[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/samurai_warriors_4_empires_2015_09_17_15_013_1.jpg]][[caption-width-right:350:Enjoy the ultimate battle for supremacy in the Warring States Era!]]

''Samurai Warriors'' started as a spinoff of Creator/{{Koei}}'s ''VideoGame/DynastyWarriors'' HackAndSlash series, porting the gameplay elements to a new setting: the UsefulNotes/SengokuPeriod of Japanese history.[[note]]Hence its Japanese name "[[PunnyName Sengoku Musou]]," compared to ''Dynasty Warriors'' being "Shin Sangoku Musou."[[/note]] Its success has lead to it becoming its own series, with a total of 4 main installments, all with their own offshoots and expansions. The playable scenarios span fifty years of Japanese history, and playable characters include [[UsefulNotes/OdaNobunaga Nobunaga Oda]], [[UsefulNotes/TokugawaIeyasu Ieyasu Tokugawa]], [[UsefulNotes/ToyotomiHideyoshi Hideyoshi Toyotomi]], [[UsefulNotes/SanadaYukimura Yukimura Sanada]], [[UsefulNotes/IshidaMitsunari Mitsunari Ishida]], [[UsefulNotes/MiyamotoMusashi Musashi Miyamoto]], [[UsefulNotes/HattoriHanzo Hanzo Hattori]], [[UsefulNotes/FuumaKotaro Kotaro Fuma]], and many more. It should be worth noting that each version loosely sticks to a certain time frame and focuses on specific moments: case in point, the first game is all over Nobunaga while the second game's primary focus are the events leading to Sekigahara, and the third appears to try to cover just about everything in-between. The ''Chronicles'' games covers the whole lot, however.

Some of the playable battles:
* September 10, 1561: The Fourth Battle of Kawanakajima: Takeda vs Uesugi
* January 25, 1573: Battle of Mikatagahara: Oda vs Takeda
* June 28, 1575: Battle of Nagashino: Oda vs Takeda
* June 21, 1582: The Incident at Honnoji; Nobunaga Oda vs [[UsefulNotes/AkechiMitsuhide Mitsuhide Akechi]]
* July 4, 1582: The Battle of Yamazaki: [[UsefulNotes/AkechiMitsuhide Mitsuhide Akechi]] vs Toyotomi
* October 21, 1600: The Battle of Sekigahara: East (Tokugawa) vs West (Ishida)
* Winter 1614 - Summer 1615: Siege of Osaka Castle: Tokugawa vs Toyotomi
and many, many more

Some scenarios are AlternateHistory tales, such as Nobunaga surviving Honnoji and uniting Japan, or Hideyoshi faking his death in 1598 and appearing at Sekigahara (both examples are their respective hidden "Dream Stage" battle). In other cases, some of the "Dream Stages" are just for fun, like Tadakatsu taking on all worthy warriors in a champion's tournament or Nohime and Oichi's beauty contest battle (made even funnier if played with the ''[=SW2=]: Xtreme Legends'' expansion).

The voice acting is goofy at times (witness Hideyoshi declare, "Let's make our enemies beg us for peace!" and badass Tadakatsu Honda's borderline lisp), and the difficulty encompasses downright stupid allied [=NPCs=] and enemy officers who love to gang up on you, but at least you'll learn a little something about Japanese history; just remember that Tokugawa Ieyasu did not actually fight the Battle of Sekigahara with a giant spear that shot cannon balls and doubled as a flamethrower.

