Piling on to previous leaks, Counter-Strike co-creator Minh Le said in a new interview that Left 4 Dead 3 is in development and it is coming along well. Speaking with goRGNtv, Le--who no longer works at Valve--said, "It wouldn't be any news if I said yes, I saw it. It looks great."

"So I was really excited when I saw that. I was like 'Wow, this looks great.' I really enjoyed Left 4 Dead," he added. "It was just one of those games that really changed the industry because I think at the time there weren't many good co-op games, so it was like, 'Yeah, this is a great co-op game.'"

2008's original Left 4 Dead was developed by Turtle Rock Studios, which has since split from Valve and is working on Xbox One, PlayStation 4, and PC game Evolve. Left 4 Dead 2 was released just a year later in 2009. Though rumors have abounded about a third installment in the series, Valve has not said anything official on the matter, and the company was not immediately available to comment today.

Also in the interview, Le teases that another much-anticipated Valve game--Half-Life 3--is indeed in development and he's seen concept art for it.

"There's like a laser sight on my head right now. I don't know if I can talk about that, to be honest. I think it's kind of public knowledge that people know that it is being worked on," Le said about Half-Life 3. "So if I were to say I've seen some images, like some concept art of it, that wouldn't be big news. But I guess I could say that I did see something that looked like kind of like in the Half-Life universe. It wouldn't surprise anyone if I said 'Yeah, they're working on it.' So I mean, to go out on a limb, I would say yeah, I did see some concept art for Half-Life 3. Somebody's knocking on my door right now [laughs]. It seems like old news. I think everyone kind of knows that it's being worked on."

Le's latest project is free-to-play shooter Tactical Intervention, available now on Steam. He didn't like the idea of making a free-to-play game, but the business model choice was not his to make, he said in a recent interview.
