The Xbox 360 version of Team Fortress 2, included in 2007's The Orange Box, is set for a "massive update" that will include everything shipped on the PC version in the last year, Valve has revealed.

There's no firm date for the update, however. In a post over on the official Team Fortress website, Valve said: "We'll provide you with a rough date when we have one."

The post also details a number of changes to the Engineer and Spy classes, and reveals plans to import engine improvements from stellar zombie survival shooter Left 4 Dead into the Team Fortress 2 engine.
