Metal Gear Online has received a free update today that includes a new team mode for online gamers. The new mode entitled Team Sneaking involves an Attack & Defend style of play where one team will be invisible unless spotted (much like offline) and then will remain visible until the caution timer drops down. The object is for the stealth team to basically infiltrate and destroy their target while the defensive team prevents that from occurring.
On top of this addition a new mode of play has been added for all game modes in general. "Headshots Only" is a pretty self-explanatory mode and players who commit kills without headshots will be penalized. It's good to see additions to this side of the title in an under a month since release. There will be undoubtedly a lot more to come that will help make the online portion a very solid addition to the franchise.
