''Earth Defense Force 2025'' (known as ''Earth Defense Forces 4'' in Japan) is a ThirdPersonShooter developed by Sandlot and published by D3 Publisher. The game is a direct sequel to 2007's ''VideoGame/EarthDefenseForce2017'', taking up the story [[TwentyMinutesIntotheFuture 8 years later]].

The Ravagers have sprung up from underground [[AlienInvasion to invade Earth]] once again and it's up to the Earth Defense Force to stop them. If you're familiar with the previous games in the series, you should know what to expect: players will take control of a foot soldier and gun down any-and-all Franchise/{{Godzilla}}[=-=][[AttackOfThe50FootWhatever sized]] [[BigCreepyCrawlies bugs]], [[HumongousMecha robots]], and other monstrosities the Ravagers sics at Japan (and you).

Unlike Vicious Cycle's ''[[VideoGame/EarthDefenseForceInsectArmageddon Insect Armageddon]]'', this installment retains the BMovie charm and sense of scale the series is known for. Taking cues from all three of its predecessors (most notably ''Earth Defense Force 2''), the game features four playable classes this time around. Rangers, the standard infantry unit; Wing Divers, female soldiers equipped with jet packs to fly; Air Raiders, support soldiers that can call in air strikes, vehicles, and other support items; and Fencers, walking {{Powered Armor}}ed men with long-range artillery, a sledgehammer, pile bunker, and dual-wieldable chainguns. Enemy variety has also been stepped up along with the addition of online multiplayer for up to four players, allowing you and your three other EDF team-mates take on the Ravager horde together.

The game was released on July 4, 2013 in Japan, February 18, 2014 in North Amercia, and February 21 in Europe for [=PlayStation=] 3 and Xbox 360. The game had several pre-order bonuses, depending on where you pre-ordered the game, but has become available for free. One of them in Japan was a crossover with ''VideoGame/DreamCClub'' where Mian and Setsu are featured in ''2025'' as balloon decoys for your Ranger and Air Raider respectively to use in combat if purchased directly from [=D3=] Publisher. ''Dream C Club: [=GoGo=]'' also featured the Pale Wing's uniform from the Japan-exclusive ''Earth Defense Force 2''. [=GameStop=] pre-orders offers the Air Raiders Weapons Pack, which includes a gold-coated model of the [=BMO3=] Vegalta with a combat burner to throw flames and take flight for short periods of time when equipped plus Pure Decoy Launcher (Setsu). Amazon pre-orders offers the Ranger Weapons Pack, which includes Volatile Napalm Discharge Device and the Pure Decoy Launcher (Mian).

An UpdatedRerelease titled ''Earth Defence Force 4.1: The Shadow of New Despair'' was released for UsefulNotes/PlayStation4 in December 2015, which was also released on UsefulNotes/{{Steam}} in July 2016.

----
!!The EDF will show the Ravagers what we've got with these tropes:
* AccidentalAimingSkills: It's not uncommon for a player to miss their intended target and hit something equally important or dangerous anyway.
* ActionGirl: The Wing Divers, an all-female division of jetpack-wearing badasses.
* AlienInvasion: The Ravagers have returned again to attack the Earth.
* AliensAreBastards: The Ravagers again are attacking the Earth trying to exterminated humanity without rhyme or reason. Again they unleash hordes of giant mutant monsters of all shapes and sizes to try and wipe out humanity.
* ArtificialStupidity:
** AI Wing Divers like to repeatedly jet up in the same location to the point of ''running out of energy.''
** Your fellow EDF soldiers also have a distressing habit of walking or flying in front of you just as you fire off a powerful weapon with a dangerous area of effect. This has predictably infuriating results.
** In enclosed areas like tunnel missions, EDF troops will call out nearby bugs, and proceed to open fire... into a wall, because while they are close by, they're still not visible yet.
* AttackOfThe50FootWhatever: In addition to the normal giant insects, there are a few especially large species such as the King Spiders that dwarf buildings.
* AttackAttackAttack: Beyond use of specialized units in certain scenarios, this is the general plan for both the EDF and the Ravagers. Both sides will just keep attacking until the other is effectively wiped out.
* AutoSave: A first for the main series.
* BadassArmy:
** The E.D.F. does not mess around with their fighting, despite their being caught unawares by the invasion. The NPC soldiers become tougher and deadlier the higher up in difficulty one goes. It goes to the point where one of the better strategies for farming new equipment is to run away from the fight, and come back to pick all the boxes when the E.D.F. troopers have killed most of the bugs/Ravagers.
** Applies to the EDF in story as well as gameplay. The Ravagers return with multiple motherships. In 2017,just one of these ships was nearly unstoppable. Out of the 10 that are on their way to earth, about half are destroyed by planetary defence weapons before they even arrive. Most of the ones that do make it are destroyed about half way through the game by both the player character, and other squads in offscreen battles.
