Metal Gear Online players, you've now got two new additions to your Metal Gear Online gameplay. One is a new game mode, called Team Sneaking. This expands on the original "Sneaking" mode, and instead of just having Snake invisible, makes one whole team invisible. The other change is that hosts now have the ability to toggle "Headshots Only", which will punish any kill that's not a bullet to the head.
