Infinity Ward creative strategist Robert Bowling told G4 earlier this week that Call of Duty: Modern Warfare 3's public multiplayer playlists would soon be updated to include user-created game modes from the "Private Match" area for one and all to play on and earn XP from. A new post on the Call of Duty community site reveals that we'll be seeing the first new MP content arrive today!
A new "Community Playlists" menu will be added to the selection of public matches, though it doesn't appear to be live at the time of this writing. The first mode to be added is Drop Zone, a Private Match type in which two teams via for control of an ever-changing control point, much like King of the Hill. The twist is that whenever the point is held, choppers fly in repeatedly to drop care packages, which the Drop Zone-controlling team "owns." There are also no killstreak rewards in this mode beyond what you get from the Drop Zone.
There's also a pretty major tweak in store for Hardcore mode, a set of game types in which bullets do significantly more damage, the on-screen radar is turned off and, most importantly, friendly fire is active. IW will be flipping the switch on "Ricochet" for all Hardcore matches, meaning that any friendly fire damage taken will be directed back at the shooter. The announcement describes as the change as "a response to team killing." Take THAT, griefers!
The Community Playlist menu will become a new fixture of MW3's Find Match options. There's no word on when the next mode might be added or what it will be, but the plan is to continue highlighting Private Match modes, either the stock ones (which Drop Zone is) or particularly popular user-created ones.