** This is inverted on lower difficulties, where E.D.F. soldiers will be messily slaughtered by small groups of insects. It only gets worse when the giant robots show up.
* BattleCry: Chanted by the EDF troops and a faux news reporter in a viral ad for the game. Specifically "EDF!, EDF!, EDF!"
* BeamSpam:
** Several enemy types have energy weapons that fire several shots or are "Laser Machine Guns".
** Some of the Wing Diver's weapons give the player the ability to spray energy weapon fire at their enemies, most notably the short-range Rapier that practically makes the user a ''walking laser rave party.''
* BeeAfraid: You'll be going up against giant hornets this time around. Hornets that resemble the [[http://en.wikipedia.org/wiki/Asian_giant_hornet Asian giant hornet]].
* BeeHiveBarrier: The Ravagers Shield Bearer mechs DeflectorShield is a beehive barrier.
* {{BFG}}: The game is chock full of BFG's wielded by the players and allies alike. The Hectors/Walking Arms of course still wield their various BFG guns including the big artillery arms.
* {{BFS}}: The Fencer can wield very large sword weapons of various types.
* BigCreepyCrawlies: The many bug enemies such as varieties of ants, wasps, and spiders. The mission pack DLC adds mutant and metallic varities of these enemies as well.
* BloodierAndGorier: [[http://www.youtube.com/watch?feature=player_embedded&v=GRyM8BZv8Co One of the trailers]] shows a Ranger getting picked up by an ant from the jaws and being throw like a rag-doll with blood gushing from his body. The same trailer showed a Ranger blowing up an ant into pieces with a rocket launcher while trying to fight off the horde of ants. The gratuitous sprays of organic enemies' blood is back with a vengeance. The exaggerated gouts of blood appear every time a biological enemy is injured or destroyed.
* BlownAcrossTheRoom:
** When an enemy is killed by a powerful weapon the bodies tend to flung away with a fair bit of force.
** Some attacks such as the plasma artillery from the Hectors, can send players flying when hit.
* BoringButPractical: The Ranger and most of his weapons. There's really nothing particularly exotic about the Ranger - he can't fly, he doesn't call down artillery strikes or summon tanks and mechs, nor does he dual-wield huge guns and melee weapons. He's in the middle in most attributes, but he's the best for raining hell on the battlefield with his extremely practical weapons and getting in the driver's seat of any extra vehicles the Air Raider calls in.
** Some of the Air Raider's items fall into this category too. Letting allies lock on faster with missiles and buffing their defense or damage isn't very interesting, but it can make a huge difference in a close fight, especially because the latter applies to all friendly AI in range too.
* BribingYourWayToVictory: While not a straight example, the DLC missions allow you to get high level weapons very early on and can also be used as an early game means of farming for armor.
* BugWar: A large number of your enemies are giant bugs of various types.
* ChainsawGood: One of the more interesting Wing Diver weapons is the Laser Chainsaw, which fires a chainsaw-shaped torrent of energy in a narrow cone. It will eviscerate any bug up to medium range.
* ChainmailBikini: Lamp-shaded by the Wing Divers' own conversation. Sometimes they'll complain about not wearing armour suits even though it makes them light. That said, the amount of armor they do wear isn't gratuitous by the standards of this trope. They wear more of a metallic one-piece swimsuit.
* ChargeAttack: Fencer swords and hammers have can have multiple modes depending on their level of charge, sometimes acting like completely different weapons at different levels.
* CombatMedic: The Ranger and Air Raider both have healing weapons in the form of Reversers for the former and Life Spots for the latter.
* TheComputerIsACheatingBastard: In your favor. NPC troopers armed with the AwesomeButImpractical, reverse-engineer Ravager tech don't have the same ammo limitations as the player, letting them provide BeamSpam cover fire.
* ContinuityNod: One of the EDF soldiers late in the game will talk to his fellow trooper about a [[VideoGame/EarthDefenseForce2017 "legendary soldier from the Storm Trooper squad"]], who turned the tide of a Ravager invasion all by himself. The other soldier dismisses it as a myth, though. Some dialogue has rumor spread that they're now a member of [[PlayerCharacter Storm Team]].
* CoolBike: There is a two person motorcycle vehicle that has a sidecar with a machine gun. Yes, you can drive a machine gun armed motorcycle to fight hordes of giant bugs, 50 foot tall killer robots, and any other enemy they throw at you.
* CoOpMultiplayer: Present in this installment like its predecessors, in local split-screen co-op and, like ''Insect Armageddon'', online multi-player.
