Chain Reaction Destruction

Go To

A trope seen in video games. Basically, a larger thing, be it a larger enemy, boss, an entire structure or sometimes even a planet, makes numerous smaller explosions scattered across its surface (often with regular time intervals) before finally making a big bang or just simply being destroyed.

Usually, mechanical constructions in Real Life don't have tens of parts that explode, especially at regular intervals. However, you might notice that many examples below are made from even less volatile material like concrete which isn't known to explode in real life at all. Some examples take it step further so now even characters made of meat and flesh can cause explosions in a similar manner, be it an alien or a pirate captain. Strangely, they often aren't carrying explosives or firecrackers with them either to justify these explosions.

It's also often observed that while explosions often appear in random places on the surface of the destroyed thing or character, they can also appear in the vicinity of the destroyed thing and not on the surface of this thing at all. Moreover, some of the exploding things themselves disappear right before the series of explosions occur, making you wonder how can explosion chain reaction occur out of thin air. That might forever be a mystery. Maybe the explosions happen because of Rule of Cool.

The origins of this trope are currently unknown but may have been initially used because of technical limitation of consoles. Making a big explosion with sprites only will bring a third generation console down to a crawl so several small explosions which appear at different time intervals, were used instead since it's much more resource-friendly to the console. Then it was noticed that it looked cool anyway and that's why we have it in games on much more powerful consoles.

The regularity of this trope is the most clearly seen in third generation and fourth generation video games with about every 16th NES game having explosions like these. After that period, the usage of this has been reduced slightly, but it's still almost always played straight since it is not very recognized trope. Usually, 2D games use chain explosions more often.

Subtrope of Stuff Blowing Up, often with Made of Explodium. They're also common in games where every enemy tends to explode.

More than 3 explosions counts as this trope.

Not to be confused with Disaster Dominoes.

Destruction after or with the series of explosions

    Action Adventure 

    Action Game 
  • Missile Command is the Trope Codifier of videogaming history. Part of the strategy is that even though you have a limited number of missiles, you try to destroy the missiles at the edge of your explosion, because their explosion can take out other missiles, causing a chain reaction of explosions. Since you get bonus points for unlaunched missiles, it also aids your score.

  • Capital ships and space stations in the X-Universe series suffer two or three secondary explosions, then one enormous flash that completely disintegrates ships and leaves a burned-out hulk behind in the case of most stations. Anything corvette-size or smaller explodes immediately in a small fireball, averting the trope. The explosions do no damage in the vanilla game, though various Game Mods such as Xtended add it.
    • Capital ships in X Rebirth will have dozens of explosions go through their hull, then a massive implosion followed by an explosion as the jumpdrive goes critical. Ships near the explosion take massive damage.

    • In The Phantom Menace, the Trade Federation ship explodes at random points all over its hull before engulfing the command section after Anakin puts two proton torpedoes into one of the reactors.
  • In War of the Worlds, Ray sticks a grenade into a tripod. The tripod then explodes repeatedly and falls over.
  • At the climax of Guardians of the Galaxy Vol. 2, Planet Ego goes out with a massive chain reaction after Groot's bomb explodes on the core.

Pinball

  • When you sink a ship in Black Rose, it explodes several times before sinking for good.

Real Life

  • Fireworks factory and fireworks or munitions storage explosions are some of the closest it's possible to get to this trope without deliberately setting it up.
  • This is how several real life aircraft carriers were lost during World War II (and how USS Forrestal was nearly lost after an accidental fire during Vietnam War). An aircraft carrier in wartime has a lot of explosive stuff lying around both on and below flight decks (bombs, fuel lines, bombed-up and fueled-up aircraft, etc.) If there is a fire, there is a good chance that fire would spread to these incendiary objects, start a chain reaction, and lead to catastrophic results.
    • Note that ideally, said flammable/explosive things are kept safely stowed away (preferably in protected areas away from each other), but certain operations necessitate moving them to more exposed areas, such as arming and launching aircraft, or moving ammunition from the magazine to the guns. Several Real Life examples of ships being destroyed due to this trope were the result of unsafe practices meant to more quickly move the process along (this was infamously how several of the Royal Navy's battlecruisers met their untimely end at the Battle of Jutland.)
  • The Deepwater Horizon/Macondo blowout and explosion is a modern textbook example of this trope as well as being a case of Disaster Dominoes:
    • The well casing cement fails, allowing wellbore pressure to rise beyond manageable levels.
    • The blowout preventer's annular fails to contain the pressure. The well blows out on the rig floor, venting wellbore contents.
    • The MGS (Mud-Gas Separator, also called a Gasbuster) fails to keep up with the volume of gas in the mud being pushed out of the well. This causes a fail-deadly situation as gas begins to build up around the platform, particularly around the wellhead.
    • Gas is sucked into the platform generator air intakes, causing generators to overspeed until they explode.
    • The fire flashes back to the wellhead.
    • The accumulated gas cloud on the drilling floor and surrounding the platform explodes. This entrenches the fire that will ultimately cause the platform to sink.