----
!This franchise features the following tropes:
* AluminumChristmasTrees: Western neophyte players in particular might just be surprised at how much of what's presented in these games is based closely on ''historical fact''. For example, the "star-crossed lovers" arc for Oichi and Nagamasa Azai? Yep, that one's out of Japanese history, as is [[spoiler:her death at Shizugatake, albeit the game has her fighting alongside Katsuie Shibata, who was her husband after Nagamasa, instead of committing ''seppuku'' with him]].
* AltarDiplomacy: Nagamasa-Oichi, Nobunaga-No, and Nobuyuki-Ina. Other than them, it's pretty common for the era.
* AndYourRewardIsClothes: In ''Chronicles 3'', you can have the protagonist wear another playable character's outfit once you get their friendship high enough.
* ArtificialStupidity: In the ''4'' games, the horse tends to run circles around you instead of actually coming directly at you if you hold the Call Horse button, meaning you could get halfway to your destination before actually mounting your steed.
* ArtisticAge: For essentially the same reason as [[DynastyWarriors the parent series]], most of the characters' designs are meant to be either at their prime or at the earliest age they could potentially appear with only a few being older than that. This leads to cases like Hanbei looking extremely young compared to Kanbei, despite the fact that he's ''older'' than him, or Ieyasu looking as if he's the oldest of the Three Unifiers (in reality, he's 6 years younger than Hideyoshi and 9 years younger than Nobunaga). ''Spirit of Sanada'' avoids this for the most part because [[PlotRelevantAgeUp the plot actually follows Yukimura and others from infanthood to the day of his death]], but it is nevertheless still present with Kunoichi and Sasuke, both appearing in Osaka Castle looking not a day older than when they meet the Sanada brothers as children.
* AutoScrollingLevel: Samurai Warriors Katana for the Wii which is this but with a Kantana (or others).
* AwesomeButImpractical: Less Awesome but more fun, In ''[=SW2=]'', Nene has a skill in which she can transform into any nearby character...even enemy ones. Yes, even those countless mooks you'll probably spend a lot of your time mercilessly butchering.
** In ''[=SW2=]: Empires'', custom characters using the sword, spear, naginata or Nene's moveset can use this skill too.
* BadassAdorable: ''Spirit of Sanada'' allows you to play as eight-year-old Yukimura. He's so cute running around beating grown men into submission with his stick.
* BadassBoast: Chock full of them, like any ''Warriors'' game.
-->'''Tadakatsu Honda:''' I am a man of peerless might!
* BadassGrandpa: Takeda Shingen, Shimazu Yoshihiro, Hojou Ujiyasu, Mouri Motonari (in ''4'', at least), and eventually Tokugawa Ieyasu himself at the end of ''Spirit of Sanada''. There's even "elderly" type generic officer.
* BittersweetEnding: All throughout the series, but ''4'' in particular highlights it. Since in that iteration there are no "what-if" or "alternate history" scenarios, everyone meets their end accordingly. Playing the Western Army during Sekigahara is arguably the harshest of the moments.
* BolivianArmyEnding: Games that depict Yukimura Sanada taking part in the Siege of Osaka tend to end with him making a final headlong charge at Tokugawa's army, ending with Ieyasu saluting him as a WorthyOpponent, as he did according to legend.
* BottomlessMagazines:
** All of the gun-type weapons have unlimited ammunition and don't need to be reloaded manually by the player (but there is a token effort at animating reloads during combos). Generic NPC riflemen reload between shots, though.
** It's worse with Masamune Date, because he can rapidfire his pistol, spraying waves with his Musou.
** Magoichi Saika's special move starting in 2 is to aim in a single direction and rapid fire his musket as long as the special attack button is held down, with a firing rate that most modern semi-automatic rifles would have trouble matching.
* {{Bowdlerise}}: AdaptationalHeroism and [[AdaptationalVillainy Villainy]] aside, some events and things significant during the Sengoku period are noticeably not featured in the series. The two most glaring ones are:
** UsefulNotes/JapaneseChristian. Historically, Christians were a major population in Japan during the Sengoku period and many daimyos, particularly in Kyushu, converted to gain better benefits of trade with the Europeans. Yet, the religion or the Europeans in general didn't get a single mention in the series, although two characters in the game (Kuroda Kanbei and Gracia) were Christian in real life (their "exoticism" is instead symbolized by their mystic and supernatural weapon of choice). Their phasing out also conveniently ignores Hideyoshi's and especially Ieyasu's rather [[WitchHunt genocidal attempts]] to completely eradicate Christianity from Japan.
** The invasion of Joseon during Hideyoshi's reign is completely avoided, though this decision is probably [[TropesAreNotBad better to stay]], since it would lead to some unfortunate implications (and most likely a bunch of protests and boycotts). The less controversial conquest of the Ryukyu Kingdom is also not featured.
* BribingYourWayToVictory: The DLC weapons in ''4'' are more powerful than the ultimate weapons and while those are difficult and often confusing to obtain all you have to do for the DLC ones is navigate a menu. The mounts, while not quite as strong as Matsukaze, also have better stats than the majority available otherwise.
* BulletTime: Samurai Warriors 4's Rage Mode causes the movement of the regular "cannon fodder" soldiers around you to slow to such a crawl that it looks like you've stopped time. The named generals, however, are able to run around and attack as normal.