* {{Crossover}}: Between this game and ''Dream C Club''. In ''EDF 2025'', the Ranger and Air Raider can use the Pure Decoy Launcher to create balloon decoys of Setsu and Mian respectively. Likewise, ''Dream C Club: [=GoGo=]'' featured the Pale Wing's uniform from ''Earth Defense Force 2'' for the girls to wear.
* DeathFromAbove:
** Several enemies attack the player from above, notably the various gun ship enemies. The various bugs will climb buildings and attack or shoot the player as well.
** Several weapons have projectiles fly up high, then dive down on the target below them.
** One of the weapon types of the Air Raider is to call in various air/support strikes, often raining fire from above the battlefield.
** Some of the HumongousMecha enemies get in on the act and use the height advantage to fire down on the player, and the Hector's long range plasma artillery can still swat the player from clear across the map.
** Player summoned and driven missile artillery vehicles which fires multiple homing missiles which usually need to be fired at a high angle causing the missiles to turn around at a high point and seek out the targets below.
* DeflectorShield:
** A new type of enemy HumongousMecha creates a shield bubble forcing players to walk inside to destroy any targets and the generator.
** Some of the enemies' Hectors now have a hand mounted energy shield to help protect them against the player's fire.
** Enemies that have a shimmer effect on their surfaces are shielded and take more damage to kill.
* {{Determinator}}:
** You better believe the EDF is a whole army of them. They refuse to back down in the face of overwhelming numbers, superior technology, and will not surrender since the Ravagers want every human dead.
** Near the end of the campaign, the EDF is basically defeated. Their HQ has been found and destroyed multiple times, most of the planet is trapped beneath World Eaters, and they've already issued instructions to the civilian populace to begin a guerrilla fight against the Ravagers. The player's squad, which has been fighting through increasingly insurmountable odds as the game progresses, is part of the EDF's final, desperate assault on the 'Brain' controlling the invasion. As the attack fails and the last hope of the planet fades, the squad's status as a group of Determinators is revealed and immediately [[LampshadeHanging lampshaded]]:
-->'''Tactics:''' Attack units almost destroyed.
-->'''HQ:''' We couldn't match their strength...
--> '''Tactics:''' No, not yet. Someone is still fighting. It's the Storm Team!
-->'''HQ:''' Are they immortal or something?
* DevelopersForesight: The communication menu in multiplayer has a message for practically every situation that can occur in-game. There are a huge amount of gestures that most players wouldn't have time to access during a fight, with an added bonus of Air Raiders' backpacks actually responding to what their operator is doing.
* DestructiveSaviour: There is no penalty for demolishing buildings in the battlegrounds. A long mission in a city will usually see that place a flattened pile of rubble. The [=E.D.F.=] is defending the Earth, not the property of Earth!
* DieChairDie: Just like in the previous games. You can wreck random buildings with no consequences whatsoever.
* DifficultButAwesome:
** The very existence of the DLC missions is this trope; the enemies are tougher and more dangerous, but they also net more items per mission play through.
** The Fencer class exemplifies this trope. It requires learning how to deal with its slow attack speed on most weapons, setting up both DualWielding loadouts to maximize mobility due to the jump and dash effectively being SecondaryFire on the weapons and guns damping the turn rate compared to melee weapons, and most importantly, knowing how to LagCancel the side dash. But once mastered, the Fencer becomes a LightningBruiser that can outrun most vehicles, dance around enemies' attacks while hitting hard, and soften up enemies from a distance with heavy artillery fire once in position.
* DropTheHammer: The Fencer's vibro hammers, which can either launch shockwaves several hundred meters or cause massive explosions.
* DualWielding: Fencers can carry four weapons at a time and wield two at once, one in each hand.
* EliteMook:
** Red Gunships are just tougher palette swapped gunships that have more health, fire higher number and more powerful shots, and fly faster.
** The Giant Red Ants are basically the black ants from the first level but with more health, more speed, no ranged attack, and amore powerful bite attack.
** PaletteSwap and simply making some enemies larger with more health, damage, and speed is common through out the game. This includes two different varities of smaller dragons by colour but also giant "mutant enemy wasps that are larger red versions that have been beefed up in speed, attack, and health.
** The various enemies in "Time of the Mutants" DLC has several stronger palette swapped enemies. Examples include Silver Spiders, Gold Ants, Green Ants, Purple Retarius, and other coloured enemy variants. Mutant enemies encountered in the main game also appear as do palette swapped KingMook examples.
* EarthIsABattlefield: The Ravagers are attacking the entire planet. The EDF fights them at number of global locations.
* EnergyBow: A sci-fi variation on the energy bow. The Pale Wing character uses weapons that appear to be high tech crossbows and bows that shoot some sort of energy projectile.
* EnhancedArchaicWeapon: The sword, shield, and war hammer weapons of the fencer. They are basically medieval weapons designs given a sci-fi twist to fit the game.
