Defense (Metro 2033 Level)

Defense' is a level that takes place after "Depot". It involves a last stand with the surviving members of the Children of the Underground who are trying to defend Hole Station during the Hole Station Massacre, and Artyom's journey through the remains of the station.

Overview
The level begins with the player making it to the Childrens' frontline. Soon after, a battle will commence after a series of sonic attacks, which will take out some of the lights and then knock Artyom out. Upon waking up it becomes apparent that more soldiers will have died, and that the oncoming nosalises are very near. The battle will end with another huge sonic blast, rendering everyone unconscious again. Sadly it's impossible to save anyone, no matter how many nosalis the player kills as the shockwave kills the remaining soldiers. Once awake, Maxim Komarov will give Artyom his recording and a mission. By accepting Maxim's mission, the player will gain a positive moral points.

Proceeding through a tunnel, the player will find dead soldiers and nosalises, along with numerous lurker holes. With their occupants nearby, this environment will be more dangerous than any other shelter Artyom encountered before due to the presence of traps and toxic gas. After some wandering the player will begin to hear the crying of one of Hole's last survivors nearby, which is the end of the level.

Trivia

 * Maxim's name is revealed when the player broadcasts a message to Polis during the "Outpost" level.
 * According to the Moscow metro map, this station is named Paveletskaya (Zamoskvoretskaya Line). However, the game's station architecture is different from the real station.
 * Additionally, in the Russian version of the game, this mission is called Paveletskaya.
 * "Defense" was one of the first levels of the game shown publicly. Pre-alpha footage with very basic textures, sounds, models and animation shows the big difference between the alpha and the finished retail game.
 * It's possible that Hole Station had some kind of relationship with the Red Line, as there are a number of people in the station who wear the same type of armor as the soldiers of the Red Line. Alternatively these armor-sets could simply be the universal uniforms, worn by members of Hansa (which Hole is part of) as well.
 * Also, one of the soldiers of the barricade wears the same jacket as the Red Line officials.
 * There are several alternative route in Hole Station, they usually lead to extra supplies and a positive moral point.
 * Despite being a shelter, many areas in the Hole station will need a gas mask to survive. It's possible that the poisonous gases filled Hole Station during the mutant attacks.
 * Throwing knives are good to take out lurkers, as it only take one hit to kill them. Not recommended for those who cannot aim properly, or have difficulty aiming in ranger mode (without crosshair).
 * If you took the Heavy Automatic Shotgun from Andrew's room in "Armory", this level will be much easier since there are swarms of enemies and, as they get right up in your face, a shotgun blast will put them down easily. Also, with 20 rounds per reload, you should not have too much trouble.
 * In Metro 2033 Redux, this and the "Child" chapter are merged into a single long level.

Bugs

 * If you use a medkit the moment you become knocked unconscious, you will not be able use your guns/pick up items when you wake up.
 * When the sonic attack hits the crew, Maxim doesn't seem to black out, nor seen recovering after Artyom and the others have regained their consciousness.
 * If you activate the night vision goggles during the first sonic attack, Artyom will attempt to remove them during the final sonic wave. This will interrupt the animation that renders you unconscious; this will also disable all sound and disable the HUD, along with your ability to move as well as some other buttons.
