In the 14th Century a quarrel over English succession to the French throne escalated into what history would call the Hundred Years' War. The ongoing war exhausted the standing armies of both sides and dependency on mercenary soldiers grew.

This game from {{Koei}} is loosely based on UsefulNotes/TheHundredYearsWar, with many gameplay elements from the VideoGame/DynastyWarriors series. The player creates and plays a single mercenary, but that character in turn can join or summon squads of soldiers to support him or her in battle. It's possible to run around unaccompanied, but it's very easy for a single soldier to be overwhelmed by enemy squads.

In 2015, this received an UpdatedRerelease in the form of ''Bladestorm: Nightmare''. Among several improvements are the ability to control up to four squad leaders, unlockable 'ace' characters, and a new 'Nightmare' mode story line that sees England and France [[EnemyMine forced to join forces]] against a massive army of fantasy creatures led by... [[FaceHeelTurn Joan of Arc?]]
!!This Game contains examples of:

* ActionGirl: There are a few female characters who fight for both England or France, the female rapier
units, and yourself if you choose a female mercenary character.
* AnAdventurerIsYou: Unlike most of the other Koei/Tecmo beat'em ups, you don't play a predetermined famous hero. Instead you are an anonymous mercenary of a particular skill set.
* AllYourBaseAreBelongToUs: Can be invoked by both sides. If the commander of the town is taken down, the town immediately falls under control of the other side. Great if it's your side that captured it, bad if the enemy forces captured one of your towns.
* AlternateHistory: While the game loosely follows events in RealLife, things can change. For instance, one mission has you save Joan of Arc when she's imprisoned.
* AnachronismStew: The game contains a lot of characters who never would have met in real life. For example, Edward the Black died long before Joan of Arc came around, but you may run into both of them in one map.
** Exotic units are also present which probably weren't present in 14th/15th Century France, such as elephant units, camel riders, and Asian units such as South China spearmen.
* AnnoyingArrows: Archer units, although usually more annoying when controlled by the player, as the computer controlled ones don't fire as often as a player can.
* AttackAttackAttack: Some squads can feel this way, often rushing headfirst into the first enemy group they run into. You can also invoke this trope on enemy troops by getting near them. They will usually attempt to overwhelm you unless you have friendly units nearby as well.
* AuthorityEqualsAssKicking: Pretty much every named character you encounter on the battlefield. Some are tougher than others though, and will largely depend on if you're facing them with units that they're weak against.
* BadassCrew: You can be one if you're controlling a unit of soldiers who are strong against the current enemy forces you're currently fighting against. However, they can quickly turn into a RedShirtArmy if you encounter troops you're weak against.
** BadassArmy: ''Nightmare'' gives you command of up to four squad leaders; you can have them either split up and take down strategic sections of the map at the same time, or bring them together as [[ThereIsNoKillLikeOverkill a single, massive unit that can steamroll almost any opposition you come across.]]
* {{BFG}}: Some siege units for breaking down castle doors are large cannons. You can actually control them if you want, but they're not very good against mobile opponents.
* BoringButPractical: Cavalry units, particularly horses, are probably the most efficient troops to use on the battlefield due to the fact that they're strong against a lot of unit types, and more importantly, can run away quickly if you find yourself on the losing end. Just try not to run into any pikemen while they have their pikes down.
** Spears units are also very efficient. They don't have much in terms of weakness and can take care of many swords units (which are often the base commanders so that makes them very useful for base raiding.)
* ColorCodedForYourConvenience: English units are always red, while French units are always blue no matter which side you're on. [[GuideDangIt Do not mix this up]] or you'll find yourself wondering why you can't hurt the English soldiers when fighting for England while the blue French units are killing your guys left and right.
* CombatPragmatist: You are encouraged to be one, due to the nature of this game having units that are strong against some, and weak against others. For example, swordsmen decimate the rapier units that are often guarding small towns, but will quickly die to halberd units in larger towns, which in turn are decimated by rapier units. The game will also give you clues as to what units the one you are controlling are strong/weak against, so it's often a good idea to switch to different units depending on the situation.
* TheComputerIsACheatingBastard: On higher difficulty missions, enemy generals will often activate their bladestorm ability frequently, and seem to have a high health pool. They also hit rather hard unless your current troop levels are close to theirs, but even then they will make your squad seem like a RedShirtArmy, wiping them out rather quickly.
* CoolSword: The legendary Excalibur for the English and Durandal for the French.
* CripplingOverspecialization: The pikemen are the most blatant example of this trope. They are only good against cavalry, but get destroyed by almost every other unit. They also have an extremely limited attack options, which is to lay down their long spears in front of them, and a quick stabbing attack which has a long CoolDown.
** That said, however, they are extremely useful when you run into enemy {{Hero Unit}}s who are usually (but not always) on horseback.
* CurbStompBattle: Can usually happen when you're controlling mounted units such as cavalry, who are strong against most foot soldiers. But also played straight if you run into mobs of units who are weak against your current squad's weapons. However, they can utilize this trope against you as well...
* DeathByAThousandCuts: Usually played straight with archer units, particularly horse archers, whose goal is to circle enemy formations while pelting them with arrows. Can also be played straight when fighting a higher level enemy general, who often has a lot of health for you and your allies to whittle down.
* DiskOneNuke: In a roundabout way. The short story is, in nightmare, you are supposed to tackle 100 years war first and then do the new nightmare scenario, but that has an easy mode that even says it can be done with a fresh character. So you can play "Disk 2" Before going back and playing "Disk 1" with all the bonuses and upgrades you got for your character, ''Including'' all skill books for mundane classes, the speical ones don't transfer over.