* EveryBulletIsATracer: Pretty much every shot you fire will be a tracer to help the player track the projectiles path.
* EverythingBreaks: Many of the structures in a city-scape can be blasted into rubble. See also DieChairDie.
* ExcusePlot: The Ravagers are invading! Go join the Earth Defense Force and fight them off! Who needs immaculate plotlines and [[LargeHam cholesterol-free]] voice acting when you can just blow thousands of giant bugs into purple goo?
* FireBreathingWeapon:
** Flamethrower weapons making KillItWithFire possible for both the mechs and players via flame thrower type weapons.
** Dragon enemy types will fly around spewing fire onto the player and NPC allies.
* FlashStep: Melee weapons for the Fencer also come with side dash functionality that effectively turns the MightyGlacier into a LightningBruiser once you realize you can LagCancel it with a shield deflector.
* FlechetteStorm: Some of the limpet bomb guns charges send out a shower of flechettes that often ricochet at least once when detonated.
* FlyingSaucer: The air foil saucer drop ships make a return and this time they are accompanied by plate like ships that can lock together to form a larger ship.
* FrickinLaserBeams: Just like in most scifi b-movies expect all the of the energy weapons to follow this trope to varying degrees including laser pulses.
* GameplayAndStorySegregation: Somewhat justified since there are battles the player isn't participating in, but it can sometimes be really jarring to hear dialogue bemoaning the seemingly hopeless war or your team mates cowering in fear while you effortlessly tear through wave after wave of aliens singlehandedly.
* GatlingGood:
** Gatling guns make a return on the mechs.
** The Fencer Character can DualWield Gatling gun weapons.
* GiantSpider: The jumping wolf spider like aliens and their large "King" variant make a return. This game also introduces a new giant spider that weaves webs on buildings that resembles a Golden Orb Weaver. All the spiders shoot out web to attack the player.
* GrenadeLauncher: A sort of mid-range explosive weapon with some firing exotic projectiles. Often fired with a ballistic arc.
* GuiltFreeExterminationWar: The players are trying to help completely wipe out the Ravagers on earth. It helps that the creatures are all either giant bugs, drones, or giant robots. Further adding to it is the Ravagers always initiate the war with an apparent goal of completely wiping out humanity turning this into a kill or be killed conflict.
* GunsAkimbo: The specialty of the Fencer who can wield two of any of his gun weapons.
* HighlyConspicuousUniform: Played with. Thanks to the players ability to change the colour scheme of the classes this can range from being relatively low key to extremely obvious.
* {{Hitscan}}: Some of the weapons in the game especially high velocity or laser beam weapons are hit scan weapons. Averted for almost everything else, it's notable with the assault rifles of the Ranger that some of them have the advantage of especially fast-moving bullets as part of descriptions. Plasma weapons such as the Ranger's Plasma Bombers and the Wing Diver's plasma weapons are especially sluggish to the point where a Wing Diver can accidentally fly into her own shot.
* HomingLasers: One of the Wing Diver’s classes of weapons is a set of homing weapons which are specifically lasers.
* HomingProjectile: There are several varieties present in the game from missiles to homing lasers.
* HordeOfAlienLocusts: The believed behavior of the aliens and their chief motive for the invasions.
* HumongousMecha:
** The Hectors, otherwise known as "Walking Arms".
** The Aliens Giant Walking Fortress makes a return.
** BMX 10. Large player pilotable mech that almost resembles something out of Warhammer 40k armed with rail guns and missile launchers.
** The Aliens Tripod mecha, Deroy, looks like it was ripped right out from The War of the Worlds.
** The Shield Bearer, a walking deflector shield that is 'gigantic.'
** The Argo, a flying battleship that transforms into 300 meter tall mecha.
** In EDF 4.1 the Air Raider can summon the massive Walking Fortress Balam.
* HyperSpaceArsenal: Players carry multiple weapons that often would be at best difficult to carry stored. Multiple missile launchers, large energy weapons, Gatling guns, cannons etc.
* ImpossibleItemDrop: The enemies drop armor upgrades, health, and weapon boxes. None of the enemies should be carrying EDF-specific gear! This is the most obvious with the drops from the biological enemies.
* InfiniteSupplies:
** Played straight with the majority of the players weapons and equipment. The player has an infinite supply of ammo, but they do need to reload.
** Averted with certain weapons which can't be reloaded because the required equipment is too cumbersome to carry, as well as all vehicles.
** This is also PlayedForDrama with the Ravagers, who can teleport transport ships directly to Earth and have weapons that can [[spoiler:cover the entire planet.]]
* ItemFarming: Enforced. It doesn't matter how good of an [=E.D.F.=] soldier you are, you will need to spend time grinding out armor and better weapons in order to not die instantly on later missions.
