Patch 1.6 has been released for the PC version of Call of Duty 4, and the Variety Map Pack is finally available to mouse and keyboard gamers - for free!
The Pack includes four maps; Creek, Chinatown, Killhouse and Broadcast. The last one, in case you hadn't guessed, is based on the wicked single-player level in the television studio.
The rest of the changes in the PC patch are a bit mysterious for now, although it's confirmed that 1.6 adds "Hardcore and oldschool server browser filters" and a fix for Denial of Service attacks.
Infinity Ward revealed this morning that the Xbox 360 map pack has been purchased by over 1.5 million players, which must've made them a lot of money.
