However, enemies that are alerted have adrenaline coursing through them, and some will require more than one knife to take down this is especially the case for humanimals, which require one knife to kill if they are relaxed, but two to kill if they have been alerted.

In Metro Exodus, enemies that are unaware can typically be killed with a single knife anywhere on their body. They become even more deadly at Ranger difficulties, killing watchers in one hit, and even being effective against librarians, although a one-hit kill is extremely unlikely. One of the more useful weapons for stealth gameplay, as it has theoretically unlimited ammunition and is a one-hit kill for humans, lurkers, lesser shrimps and nosalises. However, if a throwing knife hits an ammunition pouch on an armored enemy, the knife may only detach the pouch, causing no damage to the enemy, but alerting him to your presence, as well as meaning the knife is harder to find. Generally, the knife can be picked up from fallen enemies, though they can be lost easily in scenery or if they hit a detachable ammunition pouch. Throwing knives can be found shortly after the Riga station and onwards, in Metro 2033, and are found after escaping the Reich concentration camp in Pavel, in Metro: Last Light. Throwing knives can be bought in every station that has a weapon vendor, but because of their re-usability, that should never be necessary they can be often found lying around in or around any place where hostile humans are present. Generally, the closer to the target the more damage you will inflict - with humans, however, the hit is always an instant kill, wherever on the body it hits. Despite this, many mutants can be killed instantly if you are hidden and they are not alert. It is not as effective against mutants as they usually come in numbers too great for just 5 knives to handle, (10 on ranger mode) and many have armoured shells that cannot be pierced by the blade. Furthermore, Artyom will often find himself completely out-manned and outgunned, meaning stealthily killing his enemies will give him a greater chance of survival than shooting on sight. The perfect weapon for this is the throwing knife it will kill your human opponents in a single hit from a sneak attack, and it is a silent weapon, meaning enemies killed by them will not be heard by nearby enemies, unless they are within earshot to hear the body dropping, or find the corpse. In the Metro, ammo for your other weapons can be, at times, scarce, thus creating the need for a weapon that can be used and retrieved multiple times.
