* The intro to ''Film/TheSumOfAllFears''.

* A Creator/ChrisClaremont ''ComicBook/FantasticFour'' issue started with Ronan the Acccuser taking out a set of the foursome's robots.

* While not actually the opening, in ''WesternAnimation/KungFuPanda'' we're introduced to the real Furious Five in a battle where they attempt to take out Shifu. They fail, badly.

A common variant is to begin [[FakeActionPrologue in the middle of a battle]], fighting against a formidable foe. Everything seems normal until [[AnyoneCanDie someone dies]]. [[ProsceniumReveal The simulated nature of the battle is revealed]].

* In ''WesternAnimation/ToyStory2'', we see Buzz Lightyear in a dystopian battlezone, finally reaching and fighting [[BigBad Zurg]]. After a brief fight, Buzz gets ''The upper half of his body blown to smithereens''. Then some Game Over text pops up, showing that it was just a video game played by Rex, and the "real" Buzz is still fine. Repeated more obviously in ''WesternAnimation/ToyStory3'', as well as in ''WesternAnimation/MonstersInc''.

This is similar to the BatmanColdOpen, only it's used [[TheTeam for teams]], particularly the Comicbook/XMen. Usually depicted in a training room situation, this trope often sees a team practicing for combat, using [[AttackPatternAlpha various strategies barked out]] by their [[StandardizedLeader Strait-Laced Leader]]. The scene is designed to have each member show off their particular abilities -- be they mutant powers, or cool gadgetry or weaponry -- as well as [[EstablishingCharacterMoment reveal some aspect of each member's personality]] through short quips and pithy comments.

* One Literature/JamesBond novel opens with our hero apparently exchanging gunfire in a dark alley. Turns out Bond is on a firing range, trying out a new target rigged with a blank-firing gun to better simulate combat conditions.

* The [[UnwinnableTrainingSimulation Kobayashi Maru]] scene from the beginning of ''Film/StarTrekIITheWrathOfKhan''. Once the ''Enterprise'' is done for and Saavik gives the abandon-ship call, the alarm slowly deflates and the main viewer opens for Admiral Kirk to walk in, revealing that it's the Starfleet Academy Bridge Simulator.

* The [[UnwinnableTrainingSimulation Kobayashi Maru]] scene from the beginning of ''Film/StarTrekIITheWrathOfKhan''.

** ''Film/NeverSayNeverAgain'' has Bond rescue a beautful woman being held hostage. Instead of RescueSex, she stabs him as she's suffering from StockholmSyndrome. Cut to Bond being chewed out by M, who sends him to a health clinic to get him back into shape after failing this training exercise.

* The ''WesternAnimation/LegionOfSuperHeroes'' cartoon used this for the first season finale's cold open.

** The main story thread of "Parkour Jam Hooligans"[[https://whateley.academy/index.php/story/parkour-jam-hooligans]] opens with [[DrillSergeantNasty range instructor]] [[BadassNormal Erik Mahren]] being chased by someone vastly more powerful. This turns out to be a simulation, used as a demonstration of CombatParkour for a Survival class.
