CS:GO went three to play and got a battle royale mode last week - but the surprises didn't end there, as players discovered a cryptic message which some speculated was an ARG to tease Portal 3. Despite the best efforts of CS:GO sleuths, however, Valve has since confirmed this is actually just an Easter egg - although it's still a pretty neat discovery.

But there are signs of change; today, New York's prestigious Museum of Modern Art announced the beginnings of a considerable video game exhibition.
Valve is planning to put its first hardware into beta sometime next year, noted Valve employee Jeri Ellsworth in a report by Endgadget.
The hardware division's goal is "to make Steam games more fun to play in your living room." To start with that includes Big Picture Mode, which makes Steam's UI more conducive to browsing with a gamepad on a TV, but eventually it would like to go beyond that and make mouse and keyboard games more accessible to the console crowd.
How it will do this is anyone's guess. Will it be a new hybrid controller, a console, or perhaps a real-life turret gun made by Lord of the Rings special effects gurus Weta? [Shown below.]
The world record time for a Portal speedrun has been demolished by a new attempt that completes the game in just 8 minutes 31.93 seconds.
An official Portal Lego set may be on its way after a fan-made prototype received the 10,000 votes required to be considered for production on the Danish blockmaker's crowdsourced platform Cuusoo.
This means that the set will go into review at the start of the next quarter in September. At this point, a "Lego Jury" comprised of designers, product managers, and other key team members will determine if it's a viable concept. This will be based on criteria such as playability, safety and fit with the Lego brand. This process could take several months.
If it meets Lego's standards and goes into production, it will take several more months while marketing materials, instructions and packaging are manufactured.

Last month EA's David DeMartini, who runs rival digital platform Origin, said Steam sales, which often see discounts of up to 75 per cent, "cheapen intellectual property".
Vowing not to copy Steam's popular 75 per cent off sales, DeMartini said: "The game makers work incredibly hard to make this intellectual property, and we're not trying to be Target. We're trying to be Nordstrom."
Steam Greenlight, Valve's new system for allowing the community to vote on what games get released onto its digital platform, will create fandom, the company has said.

On Valve's website sits a profile page, and on that profile page sits an entry for Left 4 Dead writer Chet Faliszek.

Valve has updated the PC version of its first-person puzzle classic Portal with an enigmatic patch which has set fans on a trail of code-cracking and puzzle-solving.
The patch notes for the update simply, but enigmatically, read: "Changed radio transmission frequency to comply with federal and state spectrum management regulations."
What it didn't mention was a new Steam achievement for the game called Transmission Received. Completing the achievement involves carrying a radio around the game and receiving broadcast interference noises in certain places.
The organisers of the Game Developers Conference have announced that Valve co-founder Gabe Newell is to receive the event's Pioneer Award this March.

Valve's Doug Lombardi has told Eurogamer that you won't see a new Portal this year.
EA has sneakily released a beefy patch to address problems with The Orange Box on PS3.
The 1.10 update is 128 MB, and unhelpfully has no associated documentation to outline the changes.
Early reports suggest friends not appearing on lists and certain accounts not connecting to the EA servers should no longer be a problem.
Valve has said it will be releasing the separate components of The Orange Box in shops from 11th April.
Portal end-credits song "Still Alive" (oh come on, you must know that by now) is set to join the ranks of downloadable tracks in Rock Band.

Valve has finally released The Orange Box on Steam!
Valve has started to pump up the volume along with the stereo and pre-load files for Half-Life 2: Episode Two and Portal.
Valve has made The Orange Box available to pre-order on Steam ahead of what is now a 10th October activation date - and those who pre-order will be able to play the Team Fortress 2 beta from 17th September.
Orange Box will sell for USD 49.95 on Steam, and pre-purchases will get a 10 percent discount on that price, as well as a free copy of Peggle Extreme.
The compilation release - which consists of Half-Life 2: Episode Two, Team Fortress 2 and Portal - is also being produced for Xbox 360 and PS3. The 360 version will launch at the same time (at European retail 12th October) while the PS3 version is due a few weeks later.
In light of recent chatter about Stranglehold having cost USD 30 million to make, we thought we'd ask Valve's Gabe Newell how much Orange Box ran to. "I don't know," he told us at Games Convention. "We don't track that."
Word on the vine of grapes is that Valve has narrowed down Half-Life 2: Episode Two, Team Fortress 2 and Portal's cluster-release to 9th October.
The date comes courtesy of Shacknews, who spoke to Valve about it yesterday. When we popped over last month they were saying October, so it would seem to tally with that.
If the games do emerge on 9th October on Steam and at US retail though, we'd anticipate a wait of a few days before they emerge in UK shops, which traditionally toss out new games on Fridays.
Remember Adrian Shephard? The star of Half-Life 1 expansion Opposing Force hasn't been seen since, although that hasn't stopped gamers speculating on the future of the US Marine Corporal who found himself caught up in the original Black Mesa research incident that propelled Gordon Freeman to fame.
