Valve fansite ValveTime.net has posted what it is claiming to be concept art taken from Half-Life 2: Episode 3, the sequel that Half-Life fans the world over have pined for information on for almost six years.

The images are said to have been created back in 2008.

Now, seeing as this is a Half-Life related leak, you can be sure that most of you, ourselves included approach such leaks with unanimous suspicion. However, in this case, a number of Steam forum moderators are said to have confirmed the legitimacy of these images.

ValveTime are saying that the images have come from an aynonymous source from inside Valve. The images apparently show Alyx, the combine, a crashed helicopter in an Arctic location and even a depiction of Xen. Head over to ValveTime’s official Facebook for all the images, as their site is down as we speak. We have selected a couple of images and have posted them for you here below.

What do you think? Legit? Or complete BS?
