All of us here on the TF2 team have been asking to play Portal 2 for months now.

"Go away," the Portal guys told us. "You'll just try to put hats in it."

"Whaaattttt?" we said. "That'spsshhhh. If anything, we'll probably tell you to take some hats out of the game."

"There are no hats in the game."

After this, there was an awkward ten-minute silence while all of us on the TF2 team stared at the Portal guys, waiting for them to start laughing. Instead, they just told us to go away again. That's when we realized: with so little time left before release, we couldn't afford to waste any time playing the game. We had to fix it. Now. So late last night we snuck into the Portal 2 source code and copy/pasted some hats into it.

You're welcome, Portal 2 team.

Today, we pass the fruits of our clandestine game-saving labor onto you, the hat-loving public (or as you're more commonly known, the public). If you own any of the following hats in Team Fortress 2, you'll be able to equip them on your Cooperative Testing Initiative robots in Portal 2:

• Mann Co. Cap
• Prince Tavish's Crown
• Pyro's Beanie
• Fancy Fedora
• Master's Yellow Belt
• Tyrant's Helm

If you've been on the fence up until nowand who could blame youyou've finally got a reason to buy Portal 2. Courtesy of Team Fortress 2. The best game that Valve makes with a "2" on the end.
