The first playlist update for Call of Duty: Modern Warfare III has arrived, bringing with it a new "experimental" playlist featuring player outlines that help them stand out in the environment.

In this experimental playlist, enemies have a very subtle red outline around them. Beyond this, a blue outline has been added to all teammates across core multiplayer modes. Players can even seen teammates through walls if they are close enough.

Enemy outlines, as mentioned, are much more subtle and are not visible through walls. You can see examples of the changes in the videos further down the page from CharlieIntel.
