Infinity Ward has released a patch for the PC version of Call of Duty 4 that fixes a few minor issues and adds a Christmas bonus, just for fun.
The patch, v1.4, fixes some bullet accuracy issues for all weapons, improves the server browser, and beefs up mod support. You can find a complete list of features here.
The above video showcases the patch's Christmas present to CoD players: "Winter Crash," a holiday version of the "Crash" multiplayer map. Candy canes and colored lights make deathmatchs so much more festive, don't you think?
