->''"[[RuleOfThree EDF! EDF! EDF!]]"''
-->-- The EDF soldier's battlecry throughout the series

'''''Earth Defense Force''''' is a series of budget title ThirdPersonShooter games developed by Sandlot and published by [[Creator/D3Publisher D3 Publisher]].

Taking place in around the modern era, scientist have discovered radio wavelengths from outer space, thus proving the existence of extraterrestrial life. Unfortunately, these aliens aren't here to give humans an olive branch and welcome baskets, [[AlienInvasion they're here to take over the Earth]]. Not to sit idly by and let the aliens pave a path of destruction to take over Earth with swarms of [[AttackOfThe50FootWhatever giant]] [[BigCreepyCrawlies bugs]], [[KillerRobot robots]], [[EverythingsBetterWithDinosaurs dinosaurs]], and what else they decide to sic on Earth, the eponymous Earth Defense Force, unified multinational military force, was founded to stand up against the alien invaders.

One of the main draws of the series is how the game makes the player feel like they're in a Japanese {{Kaiju}} BMovie as they take on legions upon ''legions'' of enemies and the occasional Godzilla-sized monstrosities (including monsters that [[{{Expy}} looks]] [[CaptainErsatz like]] Franchise/{{Godzilla}}). The gameplay throughout the series is relatively simple: for the most part, you take control of an infantry soldier of the EDF to shoot down any-and-all aliens throughout many stages of the game. It's as simple as that. Along the way, you can find armor power-ups that increases your soldier's maximum health and weapon boxes to obtain new weapon; more powerful weapons are usually found by playing through the missions in harder difficulties.

The games in the series so far includes:
[[index]]
* ''Monster Attack'' / ''The Earth Defense Force'' (2004, [=PS2=]) -- Originally released in Japan in 2003 as Vol. 31 of D3 Publisher's Simple 2000 Series of budget title games for the [=PlayStation=] 2 and the first game in the ''Earth Defense Force'' series. It was never released in North America, but oddly enough, it was released in Europe in 2004 as "''Monster Attack''".
* ''Global Defence Force'' / ''The Earth Defense Force 2'' (2007, [=PS2=]) -- Released in Japan in 2005 as Vol. 81 of the Simple 2000 Series and a sequel to ''The Earth Defense Force''. The sequel expanded on the original with more missions, new enemies, and introduced the Pale Wings, female soldiers equipped with jet-packs with the ability to fly and reach higher ground. Like its predecessor, never got a North America release but it was released in Europe as "''Global Defence Force''" and "''Terra Defense Force''" in Korea. It later received an enhanced and Japan-only port in 2011 for the [=PlayStation=] Portable.
** ''Global Defence Force Tactics'' / ''The Earth Defense Force Tactics'' -- The oddball in the series. Released roughly around the same time as ''Global Defense Force'' but it was made from a different developer. The game was developed by [=thankArts=], and unlike the two previous games, this game was a tactical turn-based strategy game. The story took place after the events of ''The Earth Defense Force 2''.
* ''VideoGame/EarthDefenseForce2017'' / ''Earth Defense Forces 3'' (2007, 360) -- Released in 2006 in Japan, and while this is the third game in the series, it is first game to get a North American release. The game is more-or-less a remaking of the original ''Earth Defense Force'' since the game much like original. Like ''Earth Defense Force 2'', the game received an enhanced port on Sony's handheld system, this time being on the [=PlayStation=] Vita and brought back the Pale Wings from the previous game.
* ''VideoGame/EarthDefenseForceInsectArmageddon'' (2011, [=PS3=], 360, PC) -- More or less a follow-up to ''Earth Defense Force 2017'', however it was developed by Vicious Cycle Software instead and the first game developed outside of Japan. Unlike the previous games, ''Insect Armageddon'' lost some of the giant monster movie feel of the previous games but still keeps the spirit of the gameplay intact.
* ''VideoGame/EarthDefenseForce2025'' / ''Earth Defense Forces 4'' (2013, [=PS3=], 360) -- Expected to be released in July 2013 in Japan and sometime later overseas, it is the true sequel to ''Earth Defense Force 2017''. Taking place eight years after the events of ''Earth Defense Force 2017'', the Ravagers have returned in an attempt take over Earth again. Applying elements from the previous installments, ''Earth Defense Force 2025'' will feature four playable classes (Rangers, Wing Divers, Air Raiders, and Fencers) and online multiplayer.

