Upcoming Valve games Dota 2 and Counter-Strike: Global Offensive will support the Razer Hydra PC motion controller.


Motion gaming support has been added to over 250 of the most popular games on Steam, including Left 4 Dead 2, Half-Life 2 and Team Fortress 2, via creator Sixense's MotionCreatorTM 2.0 software.


Steam users will get motion control updates for current and future titles automatically from now on. A new in-game overlay lets you view control maps for the Razer Hydra as you play.


The Razer Hydra uses an electromagnetic field, via a base station, to track hand movements as you hold two motion-sensing controllers, both complete with thumb sticks.


We first heard of the Razer Hydra Valve love affair early last year, when we discovered those who owned the Razer Hydra were entitled to exclusive Portal 2 content.

Portal Gun 3
We've seen some impressive fan-made Portal guns in the past, but they've been rare, costly one-off projects. Valve are giving us the chance to get hold of our own Aperture Science Handheld Portal Devices without having to burn ourselves horribly putting together an injection mould. Joystiq mention that, at Valve's request, toy manufacturers, NECA have put together a life-sized Portal gun. It'll hit the shops this summer with a $130 price tag attached.

There will be lights and those lights will change colour, but will it make the "pwung" noise? There's only one way to find out, and that's to buy at least five. Perhaps ten. Maybe more. More. MORE.

NECA will also be releasing a line of Left 4 Dead, Team Fortress 2 and Half-Life action figures, a few of which were shown off at the NYC Toy Fair. The Team Fortress 2 wiki has a snap of the new figures, you'll find that below along with a few shots of that Portal gun. Baggsy the Heavy.

<b>Hard Eight!!</b>
Double the specials, quadruple the fun!

Face eight Special Infected at one time, this is double the standard number! And if that wasn’t trouble enough, we also increase the spawning frequency so it is raining Specials.

Why aren’t you going to give it a try? Scared?

<b>More Cold Stream</b>
Today we are releasing some bug and exploit fixes on the PC for Blood Harvest.

We have to thank everyone for their feedback and help catching these issues and making the campaigns better but we want to give a special thanks to Tabbernaut from the Steam forums for providing a concise lists of issues.

We still have a few minor fixes and performance improvements for the Cold Stream Campaign. We are going to be releasing those changes in a few weeks as the final build for the DLC.

On the 360 side we have been making some additional performance improvements. The finale section of Cold Stream in particular was a sticky area to pull off. Not only do we have to worry about view distances but the way the common infected move and navigate areas.

One of the results of our extensive performance tuning of the Cold Stream campaign is that we will be writing up and sharing some information with modders on improving the performance of their campaigns.

So enjoy Hard Eight and in a few weeks we will have another content update as we prepare Cold Stream to go into the Xbox 360 certification process.

The Half-Eaten Valve Art of Peter KönigPeter König is a concept art legend. Over the past quarter of a century his creature designs, sculptures and animation work have been featured in blockbuster hits like Jurassic Park, Starship Troopers and Cloverfield.


Which is all well and good, but he's also spent the last four years working as a concept artist, modeller and texture artist at Valve, where he's lent his talents to the Left 4 Dead series, Portal 2 and DOTA 2.


While there sadly aren't any images from Portal, and only one from DOTA 2, König's Left 4 Dead stuff is a treasure trove of the walking dead, rotting flesh and rejected designs for special infected that involved shooting rats out of a zombie's stomach.


You can see a nice collection of König's body of work, both in games and cinema, at his personal site.


Fine Art is a celebration of the work of video game artists. If you're in the business and have some concept, environment or character art you'd like to share, drop us a line!