* ItsUpToYou: Most of the time, the battle will be decided by you, though your allies can win some battles entirely without you.
* JavelinThrower: Using his Javelin Catapult series, the Fencer can impale foes with an indirect-fire barrage of special alloy spears.
* JetPack:
** The Wing Divers use them to [[{{Flight}} fly]].
** Some of the Giant Mechs the players can pilot appear to have jump jets and jet packs mounted on them.
* Jiggle Physics: Although it can be tricky to see with the camera, Wing Divers do have this.
* {{Kaiju}}:
** Some of the giant monsters resemble Kaiju. Specifically giant bugs, giant robots, and even dragons.
** 4.1 added the Erginus, a Godzilla knockoff and reference to the giant lizards in past EDF games.
* KingMook: Several of the insects have KingMook variants that are just larger and more powerful palette swapped versions of enemies. A couple other enemies also have KingMook variants including Erginus[[note]]Godzilla like monster[[/note]] and the dragon enemy boss.
* KillItWithFire:
** The tagline for the [=PS4=] port ''Earth Defense Force 4.1'' is "KILL IT WITH FIRE."
** The Fireghost variant of the [[HumongousMecha BM03 Vegalta]] packs [[GunsAkimbo dual flamethrowers]] and [[ShotgunsAreJustBetter dual shotguns]] to demolish anything that gets close. It makes short work of Hectors even on [[HarderThanHard Inferno]] difficulty!
** There is a line of flame thrower weapons for the Ranger.
** Meanwhile, the Fencer doesn't get mere flamethrowers, but [[RevolversAreJustBetter Flame Revolvers!]]
** The ranger has access to incendiary grenade launchers which fire incendiary shells.
** One of the DLC weapons for the Fencer is a RecursiveAmmo fire bomb missile which lays trail of burning pillars when it is fired.
* KillSat: Air Raiders can come across an air strike called Spritefall, which is a laser satellite up in orbit. Activating it tends to scare the mission control operator.
* KineticWeaponsAreJustBetter: Many of the guns and other weapons in the game are kinetic projectile based weapons. The Ranger class uses a large number of kinetic weapons as does the Fencer. Even the Air Raider either uses kinetic based weaponry or their various bits of gear utilize it in some way. The only exception is the Wing Diver who specializes in energy weapons.
* LagCancel: Essential for mastering the Fencer's [[FlashStep side dash]], and generally done by using the shield deflector right after the dash ends.
* LandMineGoesClick: The various mines you can deploy tend to go click a split second before they go off.
* LeadTheTarget: Some of the weapons require a little lead time due to projectile flight times and/or ballistic trajectories.
* LethalJokeItem:
** The Ranger's Acid Gun is little more than a Super Soaker that shoots acid at short range, but that aside it's one of the best early-game short-range weapons in terms of damage output, ammo capacity and rate of fire.
** The Ion Mirror Shield seems highly impractical as a shield due to its low integrity and general impracticality of spamming the deflector to avoid damage - until you realize that spamming the deflector is how you LagCancel the Fencer's dash, the Ion Mirror Shield has the lowest energy use for the deflector, and the level 0 version has a short reload time once you run out of energy from rampant deflector use. Simply put, it's the item that most reliably enables the Fencer to be a LightningBruiser.
* LeotardOfPower: The Wing Divers' uniforms are more {{Stripperiffic}} than the Pale Wings' uniform from ''Earth Defense Force 2017''[='=]s PS Vita re-release.
* LightningGun: Some of the Wing Diver weapons fire a powerful burst of lightning.
* LivingWeapon: The various organic enemies are all living weapons. These are the most common enemy type encountered in all their varieties.
* LuckilyMyShieldWillProtectMe:
** The Fencer can use a variety of shields to protect themselves from damage from the enemies, or even deflect projectiles back at the sender.
** Some Hector variants have a portable "energy shield" - see DeflectorShield above.
* MacrossMissileMassacre:
** Some of the players' weapons function like this by locking onto multiple enemies and spamming multiple missiles.
** A Player pilotable Missile Artillery tank that spams missiles.
*** An advanced variant that fires RecursiveAmmo missiles that split into further smaller missiles before impacting the target.
** One of the Mini-Mech vehicle types has shoulder mounted mini missile pods that look like something right out of an anime like Macross.
* MightyGlacier:
** The Fencer hits hard, is the only class capable of DualWielding, can carry a shield that can reduce damage taken and even deflect attacks, and his armor level develops the fastest out of all the classes. However, he's slow to turn when using guns, has poor acceleration when trying to run (plus he always has to restart his run whenever he attacks or stops moving), some of his guns have terrible recoil that paralyzes him for a second or two after firing, and using a shield reduces his movement to a crawl.
