Stealth Techniques

Hold-ups

If you sneak up on an enemy undetected while holding a gun, press to hold them up at gunpoint.
Enemies are defenseless while being held up, but they will try to fight back if you give them an opening.

Looting Items

Press (without equipping a weapon) near an enemy who has been stunned or put to sleep to hold them and release the button to put them down.
By repeating this, the enemy may drop an item box.

Tactical Reloads

You are defenseless against enemy attacks while reloading a firearm. When you are running low on ammo, quickly press twice to switch out magazines faster, allowing you to reload without having to wait for the usual reloading process.

Run and Gun

If you hold down , you can run while holding your handgun or assault rifle.

Jump-out Shots

While against a wall corner or other location using Corner View, press with a weapon in hand to jump out from cover and ready your weapon. This allows you to switch quickly from hiding to attacking.
Grenades can be thrown while you are peeking from behind cover.
