Pre-purchase Orange Box on Steam, play TF2 beta next week

Valve announced today that those who pre-purchase this holiday's über-value The Orange Box on Steam will be invited to the Team Fortress 2 beta next week. Beginning Sept. 17, those who bought the game can download and activate the TF2 beta. If that's not enough, Valve will also toss in Peggle Extreme, a special edition of the game that'll have themed Half-Life 2, TF2 and Portal content.

Those who purchase The Orange Box before Oct. 10 via Steam also get 10% off the $49.95 price on PC. Meanwhile, the console versions of Orange Box will both be the "next-gen price" of $60 -- although Amazon currently has the Xbox 360 version for $55 as part of a pre-purchase deal. The PS3 version was recently delayed. The PC and Xbox 360 versions of The Orange Box will be ready to peel on Oct. 10.