** This can be subverted by equipping weapons that give him [[FlashStep side thrusters]], like most melee weapons. The cooldown on the dash can even be [[LagCancel cancelled]] by activating the shield deflector right after the dash ends, turning the Fencer into an outright LightningBruiser that can cross the map at high speed, consistently evade enemy attacks and one-shot most enemies with a good melee weapon. On top of that, melee weapons don't slow down the Fencer's turn rate at all, so you can switch to melee to prevent those pesky Ravagers from attempting to flank you.
* MiniMecha: While pushing the boundry of mini mech, the game has an assorted variety of mini-mech variants with various weapons mounted on them. They can be armed with flame throwers, large bore BFG like shotgun cannons, missile pods, howitzers, Gatling Guns, and other weapons.
* MissileLockOn:
** The players weapons get a bounding box and cross hair with a beeping sound indicating it is tracking an enemy. The icon will flash and emit a sound letting the player know they can fire the weapon.
** Subverted with some of the Fencers missiles which instead require the target to be designated by an Air Raider equipment with a designator weapon.
* MissingBackBlast:
** None of the rocket launcher weapons have any form of back blast when launched.
** Subverted for the missile launchers. The missile launchers use a realistic soft launch[[note]]A small charge kicks the missile out of the launch tube where the main motor kicks off and launches the missile at full speed[[/note]] which mitigate or eliminate backblast.
* {{Mook}}:
** The game is full of Mooks of varying types. The most bog standard being the Black Ant enemy type. This is the very first enemy type that you will fight in the game.
** AirborneMook: The silver flying gunships serve as massed disposable enemy mooks and are the first flying mook the player encounter.
** MechaMook: The bog standard Walking Arms aka Hectors serve as common giant robotic mooks.
* MoreDakka: Although Rangers can achieve some impressive sprays of bullets with just an assault rifle, the Air Raiders up the ante with vehicle-mounted machineguns while the Fencers can [[DualWielding dual-wield]] ''handheld miniguns.''
** Features heavily in the Wing Diver's arsenal. The rate of fire on many of her weapons is 60 shots per second - the Fencer can only achieve this level of bullet spew by duel-wielding the lightest versions of his gatling guns, while the Ranger only gets it for his non-recharging laser rifles.
* MookMaker:
** The Walking Fortress spawns several varities of enemies for the player to fight.
** Both types of drop ships operate like this spawning enemies from their undersides in large numbers.
** The giant wasp hive until destroyed constantly spawns wasps.
** The various "Bug Holes" you will encounter can spawn enemies in large numbers.
** Part of the "Earth Eater" ship is enemy spawner panels that spit out several enemy types.
** "The Mother Ships" will spawn multiple enemy gunships when they are around to attack the player.
* MultiMeleeMaster: The Fencer can carry any DualWielding combination of axes, swords, spears, warhammers or shields at the same time. This is mostly viable only if the Fencer has overpowered weapons and armor or is playing on a lower level of difficulty where ants are the only enemy.
* NoScope: None of the zoom capable weapons require the player to use the zoom to shoot enemies. The weapons accuracy remains the same in zoomed in or out making them useful at pointblank range as well as long range.
* NoRangeLikePointBlankRange:
** Anything with a "D" or worse in accuracy will pretty much require this, though damage doesn't actually drop with distance until the bullets [[ArbitraryMaximumRange cease to exist]].
** Some of the more agile enemies are hard to hit unless you are firing on them at point blank range.
** Many enemies will rush up to the player at point blank and blast them with concentrated weapons fire. Even the bombardment Hector Robots will fire off point blank plasma shots into players.
* NotTheFallThatKillsYou: You will never take any damage from falling, regardless of height.
* OurDragonsAreDifferent: There are flying dragon like monsters that breathe fire and grab the player in their mouth and maul them. [[spoiler:They also apparently evolved from the giant insects.]]
* OneHitKill: Sniper rifles and the Fencer's handheld cannons and [[PileBunker Blasthole Spear]] will usually do this to most enemies. Additionally, the Mothership's [[NamesToRunAwayFromReallyFast Genocide Gun]] will instantly kill you if you're caught in the blast.
* OneHitPolyKill: Several weapons available to players fire shots that are capable of penetrating through any enemies in their path, no matter how many there are.
* OnrushingArmy: The most common tactic of the enemy bug hordes is to just rush forward in one large noisy mass.
* OurWeaponsWillBeBoxyintheFuture: A common aesthetic with the various advanced or sci-fi weapons.
* PainfullySlowProjectile: Some of the assorted projectiles have a fairly slow travel speed like the Air Tortoise. They can take a sometimes dangerously long time to reach their target, but you will know when they land.
