There are some new game modes that have been added to Call of Duty Modern Warfare 3.
This is what Infinity Ward posted:
Friday, December 16th, we’re updating the playlists on Modern Warfare 3 to introduce some new game modes as well as change up some existing ones.
The biggest change you’ll notice is the addition of Community Playlists. This is where we will add popular or unique private match modes to the public playlists, so you can start ranking up on them! The first playlist changes for Modern Warfare 3 multiplayer are listed below:
Get to the drop zone to earn points, the first team to 7500 points wins the round, but thats not all. As long as the Drop Zone is occupied, a care package will drop every 15 seconds, which ever team has the most members in the drop zone at that point “owns” the care package, but anyone can steal it. This is the only way to earn air support in this mode, all other pointstreaks are disabled. You’ll earn 20 points per team member, for every second they’re in the drop zone plus 20 XP individually for your time spent in the zone. Kills are worth 50 XP in this mode.
Custom Settings: Pointstreaks (besides those obtained through in-game care packages) are disabled.
Hardcore HQ Ricochet
We’ll be adding Hardcore Headquarters to the Hardcore Team Tactical playlist.
We’ll be converting all Hardcore modes to Ricochet variant as a response to team killing. This means, any friendly fire, is applied to the attacker, rather than the victim. So choose your shots wisely and any attempt to team kill will simply kill yourself.
