History Main / BossWarningSiren

[[folder:Massively Multiplayer Online Role Playing Game]]

* ''VideoGame/{{Twinbee}}'', possibly the UrExample, has a buzzer warning of an approaching boss.

* Pick a fight with a [[BossInMookClothing high-level unique enemy]] in ''{{VideoGame/Xenoblade}}'', and your party memebers will spout warnings that seem to be [[WhatTheHellPlayer meant just as much for the player]] as for the party leader. Some examples:

* The shoot-em-up genre ''loves'' this trope. See [[https://www.youtube.com/watch?v=Tly-yvSNoEg this]] compilation video for some of the better-known ones.

* ''VideoGame/{{Undertale}}'': During the final boss of the Neutral Route, [[spoiler: [[EldritchAbomination Photoshop Flowey,]]]] a warning siren will sound before [[spoiler: Flowey uses the special attack of one of the six human souls.]]

* Indie video game [[http://www.pixelprospector.com/chalk/ ''Chalk'']] has the word "WARNING" flash on screen and an opera singer singing "oooohaaaahAAAAAH!" for it's boss siren. The last stage includes the siren at the start of its music, which is appropriate since it's a boss rush.

* ''Super Earth Defense Force'' uses DramaticThunder to herald an end stage boss. Even in locations where it wouldn't make sense (e.g. a cavern, the vacuum of space, or the alien base interior).

* ''[[VideoGame/{{Touhou}} Touhou Project]]'': In ''Subterranean Animism'', Utsuho Reiuji, the [[ILoveNuclearPower nuclear-powered]] [[RavensAndCrows Hell raven girl]] (and final boss) of the game, has the distinction of prefixing each of her spell cards with klaxons while the text '☢ Caution !! ☢' flares on-screen.

* ''VideoGame/NierAutomata'' has a warning card accompanies by a klaxon whenever a Goliath class machine is detected. These range from machines the size of a house to machines the size of a skyscraper.

* ''VideoGame/{{VVVVVV}}'' has a screen named "The Warning". One tunnel, no spikes, ''eight checkpoints in a row.'' It leads into one of the hardest sections of the game.

* In ''VideoGame/TheAngryVideoGameNerdAdventures'', the "Boo! Haunted House" stage parodies the NES adaptation of ''VideoGame/ANightmareOnElmStreet'' with the warning ''BIMMY'S©™ COMING!''.

* From ''VideoGame/Disgaea2CursedMemories'' onward, whenever a Pirate group is due to arrive in the [[RandomlyGeneratedLevels Item World]], the screen will flash red as a siren plays. ''VideoGame/Disgaea5AllianceOfVengeance'' even has a '''WARNING''' flash up on screen.
** ''VideoGame/DisgaeaDimension2'' is the only exception, as Pirate Groups tend to appear on the floor at the very beginning of that map.

** ''Anime/PuellaMagiMadokaMagicaTheMovieRebellion'' also has this during the movie's climax, where a very similar countdown indicates [[spoiler:Homulilly's]] attack. Coupled with BossSubtitles in runes.
* ''WesternAnimation/StevenUniverse'' gives a ShoutOut to the ''Darius'' example above, as it seems that the ship Lars and the Off-Colors steal is equipped with an automatic warning system identical to the "Warning" display from ''Darius,'' and Rhodonite, acting as a BridgeBunny, shouts "a huge battleship is approaching fast."

[[caption-width-right:320:In case the ominous, interlocking double doors you took to get in here weren't enough of a clue.]]

* "[[VideoGame/DonPachi WARNING: THIS IS NOT SIMILATION. GET READY TO DESTOROY THE ENEMY. TARGET FOR THE WEAK POINTS OF F**KIN' MACHINE. DO YOUR BEST YOU HAVE EVER DONE.]]" ...And in the sequels: "You are approaching the target of attack. The mission starts now! Are you ready?", "Watch out! Watch out!", and "An unidentified battleship/unprecedented tremendous force is approaching!"
* ''VideoGame/DangunFeveron'' brings us "[[AnnouncerChatter HEAVEN IS HERE]] [[LargeHam INSIDE MY SOUL!]]"
