Knowing that we always need more Portal, Valve is now planning on releasing all the music from both games in a fancy four-disc collecter's edition.

The Songs To Test By: Collector's Edition comes out October 30.

Remember this week's real-life Portal Turret? Well, Valve posted another video revealing the origin of the device -- legendary New Zealand effects company WETA Workshop. And you've got to see their amazing Aperture Science packing crate.

It may not have ballistic capabilities, but this otherwise fully-functional Portal turret might just kill you with cuteness.

And no, this one-of-a-kind unit is not for sale. It was posted on the Valve Store's own Facebook page, presumably sitting in the offices to guard development of Half-Life 3.

After YEARS of fan-fueled development (eight!), Half-Life remake Black Mesa is here at last, and totally free!

Experience the original adventures of Gordon Freeman with a beautiful 2012 facelift, and the official blessing from Valve, which gave Black Mesa a Steam Greenlight a few days ago.

Download on Steam, or from the official site.

With a beta starting later today, it's time to brush up on Steam's all-new Big Picture mode, designed to make you throw away your xbox and take a bat to it, Office Space-style.

Because it's Steam. On the TV. Did you see how sexy that virtual keyboard looked?

All of the rumors are true. Team Fortress 2 will have a six-player Horde-style co-op mode, titled Mann vs. Machine.

The best part? It drops on August 15, just a couple days away.

A dedicated fan of Team Fortress 2 has compiled a video full of hints at Valve's new M. V. M. mode, something that has been secretly teased since 2010.

After the video was posted, Valve added fuel to the fire with the latest TF2 comic, Blood Brothers. It looks like a robot battle is in store for the near future.
