Konami released an update for Metal Gear Solid 5: The Phantom Pain today that adds new features to the game’s online competitive multiplayer mode, FOB missions, including the option to play as the sniper Quiet.

Players can now choose Quiet to infiltrate other players’ forward operating bases. In FOB missions, Quiet has extremely fast movement speed and can quickly close in on enemies with her dash move. Remaining still for a short period of time will activate her cloaking ability. Of course, Quiet is pretty good with a sniper rifle and can take long distance shots with minimal sway, thanks to her steady hands.