----
!!We will defend the Earth from the alien invaders with the following tropes!
* ActionGirl: The Pale Wings (''Global Defence Force'' and ''EDF 2017'') and Wing Divers (''EDF 2025'').
* AllMythsAreTrue: Or rather "All Japanese Kaiju Movies Are True".
* AlienInvasion: What the Earth Defense Force is trying to prevent.
* AttackOfThe50FootWhatever: Giant bugs, robots, Godzilla-esque monsters, and then some.
* BadassArmy: The Earth Defense Force. They have fending off invading hoards of bugs for quite a while now.
* BeamSpam: Some of the enemies and bosses are capable of spaming laser beams all over the place.
* BeatThemAtTheirOwnGame: In some of the games, you may come across weapons made from using technology of the alien invaders.
* BeneathTheEarth: During the insect hive missions in some of the games.
* BottomlessMagazines: Subverted. Most of your weapons have infinite ammo, but just about every weapon have a limited clip size and have to reloaded once the clip runs out. There's no manual reloading whatsoever. Some weapons in the series cannot be reloaded at all unless you start a mission again.
* BugWar: With BigCreepyCrawlies no less.
* BulletHell: With bugs, robots, ships, and what else have you are spamming [[MoreDakka almost endless amounts of dakka]], you bet these games would have traces of this.
* {{Camp}}: A series of budget games where take control of a foot soldier fighting off waves of giant bugs, robots, flying saucers, and other kaiju-styled monsters.
* ChainmailBikini: More like "[[LeotardOfPower High-tech Leotard Armor]]" for the Wing Divers of the fourth game.
* DieChairDie: More like "Die, Buildings! Die!" since it's perfectly okay to shoot explosive weapons at random buildings and other inanimate objects with no consequences whatsoever.
* DidYouJustPunchOutCthulhu: [[spoiler:In ''EDF 2017'', Storm-1 destroyed the Ravagers' mothership -- a mothership armed to the teeth with ''hundreds'' of laser weaponry and a WaveMotionGun -- ''all by himself''!]]
* EasyModeMockery: [[ZigZaggingTrope Zig-zagged]]. You get the weaker weapons within Easy and better weapons on harder difficulties, but it's probably best to start on the easier difficulties to boost your health, as the hardest difficulties would be {{unwinnable}} without sufficient amount of health.
* EverythingBreaks: Just about everything in the outdoor areas can be laid to waste. Houses, skyscrapers, appartments, cars, trees, fences, you name it, and there's no penalty for riding them to get a better view of your enemies.
* ExcusePlot: [[VideoGame/BadDudes Aliens have decided to take over Earth. Are you a bad enough soldier to take on the alien invasion to save the world?]]
* FakeDifficulty: Any difficulty past HarderThanHard since the enemies can deal out insane amounts of damage to you and they have an absurd amount of health compared to yours, especially those God-forsaken spiders.
* FriendlyFireproof: A mixed example with these games; while your allies can't hurt you, you can hurt them. This is averted in co-op mode where players can accidentally (or intentionally) shoot each other.
* FlyingSaucer: Often a DropShip to unload more enemies for you to deal with.
* {{Giant Spider}}s: Oh yes, and they're often the most terrifying enemies in the game. And it is not just because they are damn ugly or [[InASingleBound can leap over tall buildings in a single bound]], but their silk can kill you quickly (especially on anything past Hard) if you're not careful or really unfortunate to run into them.
* HardModePerks: You get more powerful weapons on the harder difficulties, but suffice to say, you'll need some decent weapons and LOTS of health before attempting missions on the harder difficulties.
* HeroicMime: Your player character, aside from a few grunts and death cries.
* HeartContainer: The Armor pick-ups. Grabbing one will increase your maximum health by 1, but you won't get the health bonuses until after finishing the missions.
