''Iron Brigade'' (formerly known as ''Trenched'') is {{Creator/Double Fine}}'s fourth downloadable game as part of their Amnesia Fortnights venture, changing the studio from making one large title every few years to making multiple small games in one year.

The year is 1926, and the world is being invaded by monsters made completely out of primitive television sets known as ''Monovisions'' or ''Tubes'', which no conventional military has been able to defeat. The only force capable of facing them is the Mobile Trench Brigade, an elite squad of soldiers trained to use [[HumongousMecha Mobile Trenches]], which are quite literally WorldWarOne trenches slapped on a pair of robot legs, with a human soldier operating the whole thing from inside the trench.

It all began during WorldWarOne, when American soldier Frank Woodruff survives getting his legs crushed by a tank and is reassigned to a radio listening post in the Pacific to listen in on enemy radio transmissions. While there, he befriends Vladimir Farnsworth, another crippled soldier. While working, they listen in on an unknown signal, later dubbed the "Broadcast", that killed all who heard it except for Woodruff and Vlad. Instead, they gained supernatural genius.

Woodruff used his newly found genius to invent mobile robotic legs to help his fellow disabled veterans. Vlad used his gifts to invent the "Monovision", in an attempt to bring the world to the comfort of your home. Unfortunately, the end result was the horrors of the world coming straight to him (along with really crappy programming), which [[OldMediaAreEvil drove him to insanity]]. Vlad then created a race of mechanical monsters made entirely of television sets, which shared the name of Vlad's invention. Colonel Woodruff equips the mobile robotic legs he developed with weapons, and forms the Mobile Trench Brigade to fight his former friend's creations.

The game is a SpiritualSuccessor to ''VideoGame/BrutalLegend'', with a slant towards ''VideoGame/MondayNightCombat''. Rather than commanding free roaming units like a RealTimeStrategy game, the game combines action with TowerDefense. Each player has the ability to customize their Mobile Trench with over 200 different parts. The Trenches are divided into three types, [[JackOfAllStats Standard]] Trenches balancing weapons and turrets, [[TheEngineer Engine]][[FragileSpeedster ering]] Trenches with lighter weapons but more turret emplacements, or [[MightyGlacier Assault]] Trenches with limited turrets but the greatest weapons capacity.

