These days there was some talk about a new set of maps for PC version of Call of Duty 4: Modern Warfare, and interestingly enough, it is supposed to be sponsored by Nvidia. This sponsorship will enable COD 4 owners to download these new maps for free, whereas console users will still have to pay for them.
The new set of maps includes 4 new multiplayer maps: Broadcast, Chinatown, Killhouse and Creek.
With the maps, players will be able to download the latest PC version patch, with fixes for new maps, certain bugs and a couple of new options.
This new set should be online on the 5th of June.
