A cross between EscortMission and HoldTheLine where you're staying in one place and protect a stationary object or NPC while enemies pour in and attack your charge. Usually, you either have to protect them for a specific period of time, or just kill all the enemies.

It doesn't have to be one object. Sometimes it's an array of objects, and if a certain number are destroyed, you fail.

Tend to be easier than classic {{Escort Mission}}s, since you do not have to worry about the [[ArtificialStupidity idiot escortees]] blundering into danger. And apparently trying to make you think TheComputerIsACheatingBastard or AIIsACrapshoot.

See also TowerDefense games, where you're generally tasked to protect a stationary object.

[[folder: Tabletop Games ]]

* Basic ''TabletopGame/DungeonsAndDragons'' adventure [=IM1=] ''[[http://en.wikipedia.org/wiki/The_Immortal_Storm_(module) The Immortal Storm]]''. A {{PC}} must act as a defender against the attacks of Spectral Hounds as his Hierarch uses an artifact to stop the title storm.

[[folder: Video Games ]]

* ''VideoGame/{{Prototype}}'' has you protect a room blocked by a reinforced glass barrier while an ally works there and later a deployed toxin pump designed to flush out underground infected.
** Interesting variant would be the collection of biomatter outside of a hive that the military shows up to destroy. As long as you collect quickly enough, you may not even have to touch the military due the pair of hunters defending the hive against both them and you.
** ''VideoGame/{{Prototype 2}}'' has one where you will need to defend a downed helicopter with a plot-important person inside. In this case, considering you intend to [[spoiler:consume him]] anyway, it makes little sense that you can't just pluck him out and get it over with instead of defending him first.
* Near the end of ''VideoGame/HalfLife1'', where you're about to teleport into the AnotherDimension, you have to prevent aliens from killing a scientist who's busy setting up the teleporter until he finishes his job.
** Near the end of ''VideoGame/HalfLife2'' Episode 2 you have to protect White Forest Base from being attacked by striders.
* Pops up a few times in the tactical strategy ''VideoGame/{{Odium}}''. Four times you have to kill the enemies before they kill a stationary NPC (who, of course, just stands there while enemies attack him). Once you have to protect some security monitors (why do the mindless monsters have an apparent temporary grudge against them is unexplained.)
* ''Zombie Horde 2''. Every once in a while you have to protect a box from zombie attacks.
* ''BattleCity'' series. Player has to protect the bird located in the bottom middle of the field from enemy tanks while staying alive as well.
* A (rather frustratingly difficult, at least compared to the rest of the game) battle towards the end of ''SakuraWars V: So Long, My Love'' has the party of [=PCs=] protecting various vital parts of an airship they're on.
* The classic arcade game ''MissileCommand''. "Defend Your Cities!"
* ''FinalFantasyVI'' has a few parts like this. Once near the start of the game where you have to protect an unconscious Terra from Imperial troops, and again with a similar mechanic later on when you protect a frozen Esper from more Imperial troops.
* ''MajorasMask'' requires you to protect milk jugs on the back of a wagon from Romani Ranch.
* The penultimate battle in ''VideoGame/GodOfWar'', where Kratos (you) has to protect the memory of his wife and child against hordes of evil versions of himself. ItMakesSenseInContext, really!
** In ''VideoGame/GodOfWar 2'', you have to protect a translator from a bunch of enemies so you can have him read some writing. Naturally, Kratos kills him immediately after.
*** Averted in ''VideoGame/GodOfWar 3'' though. Twice. First there's the [[spoiler: Possidon princess]]. You don't have to protect her; she just sits there while you fight enemies. Of course Kratos kills her soon after that. The next comes late in the game with [[spoiler: Pandora.]] You think you have to protect her from enemies but she does a good job of evading them while kill them. Meaning she never gets hurt by enemies, ever. However there are times where she falls into death traps you have to get her out of before she's killed though.
* ''MetroidPrime 3: Corruption'' has a mission on Elysia during which you have to kill all the Space Pirates and their ships before they destroy the Spire Pod, which is carrying the bomb that you need to destroy the shield protecting the Leviathan Seed. You're standing ''on'' the Spire while it's being attacked, by the way.
* ''WorldOfWarcraft'' has several of these. One where you have to protect a crystal from several waves of enemies, and another where you have to protect the Hourglass of Eternity, with some help from your future self. Later, you get to do it again, this time as the future self, helping your past self.
* In ''WolfQuest'', one of the missions is to protect your pups from the hungry coyotes and bears. It gets more difficult when you must [[EscortMission move them to the summer hunting grounds]] and an [[DeathFromAbove eagle]] decides they look tasty.
