REady, Bob? Ready mop and bucket? Let's wipe the floor with these guys!The handsome writer clicks on the Steam Store and types the word “zombie” into the search bar. Too many. He reorganises them by game only. Still too many. They’re everywhere. Surrounding us. An outbreak. It’s only a matter of time before — wait, what’s that groaning? Where is it coming from? He moves to his browser and checks his tabs. That wasn’t there before. He starts closing tabs down, isolating the infected tab: move Gmail, get away Reddit Aww, flee Katy Perry vs Aha. Just one more tab sits, keeping the outbreak from spreading. Slowly, uncertainly he clicks the ‘x’ on the Apple store tab and reveals the source: it’s the Contagion GDC trailer. (more…)

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.

-Removed a bad item cluster in the finale which was causing too many items to spawn.

Dead Air 3:

-Removed the ability to climb an electric box prop near the barricade in the construction yard. It should no longer be possible to skip the barricade event.

Blood Harvest 4:
-Widened the gap in the railing on the final bridge.
-Falling off the cliff or the final bridge is now fatal to both teams.

Blood Harvest 5:

-Fixed a case where AI infected would sometimes get stuck trying to mount the drain to climb up toward the start of the map.
-Consolidated items in the tank fight area at the halfway point.
-Altered tank fight area in the stream so that AI tanks don’t spawn in nearly useless/sitting duck locations.
-Removed one of the triage tents and replaced it with an open trash/storage area.

<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.