* EasyCommunication: Like in Franchise/DynastyWarriors, you can always see where units are, and where enemy and friendly generals are located. In addition, when you take over a town, you'll get congratulated by a friendly general even if they are on the other side of the map. Also, when generals are defeated, they will say something to you before they leave the battlefield for a few minutes, particularly if you defeated them.
* EasyLogistics: You never have to worry about feeding your troops, and for troops that have an ammo supply, if you run low while out in the field and can't make it back to a friendly town to refill, you can simply un-control them for a few moments, and then when you take control of them again, they'll have magically restored some of their ammo on their own.
* GangUpOnTheHuman: Zigzagged. While enemy formations do generally try to go after you, they will also attack friendly units first if you're not the closest thing to them first. Usually played straight with enemy generals, who often will go after you first even if they're engaging allies at the time.
* GunsAreWorthless: Played with, you can get guns in this game, and they are extremely powerful with only a few weaknesses, but they have a lot of pre-requisite quests, and you won't acquire them all until late in the game. But someone siding largely with the French units will run into said missions sooner than someone siding mostly with the English.
* HeroMustSurvive: While your soldiers can be sent off to die without you, if your character is defeated in battle, the mission ends immediately, and your only reward is whatever pitiful items you managed to grab before being defeated. You are also sent back to the tavern.
** Averted for the most part in ''Nightmare'': if one of your squad leaders is defeated, you are automatically swapped to one of the other ones you control and the battle keeps going, though the defeated player character doesn't return to the fight until the next day. You can still lose the mission completely if ''all'' of your squad leaders are defeated, however.
* HitAndRunTactics: Main use of cavalry units, who has a charge attack, an attack to let them get out of being surrounded, and a defensive ability. One English campaign also falls into this trope, where your objective is to take over several towns near each other (although you can take your time if you want to take over other towns first)
* HoldTheLine: You can theoretically do this with any troops, attempting to slow down enemy forces by engaging them until you can either defeat them, or at least buy enough time to escape. Also taken literally with one of the pikemen's attacks, where they brace themselves on the ground while holding their extremely long poles in front, which will usually destroy any mounted troops foolish enough to run into it. However, keep in mind this applies to you as well when controlling a mounted unit.
* InstantWinCondition: When the town's enemy commander appears, if you can defeat him, every other enemy unit in the town will disperse and flee, and the town immediately falls under your faction's control.
** Likewise, if you have a mission to accomplish, such as "take these 3 towns", the battle will end as soon as you capture the last objective.
*** Perfectly [[JustifiedTrope justified]]: That condition is the one on your mercenary contract. Would would you risk your life for a second longer than what you were paid for?
* InvincibilityPowerUp: When you activate "Bladestorm" mode (via a full morale bar, gained largely from killing enemies, but can also be acquired by touching deer or an enemy dropping a wine bottle, and fills gradually when your health bar gets low), where your character/squad is immune from damage, and can attack/move around much faster. However, keep in mind that enemy generals can also activate this ability, and on harder missions [[TheComputerIsACheatingBastard will do so with impunity.]]
* LeeroyJenkins: Joan of Arc does one in one mission, and the player can invoke this as well if they rush towards an enemy stronghold or large group of enemy troops before their backup can get there.
* NoArcInArchery: Largely played straight. They do arc if you fire from an extremely long distance, but most fights take place up close so you may not notice it. Averted with one ability longbowmen receive, where their shots do arc and can be fired from a much farther distance than a regular straight shot.
* OneManArmy: Can be played straight, but usually not recommended due to the game's emphasis on squad and army battles consisting of large groups of people fighting. You can get quickly overwhelmed if you try to take on 50 guys by yourself. However, you do move faster on your own (second only to mounted units), so if you're in a losing fight, you can run away much quicker by releasing control of your current unit. But if a mounted unit is chasing you, you can't outrun them and they're hard to outmaneuver due to most fights taking place in open fields.
* OneSteveLimit: Averted. England has ''three'' Johns.
* PrivateMilitaryContractors: You are essentially a medieval equivalent of one. The game mentions the heavy use of mercenaries on both sides, and you can change sides freely with no repercussions whatsoever. So you could theoretically take over one town for the English in one mission, then the very next mission requires you to take back that town for the French.
* TheSiege: The Siege of Orleans mission. If you side with the English, you have to HoldTheLine in Orleans long enough to escape, while siding with the French will have you assault Orleans and drive out the English instead. Also played straight with larger, walled towns, where you need siege equipment to break the doors down in order to attack it.
* StandardStatusEffects: There are a couple in the game, such as being on fire draining health, but like most other games, they're not practical in most areas, so you're still better off just killing everything as fast as you can.
* TacticalRockPaperScissors: There are a variety of units in the game that you can control, and each has their own strengths and weaknesses against various other troops. For example, swordsmen are strong against rapier users, but they get defeated easily by halberds, who in turn get destroyed by the rapier units.
* TakeYourTime: While many missions are limited in scope (usually 3-6 days, which each day lasting about 10 minutes or so), story missions have an "indefinite" time period, meaning you can conquer the entire map for your side before doing the actual mission if you wanted to
* TookALevelInBadAss: Played straight with Joan of Arc. When you first meet her, she's just a peasant girl on foot without much combat abilities who gets defeated easily. Later on, she's wearing plate armor and riding on a horse leading an elite unit of cavalry.
** Can also apply to the player as well, who's fairly weak as well in the beginning, but as they gain experience and knowledge of the various types of troops and their [[TacticalRockPaperScissors strengths/weaknesses]], can quickly learn to adapt to changing situations.
* VendorTrash: Enemy officers and captured bases can drop a variety of "replica" artworks that sell for very small amounts of money.
