Venom Snake using Reflex Mode to take out an enemy soldier.
Reflex Mode was an ability used by Big Boss during the Ground Zeroes Incident, and by his phantom Venom Snake during the Phantom Pain Incident. When spotted by an enemy soldier, their perception of time slowed down, enabling them to quickly defeat the soldier and stop them from raising an alert.
Behind the scenes[]
Reflex Mode is a mechanic the player can use in Metal Gear Solid V: Ground Zeroes and Metal Gear Solid V: The Phantom Pain. Hideo Kojima's reason for including this is because the enemies in the two Metal Gear Solid V games can go anywhere in the area and are unpredictable. There is an option to turn this off and Kojima confirmed that the player will be encouraged to not use Reflex Mode and will get rewarded if they do not use it. It was first unveiled at the Ground Zeroes presentation for Tokyo Game Show by accident.
