A few weeks ago a visitor to Valve's offices took a photo of a wall full of concept artwork for reasons unknown. Now PC Gamer's grabbed some close up images.
The 29 separate images, taken by PC Gamer during a recent visit to Valve's offices, are mostly of characters, some of which look alien.
There are also some vehicle concept art pieces in the picture spread as well.
No one appears to know what are these images supposed to be for. Episode 3? DOTA 2? Something completely different? Or is all of this just a red herring, as PC Gamer itself speculates?
Whatever. They're pretty to look at.
