CVG Half-Life 2: Episode Two, Portal, and Team Fortress 2 previews|Episode Two:

"The most intriguing prospect of Ep Two though is the setting - since forests, farmland and countryside generally aren't quite as constricting as the linear paths through barricaded streets and murky industrial complexes in which Freeman has made his name. Clearly, there'll still be a lot of this, chiefly an underground journey through mines and Antlion burrows, but much of this new instalment will take place in a far broader arena. You'll be really encouraged to get to know the lay of the land that you're covering, journeying back and forth between action hotspots as opposed to relentlessly pushing forward as you did in the Coast and Water Hazard sections of HL2; making decisions about which skirmishes to take on first and which places to make your stand."

Portal:

"Portal takes Prey's scripted portal dynamic and shoves it so far, far up its arse. I mean, in Prey could you magic up two portals on the floor then push a box into one and watch gravity bob it up and down in each of them? Has any game given such backhanded witty praise as an unseen AI chirruping "Unbelievable! You must be the pride of !" as you solve a puzzle?"

"At this point in my presentation the screen in Valve's boardroom flickers into life, and the new rendition of iconic TF map 2Fort appears before me. "We chose to do a kind of '60s sci-fi theme, and the reason for that was the exaggerated environments, the unrealistic weaponry and the notion of having one team just across the bridge from the other team." I nod. There are, after all, few international conflicts that revolve around two hangers that sit 100m away from each other. "Another reason we chose it was that thing of James Bond and the volcano with the secret lair underneath," continues Brown as we share a knowing You Only Live Twice 'Little Nellie' moment. "So it's seemingly simple, unassuming and non-threatening, but underneath it's hiding its intent, and so that again fits into this role of why team A is right across from team B."
