Orange Box will include Johnathon Coulton track

Normally in a news article like this I'd start by outlining for all of you just what The Orange Box is, what it contains and how awesome it's likely to be. This time though I'm not going to bother about all that for two reasons. Firstly, everybody in the world knows about Half-Life. Secondly, it would take three times as long since The Orange Box contains three new games; Half-Life: Episode Two, Portal and Team Fortress 2.

Well, no, it actually contains five games if you count the original Half-Life 2 and Episode One. Six if you count the easter egg which Valve has recently let slip about.

According to Joystiq, Valve has revealed that geek musician Johnathan Coulton has also contributed to The Orange Box.

Coulton has achieved cult status in the geek community with songs like 'Code Monkey' and 'Baby Got Back', apparently. Honestly, I've never heard of the guy.

Coulton has apparently teamed up with the Valve design team to create a song which will be hidden somewhere in The Orange Box. General opinion is that the song will probably be about Zombies in one way or another.

So, what's your favourite easter egg or hidden feature of all time? Let us know in the forums, if you can find them.