* The ''Franchise/MassEffect'' games have several:
** In the second game there's Archangel's recruitment mission. He's not immobile and he fights back against attackers, but without your help, he's toast.
** Same game, there's a short sidequest that involves you finding the badly injured sole survivor of a quarian ship crash, and protecting her from attacking varren until your shuttle shows up to pull you out of there. If she dies, you lose.
** There's also the sidequest you get fairly early on, which involves landing on a planet to retrieve twenty boxes of valuable cargo. Trouble is, once you arrive, a bunch of YMIR Mechs move in and start destroying said cargo. The relative success of the mission is determined by how many boxes you manage to keep from being destroyed.
** Variation in the Overlord DLC: the final boss consists of [[ItMakesSenseInContext shooting little holographic spheres sliding toward the VI core]]. If you don't kill them fast enough, then the rogue VI will upload itself to the Normandy, resulting in a NonStandardGameOver. Basically this has you protecting your own ship from a hacking attempt.
** In the third game, during the Tuchanka: Bomb mission, the final battle involves you preventing Cerberus forces from attacking Victus as he disarms the bomb.
* TowerDefense games are pretty much entirely focused on this idea.
* In ''{{Starcraft}}'', a few of the Zerg missions require you to protect a mysterious Chrysalis. Eventually it hatches, revealing [[spoiler:infested Kerrigan, who the Zerg had stolen in the penultimate mission of the Terran campaign]]. Only some of the missions technically count, as in the first few, it's small enough to be carried around by a Drone.
** In the sequel, you have to protect a laser drill while the Protoss send waves of troops against you. Fortunately, you get siege tanks in this mission, and you can aim the drill automatically, making short work of any enemy unit that's not in the fog of war.
** Ariel Hanson's missions involve you protecting a fleet of refugees from a variety of threats as they seek out a new homeworld. These threats range from infested zombie-like terrans to full-on zerg assaults to a purification squad helmed by Executor Selendis.
** [[spoiler:The final mission has you protect the Xel'naga artifact as it prepares to expunge the zerg influence from Char and deinfest Kerrigan. Naturally, she wants to wipe it out, and she will throw the kitchen sink at you to make certain you don't get to fire it off.]]
** ''{{Warcraft}}'' continues the long, glorious tradition. The final mission of ''Warcraft III'' is probably the most prominent: the object to be protected is ''the WorldTree''. Except you're not just protecting it -- you're protecting it while it gets rigged into a gigantic magical ''bomb'' meant for an archdemon. The mission is also fairly unique in that you get two allies with bases in front of the enemy's advance than you must try to aid to further protect the objective.
* Several missions in ''Naruto: Uzumaki Chronicles'' are like this.
* A [[ThatOneLevel particularly frustrating mission]] of ''[[{{VideoGame/Tribes}} Tribes: Vengeance]]'' is centered around Victoria protecting Daniel from onrushing Blood Eagles while he extracts the data from an enemy computer. The main problem is that the location is very poorly suited for prolonged defense, your resources are painfully limited, and there is no backup whatsoever (except a few automatic turrets).
* ''VideoGame/{{Bioshock 2}}'' has ADAM gathers, where the player must keep a crowd of splicers away from a Little Sister while she gathers ADAM from a corpse. While the splicers won't kill the sister if they get close, they will interrupt the gathering process.
* In both of the ''ModernWarfare'' games, there is a mission where the player has to defend a stationary objective. In the first one, the player's Marine squad has to protect a M1 Abrams tank that has been disabled. If the enemy get close enough, they'll use satchel charges to blow it up. In the second game, the player's squad has to defend a portable hard drive as it downloads the contents of a terrorist leader's computers while dozens of mercenaries rappel in by helicopter to try and destroy it.
* Occurs in ''VideoGame/GoldenEyeWii'' when you must protect Natalya from enemy gunfire while she tries to stop the Goldeneye satellite.
** Same with ''VideoGame/GoldenEye1997 64'', except it was much more frustrating.
* ''VideoGame/{{inFAMOUS}}'' has a particularly harrowing mission involving protecting a medical crate. If you've started down the [[KarmaMeter Evil path]], the waves of baddies can be subdued with a little [[ChainLightning mass damage]]... but if you have Good Cole's abilities... well, be ready to restart the mission a couple times until you manage to take out the gunner trucks and rocket launchers before they make your crate go kablooey.