* PileBunker: The CC Piercer spear line of melee weapons for the Fencer. It pierces the target and explodes! Comes in several varieties:
** The Blasthole Spear. Low fire rate, but high damage and surprisingly high range, both of which increase on followup second shots.
** The Flashing Spear, which trades off raw single-shot damage for rapid-fire capability. There's still an initial delay before it fires, however.
** The Blast Twin Spear, which is effectively a ''double'' Blasthole Spear!
* PlasmaCannon:
** The Ravagers' Walking Fortress, Hectors, and a few other enemies utilize some form of plasma cannon, often lobbing the shots from long distances as a form of artillery.
** Wing Divers get access to a whole line of plasma cannon-like weapons as part of one of their weapon classes. Including an example that strongly resembles the Ravager plasma artillery projectile.
* PoweredArmor: The Fencer class, as well as the RedShirt versions. It's an up-close-and-personal unit with katanas, mechanical war hammers, [[GatlingGood Electric Gatling Guns]], and various [[{{BFG}} shoulder-mounted artillery.]]
* PowerFist: The Fencer's Jackhammer mixes this trope with the PileBunker, being a armored gauntlet that can rapidly punch a target.
* {{Samurai}}: From [[http://www.youtube.com/watch?v=Rgj2RsawbIc the game's third trailer]], the Fencers are "[[EverythingsBetterWithSamurai the Samurai]] of the 21st century". They also bear some resemblance to European knights with the use of the large shields. The Fencer also has themes of medieval knights mixed alongside the strong samurai theme.
* RagdollPhysics:
** Some of the enemies go limp and just fall over like a rag doll. Notable in the original Hector arms enemies.
** Players tossed into the air by explosions, enemies grabbing and throwing them, or otherwise forcefully propelled go rag doll in the air until they land on the ground.
* RandomlyDrops: Has returned with a vengeance after Insect Armageddon's level up system. All weapons are randomly found in crates dropped by enemies along with armor upgrades and health kits.
* RareRandomDrop: Although technically all weapons have an equal chance of dropping, on higher difficulty levels the range can go from 50 levels or more, meaning you will see a lot of repeats of low quality trash before getting that coveted level 90.
* RayGun:
** This general weapon type is the forte of the Wing Diver class. They will utilize any number of energy weapons throughout the game.
** Several of the Ravagers weapons are a form of ray gun or another.
** Both the Fencer and Ranger get ray gun type weapons.
* RealTimeWeaponChange: Weapons are swapped in real time without use of a menu via one of the buttons on the controller.
* RecursiveAmmo:
** One of the Naegling Self-Propelled Rocket Tanks has a variant that fires missiles that split into a swarm of smaller missiles.
** One of the Fencers missile variants fires missiles that shower an area with bomblets.
** There are a few variants of Fencer Artillery that eject explosive bombs along its flight path.
* RedshirtArmy: Although sometimes the NPC soldiers can hold their own, nobody seems to care if they get slaughtered en masse by the insects or a particularly trigger-happy player.
* RevolversAreJustBetter:
** The EDF are particularly fond of Revolver Cannons on their mechs, a real-life loading method for large-bore weapons that moves shots from the magazine into a multi-shot cylinder.
** The Fencer gets the [[KillItWithFire Flame Revolver]], a ''flamethrower revolver'' that happens to be one of the most devastating close-range weapons you can use - if you can manage the recoil.
* RuleOfCool: Aside from the B-movie charm, the game revels in a sense of unbridled cool. Players use a wide variety of unique weaponry to flatten giant bugs, robots, alien vehicles, etc.
* SceneryGorn: Between the various giant robots and players using explosive weapons, the cityscape frequently gets flattened. The buildings and other structures often fall in a variety of satisfying ways, only leaving behind rubble piles. The destruction is not strictly limited to buildings.
* SecondaryFire:
** A variety of weapons and equipment require or make use of a secondary fire for their full range of capabilities.
** Placeable weapons like turrets and bombs need to be activated.
** Sniper weapons have a scope function.
** Some of the Air Raiders weapons shoot remotely detonatable {{StickyBomb}}s.
* SentryGun: Just like in the last game there are deployable sentry gun turrets that will track and fire on various enemies when they are activated.
* SequenceBreaking: There's nothing stopping you from playing [[HarderThanHard Inferno]] difficulty from the word go, which can net you weapons you can't even get in Normal.
* SerialEscalation: A player starts their career in the E.D.F. responding to a possible prank call about giant insects attacking. Lo and behold, giant ants are climbing all over the city and trying to eat the citizens. Wing Divers deploy to take advantage of the lack of flying insects, then giant spiders trap them in webs that stretch between office buildings. Giant leaping spiders show up in massive swarms. Finally, the Ravagers come back on the scene with dozens of Hectors and their humongous Mothership. This is a summary of the first 12 missions out of 80. This will get to the point where just giant ant swarms are viewed as the good old days.
