It took a while but the highly anticipated Collection DLC Pack for the PC version of Modern Warfare 3 is now available and features 4 Multiplayer/Survival Mode Maps & 2 Special Ops Missions. In addition, Activision released an update for the PC version of MW3 that adds community playlists: Infected, FFA Gunplay & Drop Zone. Those playlists were added to the console versions a while back and were missing from the PC version. Thankfully, the PC version is currently up-to-date with the console ones, so good news to all MW3 PC fans.
The DLC is priced at 13.99 euros and those interested can purchase it from here.
