David McGreavy is a gift that keeps on giving. The 2K senior producer is an avid collector of all things Valve. He has spent the past few years collecting bits and bobs from the company, including unreleased projects.
A few months back, McGreavy teased that he'd gotten his hands on a bunch of new Valve concept art. Now, he's finally found the time to scan and share some of them online.
The most interesting image is easily that of the slug-like creature found in the top left corner of an image alongside what we can only presume are other concept arts for Half-Life 2: Episode 3.
The creature's name, BreenGrub, might ring a bell if you're a Half-Life fan. Dr. Wallace Breen was a villain in Half-Life 2 who fell to his death after the destruction of the Citadel's reactor. Breen's only appeared in flashbacks in Episodes 1 and 2 since. We know from an Episode 2 recording and testimonies from former Half-Life 2 writer, Marc Laidlaw, that Breen will be in a different "host body" in Episode 3. It's safe to say that Breen didn't really have much of a choice where his conscious mind would land.