* ShootEverythingThatMoves: Pretty much the objective of nearly every mission is to find everything that isn't a fellow EDF soldier and shoot it until it dies.
* ShortRangeShotgun: Some of the shotguns are not good beyond point blank ranges, while others subvert the trend quite nicely.
* ShoulderCannon: The Fencer can use various shoulder-mounted weapons, including shoulder mounted cannons.
* SniperRifle: Several varieties of sniper rifles show up namely for the Wing Diver and Ranger classes. There are even sniper cannons for the Fencer.
* SpentShellsShower: Some of the high rate of fire high ammo capacity weapons will eject a shower of shells when being fired.
* SpiderTank: The Depth Crawler is a four legged tank variant piloted by players. It takes the spider part of spider tank quite literally with the Depth Crawler able to move up walls and across ceilings just like a spider. It can also leap around just like the jumping spiders in the game.
* StarterEquipment: All player classes start out with a basic weapons set until they can start collecting additional weapons via drops.
* StickyBomb: The Air Raiders signature weapon. It fires a variety of projectiles that stick to their targets before being detonated.
* SuperPersistentMissile: Many of the missiles will constantly chase the target until it hit or hits an intervening object.
* SwordBeam: Some of the Fencer's sword weapons shoot out a energy blade beam. One variant is able to hit a target 500 meters away as its Level 3 attack.
* TankGoodness:
** The E5551 Gigantes tank, which is similar to the one from ''Earth Defense Force 2017''
** The Negring Self-Propulsion Rocket Tank, a MacrossMissileMassacre tank.
** The Epsilon Armored Railgun. More of a [[KineticWeaponsAreJustBetter Self Propelled Rail Gun artillery then a tank.]]
** The E651 Titan armed with the Requiem Gun. When fired it recoils hard enough to push the tank around.
* ThereIsNoKillLikeOverKill: Nothing is stopping you from calling a missile strike to deal with a handful of ants.
* TripodTerror: The aliens deploy tripod war machines that use leg mounted lasers for BeamSpam, {{PlasmaCannon}}s, and their spiked feet to attack the player.
* TwentyMinutesIntotheFuture: The games plot takes place 8 years after the events in VideoGame/EarthDefenseForce2017. The EDF and the rest of the earth have taken the technology of the Ravagers after having defeated them and used it to rebuild the earth. Elements of that same technology also went into rebuilding and improving the EDF giving us the four character classes.
* UrbanWarfare: Many sections of the game take place in cities with a variety of buildings. The built up areas are meant to look like various parts of Japan's urban landscape in a vague way.
* UtilityWeapon:
** Weapons that use explosives can be used to clear out areas congested by buildings, creating room for a killing ground and denying the aliens a high place to attack the player from. It is not an uncommon tactic for players laying deployable weapons or equipment to level surrounding buildings with explosive weapons before luring enemies into the deployable weapon kill zones. Due to how vehicle drops work, clearing out some space can make room for players to receive the larger vehicles.
* VillainForgottoLevelGrind: Fully averted. The E.D.F. used the 8 year gap to improve their military power, but the bugs were evolving into more dangerous forms during that time. The Ravagers themselves brought more forces from home, and continue to unveil new weaponry as the war goes on.
* WalkingTank:
** Did you think this military has those fancy-pants [[ImpossiblyGracefulGiant Japanese models]] for their giant robots? Nope. Every mecha is slow, turns like a drunken whale, and won't get you to the other side of the city in less than 15 minutes. That's okay, since the bugs will come to you.
** In EDF 4.1 the Depth Crawler SpiderTank is directly referred to as "the new tank" when it is dropped off by the choppers.
* WaveMotionGun: A late tier/end game Wing Diver weapon that fires a giant forward traveling wave of energy that flattens multiple city blocks and pretty much kills any enemy it hits. The game lists it as a "Grenade Launcher".
** Motherships employ a "Genocide Gun" that fires a powerful sweeping laser that can flatten city blocks and fry soldiers [[OneHitKill in one go]].
* WeWillUseLasersInTheFuture:
** The EDF has developed energy weapons from studying Ravager technology.
** For the Ranger and Fencer, there's a reason to have them as a secondary gun. The weapons have high damage and a high rate of fire. They can be found in lower difficulties/stages. Unfortunately since these classes don't have reactors to recharge them on the battlefield, they can't reload.
** Wing Divers use a wide variety of laser weapons that are recharged off the wing divers built in reactor.
** The Air Raider can even call in laser cannon strikes from a satellite in orbit.
* ZergRush: The main insect tactic is to swarm the enemy until nothing remains.