* Protecting Hawk while he disarms a nuclear bomb in ''SoldierOfFortune''.
* A number of quests in ''VideoGame/DungeonsAndDragonsOnline'' are this, including two of the quests of Korthos Island.
* Several times in ''{{Conduit 2}}'', protagonist Michael Ford must protect the Free Drudge during the campaign.
* ''VideoGame/FableII'' has quite a few of these, one where you have to protect Garth whilst he activates a gate.
* ''VideoGame/ResidentEvil5'' has one of the BSAA members, Josh, inputing a code in order to turn on the power for the elevator for him, Chris and Sheva to escape on. You also have to do it again. He even [[LampshadeHanging remarks how much of a pain it is for you]].
** The second half of the Water Room in ''VideoGame/ResidentEvil4'', where you must protect Ashley from respawning Zealots with sniper cover while she hits a pair of switches to raise a bridge.
* The entire point of Sector Z in ''StarFox64'' is that the Great Fox [[TooDumbToLive just stops in the middle of nowhere]] while the enemy fires 6 large missiles in 1-2-3 sequences at it. Thankfully, you have plenty of time to destroy each missile, and they always come from the same direction. This mission is also paid homage to in Level 8 of ''Star Fox Assault'', when you have to protect the Orbital Gate from a lot more missiles coming from all different directions.
* Numerous examples from FireEmblem. Most frequently, it's an incapacitated "Ally" NPC, or some other figure such as [[RoyalsWhoActuallyDoSomething Royals who aren't as talented as yours at fighting]]. While many missions are "Seize the throne", there are a few where it's inverted which would also fit this trope. Some of them are also [[LuckBasedMission Luck Based Missions]], since if you are unlucky, the character you are supposed to protect can get killed before you even have a chance to reach him/her.
* In ''{{Solatorobo}}'', during Red's JourneyToTheCenterOfTheMind, the software begins by creating a warmup for him from his memories. He winds up defending Elh from a bunch of bugs, seeing as that's what he considered the most laughably easy thing to come up with. A later simulation reuses the "don't let the bugs near Elh" objective, but that one was [[spoiler:a RescueRomance situation [[ShipperOnDeck specifically set up by Merveille]].]]
* [[VideoGame/{{Turok}} "You must save the totem, Turok!"]]
* At the climax of JadeEmpire, Silk Fox and Dawn Star (you control one) are defending a bridge while Kang the Mad sets up explosives.
* ''VideoGame/TronTwoPointOh'' has several, mostly in terms of guarding the AI Ma3a who is carrying the algorithms needed to run the digitizing laser (Jet's ticket back to analog). One of them is sniping rival security Programs from a tower, another is fending off [[TheCorruptor Thorne]] and his horde of virus-inflected Programs in a BarBrawl.
* In ''VideoGame/BattlestarGalacticaOnline'', you can call in mining ships to handle resource-bearing planetoids. The payoff from these is greater than spending an equal amount of time doing normal {{Asteroid Min|ers}}ing. However, the game spawns mooks to go after the mining ships, as well as creating an indicator on the sector map that may attract enemy players. Of course, you can invert this by going out and hunting enemy mining ships.
* The second of the mid-game missions in ''VideoGame/MegaManZero 2'' contains a segment toward the end where Zero must protect Ciel as she disarms a bomb, which takes 90 seconds. The enemies coming after you two are quite weak, [[ZergRush but there are a lot of them]].
* ''[[VideoGame/{{Banjo-Kazooie}} Banjo-Tooie]]'' had a mission involving protecting a pig from incoming sharks.
* Protecting the American and Mexican presidents in ''GhostRecon: Advanced Warfighter''.
* There are a few of these in ''VideoGame/MiniRobotWars'' as "[[MiniGame Mission Stages]]"
* ''VideoGame/FalloutNewVegas'' has you fend off a Legion raid at Bitter Springs during Boone's companion quest, "I Forgot to Remember to Forget".
* ''VideoGame/AgeOfEmpiresII'' has a few in campaigns. In the El Cid one, one of your goals is actually to defend the ''body'' of El Cid because it was propped up on a horse to [[OfCorpseHesAlive convince people he was still alive]]. And yes, a dead body has hit points. Don't ask how. In almost any other scenario though, you're more likely to protect weaker cities or buildings.
* A number of missions in ''VideoGame/{{Borderlands 2}}'' are of this type. The last phase of one of Tiny Tina's missions requires protecting a generator from a stream of bandits; a mission in Opportunity requires protecting a hacked drone while it destroys Handsome Jack's statues; one of the Slab King's missions requires protecting generators hoisting Slab flags in hostile territory; a story mission requires protecting a beacon from waves of loaders.
* CallOfDutyGhosts has one in the "Clockwork" mission where you need to defend Hesh as he hacks the data center of the Federation base. You get a turret, several mines, claymores and tear gas, along with your teammates to help as the enemies try to flank you.
