather them focus on E3 so theres a nice 4-5 year gap in between?
[Mod edit: E3 2009 is scheduled for June 2-4.]
IDK what the big deal is with the whole HL2 ep. 1-3 being HL3 or not being HL3. If you google a few interviews from the developement team, you’ll find out that the story arc is going to be completed (for HL2 ep. 1+2) with ep. 3, and you’ll ALSO find out that there is another story being created as well!!!
Who really cares what it’s called; as long as Valve puts out another AMAZING Half Life game.
So, they’re gunna finish the HL2 ep. 1-2 story with ep.3 AND make another HL game!!!
I’m just worried about HOW MUCH LONGER I GOTTA WAIT TILL I CAN PLAY!!!
They are not going to end with half life 3. valve is simply making to much money to do that. I hope half life 3 explians G man. But i also thought at the end of eposode 2 every thing ended, the combine, the giant explosion and the war. Now its the stop of zombi things.
There are so many aspects of the story that still need to be covered in order for there to be adequate closure that could possibly bring the Half-Life series to a true stopping point. The citadel being destroyed leaves only remnants of combine to be dealt with, primarily the advisers. The humans need to rid the world of the “infection” the various head-crabs and zombies. The resistance needs to create a true government and begin re-building, once finally away from the “alien” control. My main question is, how far are they gonna carry this game before a new engine is created?
So basically all this hype means there is going to be a HL3, we all know theres an epi 3 in production. we all know its gonna talk longer than the time betwee hl2 and epi1 and epi 1 & 2, but realistically are we looking at the end of 2010 maybe 2011 before we see Epi3 launched?
Ah i want another halflfie game so bad
I really want hl2 ep3!