* HumongousMecha: The robotic enemies.
* HyperspaceArsenal: Subverted. You can amass ''hundreds'' of weapons at your disposal but you can only bring two at a time.
* IdiosyncraticDifficultyLevels: Often with the HarderThanHard difficulties.
** In ''EDF 2017'', we have Easy, Normal, Hard, Hardest, and [[FakeDifficulty Inferno]].
* InsectoidAliens: The bug enemies.
* [[InfinityPlusOneSword Infinity+1 Weapon]]: Often the bonus weapons you get after clearing the in the harder difficulties.
** [[spoiler:''EDF 2017'' gives us the Genocide Gun, a WaveMotionGun that deals [[ThereIsNoKillLikeOverkill 1,000,000]] damage! The downside is that the blast could kill you (and your allies) too and certain non-mook enemies are immune to it and you have unlock it by beating all 53 missions on Inferno.]]
* JetPack: Often the female soldiers in the games use them to reach places the standard infantry soldiers can't.
* {{Kaiju}}: The non-robotic and non-insect enemies.
** In the first two games, we have the [[CaptainErsatz Saurus]], giant dinosaur-like monsters that breathes fire.
** In ''EDF 2017'', we have Vallak, which are much like the Saurus from the previous games but they also have cyborg version of the Vallak armed with plasma cannons on their shoulders.
* KillerRobot: The robotic enemies that the alien invaders often throw into the mix.
* LifeMeter
* MacrossMissileMassacre: Some of the missile launchers in the series can shoot several missiles at once. Certain enemies can fire multiple missiles too.
* {{Mooks}}: The black ants and the fighter ships.
** AirborneMook: The fighter ships and hornets.
** EliteMooks: The red ants, some of the spiders, and the "Elite" fighter ships.
** GiantMook: The queen ants and giant spiders.
** MechaMooks: The robotic enemies.
** MookMobile: The fighter ships.
** SmashMook: The red ants will ram into you unlike the black ants that sprays acid at you.
* MookMaker: Often in the form of {{Drop Ship}}s or a mounds on the ground where the alien bugs have made their breeding grounds.
* MiniMecha: In some of the mission in these games lets you pilot one. ''EDF 2017'' and ''EDF 2025'' have the Battle Machine Velgata, the latter has two variants of these mini-mechs.
* NewGamePlus: Of sorts. After beating all the missions, you can replay them again with all of your weapons and maximum health intact, which might help when it comes to tackling the game's harder difficulties to obtain some of the more powerful weapons.
* NotTheFallThatKillsYou: One of the AcceptableBreaksFromReality the series happens to invoke.
* OneManArmy:
** Often the case with these games. Despite getting assistance from the other troops from time-to-time, Storm-1 pretty much single-handedly took down the Ravagers [[spoiler:the their mothership]] from ''EDF 2017''.
** You take on enormous legions of enemies!
* PainfullySlowProjectile: Some of the projectiles in the series travel incredibly slow. Inverted with some weapons though as some travel ridiculously fast.
* PantyShot: Can be possible for the Pale Wings in the second and third games as they fly.
* PreAsskickingOneLiner: Some of your allies are prune to saying one in the midst of battle. From ''EDF 2017'', "Do you like death?! Then die!"
* RobotWar: Usually during missions when you're fighting off giant killer robots instead.
* SceneryGorn: Often the result of the alien invaders (or you) as the Earth Defense Force fend of the invasion.
* TheSwarm: In some of the games, not only do you fight off swarms of giant ants and spiders, you also fight off swarms of [[EverythingsWorseWithBees hornets and bees]]!
* TwentyMinutesIntoTheFuture: The series started in 2004 (2003 in Japan) and the story of the games so far took place between 2013 (''Monster Attack'') to 2025 (''EDF 2025'').
* ZergRush: The red ants favorite method of attack.
* ZettaiRyouiki: The Pale Wings in the second and third games are wearing ThighHighBoots.
