Is This Valve’s New IP?

An avid PC gamer has apparently taken pictures of artwork in a developer’s office at Valve. If you take a look at the images below none of them look like they could be from a new Half Life game, but instead they look like they are from a sci-fi alien game. But anyways the images are below, courtesy reviewsonq. Let us know what is your take!

Let us know what you think in the comments below.

Edit: We have contacted Valve and are awaiting a response.