The game was originally published by Microsoft and released in 2011 for UsefulNotes/{{Xbox 360}}, then in 2012 for UsefulNotes/MicrosoftWindows, bundled with Games for Windows Live in the latter case. On May 28, 2015, Double Fine got the IP rights the PC version of the game was switched from Games for Windows Live to Steamworks for matchmaking, squashing several {{Game Breaking Bug}}s in the process.
!! This game provides examples of:
* AlternateHistory: Television is invented several decades early [[OldMediaAreEvil and it's evil.]]
* ACommanderIsYou: The player can deploy defensive towers, like in a TowerDefense game.
* AmbiguousRobots: The Tubes, which are built out of machine parts but have an otherwise very organic looking structure.
* ArtisticLicenseEngineering: While the Trenches' schematics aren't available, one could guess that [[PercussiveMaintenance punching or kicking the controls]] shouldn't revive your Trench if it broke down.
* ArtisticLicenseHistory: [[RuleOfCool Not like anyone minds, though.]]
* AwesomeButImpractical: The Trenches, before they were re-purposed as weapons, would appear to have been very ungainly as a prosthetic, being very bulky and adding at least 5 feet to the operator's height.
** Gameplay-wise, Artillery Cannons. Single shot, arcing projectile, long reload, big explosion and high damage. Also, the Gungnir Sniper Cannon, which is single shot and takes much longer to reload than other Sniper Cannons, but has some of the highest damage in the game. Both can be made SimpleYetAwesome when combined with the Quickload ability and some aiming skill on the part of the player, or in the case of the "Mr. Pancakes", a MIRV launcher that not only drops a line of grenades along its arc, but a line of [[HomingProjectile MAGNETIC]] grenades, which can be a bit of a GameBreaker when combined with the Quickload ability.
* BeardOfEvil: Vlad.
** On the cover of the in-universe Mad Scientist magazine, one article is titled "Which Sinister Beard is Right for Me?"
** In the DLC even the [[spoiler:Bear]] has one.
* BadassMustache: Several.
* BarrierWarrior: Jacobs, which project a shield on any nearby Tubes. Although, not on themselves or each other...
* {{BFG}}: Any Artillery Cannon qualifies (especially "The King" and "Mr. Pancakes"), and even some Sniper Cannons too.
* BigBadFriend: Vladimir Farnsworth. The entire story revolves around him and the BigGood.
* BrownNote: The "Broadcast". It killed everyone who heard it except for Vlad and Woodruff, who gained superhuman intellect instead.
* BigGood: Commander Woodruff.
* ColorCodedForYourConvenience: Blue enemies focus on attacking defense objectives. Teal enemies focus on attacking emplacements. Red enemies focus on attacking the Trench Marines.
** Trench weapons also have this treatment, from White (regular), to Green (uncommon, is stronger and/or has a basic ability), to Blue (rare, is even stronger and/or has even better abilities), to Purple (very rare, but is also very powerful and/or has top-grade abilities). Red weapons are also available in the ''Rise of the Martian Bear'' campaign, which are even stronger.
* ComesGreatResponsibility
* CoolBoat: The USS [=McKinley=], a re-purposed aircraft carrier with a crapton of extra guns and ''legs''!
** CoolStarship: Becomes one in ''Rise of the Martian Bear''.
* DeathRay: Broadcasters, weaponized [[ExactlyWhatItSaysOnTheTin broadcasters]] which also have some gameplay elements reminiscent of [[VideoGameFlamethrowersSuck flamethrowers]].
* DieselPunk: Swimming in it. Everything is made of steel, consumes vast quantities on plentiful gasoline, belches smoke, and is incredibly overbuilt.
* DownloadableContent: ''Rise of the Martian Bear'', which provides a new campaign (set on ''Mars!'') with new, stronger enemies and Trench equipment. Is included for free with the PC version.
* EasyLogistics: The Trenches burn through five-thousand gallons of gasoline perk Trench per ''week''. Good thing your supply is uninterrupted.
* TheEngineer: The player characters, all of whom can place [[SentryGun turrets]] almost anywhere. Different trench chassis play the trope slightly differently, being able to deploy different turrets.
** Engineering Trenches trade firepower for the ability to place a wider variety of turrets. They are also {{Fragile Speedster}}s, as they lack armor but move quickly.
* FightingYourFriend
* FlauntingYourFleets: Subtle, but while on the deck of the [=McKinnley=], players can see vast number of bombers flying air cover above the ship in perfect formation.
* FunnyForeigner: Josef Kowalski, a [[UsefulNotes/PolesWithPoleaxes Polish trench marine]], is sometimes played like that, complaining about his equipment and taunting Monovisions in a cheesy accent. Ditto for Claude Stanley, except his accent is that of a [[IAmVeryBritish stereotypical Brit]].
--> '''Kowalski''': "[[MadeInCountryX Polish gun]] would be ready by now!"
* GenreBusting
* GiantSquid: A mechanical one serves as the Pacific campaign's boss battle.
* HandicappedBadass: Both Colonel Woodruff and Vlad Farnsworth. Bonus points go to Woodruff, who commands the Mobile Trench Brigade from the comfort of an Iron Lung with robot arms for both typing and holding his cigar. [[spoiler:Vlad's handicap? Prolonged exposure to the raw, unfiltered Broadcast has turned him into an infant with an adult's head (somehow without damaging his superhuman intellect).]]
