Original story: Valve has announced that the first major update to the PC version of its hit multiplayer shooter Team Fortress 2 will go live tomorrow morning at 11 AM PST.

The free update adds the new vertically-oriented map "Badlands," a reworking of a classic TFC battleground. Three previously released maps--Dustbowl, Granary, and CTF_Well--will also receive performance and gameplay tweaks.

In addition to map changes and additions, the patch will include further improvements to networking and graphical performance, player statistics, and Source TV. A full list of the changes can be found here.

Valve made no mention in its release of the forthcoming unlockable items or the previously-announced Goldrush map.