* HeavilyArmoredMook: Breakers. [[DidntNeedThoseAnyway Changes]] once they're hit with an explosive weapon, though they can be killed without using them.
* HoldTheLine: Every level, except the ones against bosses.
* HumongousMecha: The Mobile Trenches.
* IndecisiveParody: It's not completely clear whether the game falls under RatedMForManly or TestosteronePoisoning, at times obviously parodical in its extreme "manliness", but other times seeming to play it straight.
* MadScientist: Vlad.
* MechanicalMonster: The Monovisions are as much machine as creature, and more disturbing to look at than either would be alone.
* MissionControl: Woodruff serves as this from his iron lung on-board the USS [=McKinley=].
* MookMaker: Big Bertha.
* MoreDakka: A single Assault Trench can be outfitted with up to ''six'' machine guns, some of which have multiple barrels.
** On top of that, it can be assisted by even more machine gun turrets.
* NiceHat: Not to VideoGame/TeamFortress2 levels, but your character can wear many nice hats, including a sombrero, a fez, a welding mask, and [[VideoGame/{{Psychonauts}} Razputin's famous PSI-helmet and goggles]].
* NoExportForYou: The European version of the game was taken down within hours of its release due to copyright issues regarding the game's title in Portugal, which prompted an unusually radical solution (see OrwellianRetcon)
* OldMediaAreEvil: Taken to extremes, and played for laughs. Vlad invented television decades before it was invented in real life. Because of this early development, the horrors of the world coming to him, combined with the resulting programming being so primitive and crappy, drove him insane.
* OrwellianRetcon: Due to EU copyright issues with the name ''Trenched'', the game's name was changed in ''all'' territories to ''Iron Brigade''.
** There is a technical reason for the change affecting all regions: If the EU was the only region going by ''Iron Brigade'' and everywhere else was ''Trenched'', EU players would be limited to multiplayer with only other EU players (an issue with games with two different names connecting over Xbox Live).
* PinballProjectile Sniper Cannons with the RICOCHET and RICOCHET+ can act like this.
** The "Rise of the Martian Bear" DLC adds all sorts of oddball weapons, including RICOCHET Machine Guns (the "80-UNC3 Indirect MG"), of which the flavor text says, "One would think that years of technological advances were involved in the creation of this weapon. In actuality, we just filled it with spring-loaded bullets, and somehow it worked."
* RatedMForManly: Double Fine was inspired by silly [[http://bitmob.com/articles/the-manly-mans-mens-magazines-of-double-fines-trenched-for-men "manly man" magazines]] from TheForties and TheFifties. They use the magazine shown in this trope's page as source material!
* RedOniBlueOni: Woodruff and Farnsworth's inventions are spiritual opposites of each other. Woodruff's HumongousMecha are intended to let disabled veterans walk again. Farnsworth's Monovision was intended to being the world to you instead.
* RealIsBrown: DefiedTrope.
* SandWorm: The Africa and Europe bosses.
* SchizoTech: Monsters made out of TV sets, trenches slapped on mech legs, and a gigantic aircraft carrier with legs that gets turned into a spaceship.
* SentryGun: The player-deployed turrets.
* SequelHook: Even after defeating Vlad, Woodruff states that the source and purpose of the "Broadcast" is unknown and that it may return.
--> '''Woodruff''': ''"I do know one thing, that we'll be ready for it."''
* ShotgunsAreJustBetter: In addition to shotguns for your Trench, your most basic turrets have shotguns.
* ShoutOut:
** ''"Sucks to be [[YouTube you, Tube!]]"''
** Players can dress up their avatar like [[VideoGame/{{Psychonauts}} Razputin.]] You even get an achievement for doing so! Later costumes include [[VideoGame/BrutalLegend Eddie Riggs]], [[VideoGame/CostumeQuest a cardboard robot]], and [[VideoGame/{{Stacking}} a matroyshka doll bandolero]].
* {{Showrunner}}: Brad Muir.
* SimpleYetAwesome: Purple quality weapons usually have incredibly useful effects as well as high damage, such as a [[MoreDakka fully automatic]] shotgun or a machine gun with [[StuffBlowingUp exploding rounds]]. [[RandomlyDrops Good luck finding one, though.]]
* SmokingIsCool: Woodruff, hilariously, has an attachment on his iron lung meant specifically to hold his cigar.
** The Marine also dons a cigar before repairing his trench, should it be downed.
** Heck, the Mobile Trenches themselves have a built-in cigar humidor, just to make sure the pilot always has a supply in good condition.
* SpiritualSuccessor: Double Fine likes to call the game "[[{{ChromeHounds}} Trench Hounds.]]"
* StealthPun: "This one's for [[YouTube you, tube!]]"
* SuicideAttack: The Blitzers' and Knobs' only form of attack, consisting of running/rolling to your location and blowing up in your face.
* TauntButton: While on the ship, the fire buttons (LT/RT for Xbox, L2/R2 for PS3) instead let your marine "salute". Depending on what kind of hat you're wearing, it can range from an actual military salute to various silly gestures.
* TestosteronePoisoning: They were shooting for this at least ''some'' of the time, but how often as opposed to straight RatedMForManly can be hard to tell -- see IndecisiveParody above.
* VoiceOfTheLegion: Vlad.
* WarHasNeverBeenSoMuchFun
* WellDoneSonGuy: Woodruff Jr.
* WithGreatPowerComesGreatInsanity: Vlad.
* ZergRush: The Blitzers and Knobs, who suicide rush players and turret emplacements respectively.