* CameraAbuse: In pre-rendered cutscenes, specially the first one of Oda or Noh, you can see blood splatter on the camera.
** In the fourth game, Mitsuhide and Magoichi's True Musou attacks involves them slashing/shooting at the screen, shattering it.
* CameraCentering: As per ''Warriors'' standard, blocking will immediately set the camera behind the player's back.
* CastFullOfPrettyBoys: While it's understandable that a game that revolves around battles fought in feudal times would have an overwhelmingly male cast, there's no reason for so many of them to be so damn [[{{Bishonen}} pretty]]. The first had a few pretty boys, but by the fourth game, it's taken to an extreme. [[TropesAreNotBad On the other hand]], unlike ''VideoGame/DynastyWarriors'' characters, this might be justified with the fact that, some ''Samurai Warriors'' characters historically did gain fame when they're still considerably young, and this is sometimes stated in the game's story.
* CatchPhrase: The characters' personal variations of "Enemy Officer Defeated".
* ChuckCunninghamSyndrome: Starting from ''2'', scenarios about Nobunaga's conflict against the Ikko-Ikki sect in Ise Nagashima is removed altogether to tone down Nobunaga's former EvilOverlord looks. As a result, Honganji Kennyo is never mentioned or even be featured as an NPC again in future SW games.
* CounterAttack:
** The special move of several characters has them briefly enter a defensive stance from which they will automatically dodge and retaliate if hit.
** The simplest way to trigger a Mighty Strike in ''4'' is to block the officer's attacks with perfect timing.
* CriticalAnnoyance: Whenever an officer is just knocked down but barely took a scratch damage.
-->'''Hideyoshi Toyotomi:''' Gah! Where are my reinforcements!
-->'''Ginchyo Tachibana:''' Don't waver! The Tachibana will not be beaten!
* CriticalExistenceFailure: Every CPU-controlled officer is this. It's even worse if your side's morale is too low or if they are generic officers.
* DarkReprise: The final stage of ''Chronicles'', the Osaka Summer Campaign, features a melancholy remix of the main theme, fittingly titled "Grief".
* DarkerAndEdgier: ''4'' compared to previous games in the series, as it features only one story, and that is the historical route, so there's no saving of a character if they are doomed in a particular battle. As a whole, the series is darker than its parent series. While ArtisticLicenseHistory is employed, mature themes generally avoided in ''Dynasty Warriors'', including arranged marriages, explicit murders, and suicides are present here.
* DefeatMeansFriendship: ''Chronicles'' depicts Kanetsugu joining Masamune Date as this, following the Battle of Hasedo. Expecting to be executed, Kanetsugu is instead surprised by an offer to join his enemy, who recognizes his great skill and potential.
* DepartmentOfRedundancyDepartment: Hideyoshi's 'One-day Castle' song back in the first game (in Siege of Inabayama) is this:
-->''Beeeehold the castle, that is built in just one day!\\
What genius could have done this, you say?\\
It's Hideyoshi, Hideyoshi we praise!\\
Who built the castle in just one day, wheee!\\
It's Hideyoshi, Hideyoshi we praise!\\
He built a castle in just one day!!
* DesperationAttack: In most games, the health bar changes colors depending on how much health is left, with red being the lowest and an indication the player will die soon if further damage is sustained. When a character's health bar reaches the "danger zone", they can use a "True Musou Attack", which is more powerful than a normal one and has the fire element attached. The Musou Gauge also charges gradually while HP is low.
* DoubleJump: The ninja characters have this ability. Since ''SW'' is hardly a platforming-oriented series, its main use is to allow the player access to certain "ninja paths" that are too high up for most characters, which can significantly aid mobility in a few missions.
* DoubleMeaningTitle: The 'II' in Samurai Warriors 4-II both refers to it being the second iteration of Samurai Warriors 4, and to Naomasa ''Ii'' (spelled with an upper case and lower case 'i'), the sole new character for the game.
* EarlyInstallmentWeirdness:
** The first game had castle stages where you play your character alone without allies. Depending on your perspective, this might not be a bad thing, and actually offer a fresh challenge, but as it proved divisive it was cut from subsequent entries although it's available in Challenge Mode for some later games.
** The first game also gave all characters a ranged attack with unlimited ammunition. Most characters used bows while Goemon used his BackpackCannon and Magoichi used his musket. Fulfilling certain conditions in the Edit Officer Training Mode granted Edit Officers the ability to use a musket too, but only for ranged attacks. This was completely dropped starting in ''Samurai Warriors 2'' and replaced by the special stances.
** The first Empires expansion, ''Samurai Warriors 2: Empires'', is a meta example: while there's nothing especially strange within the game itself, it was released '''before''' 2's ''Xtreme Legends'', which is the opposite of how it's usually been done.
** In the first game, if you stayed on a certain stage for a while, you could see the stage gradually change from day to night. One good example of this is Okuni's stage Dance Of Ise.
* ElaborateEqualsEffective: Played straight with the various weapons.
* EscortMission: Hampered by bad AI, par for the course with any others.
** Particularly noticeable in the first game if playing on the Oda side at Honnouji as anyone except Nobunaga, as when he's a NPC he absolutely ''insists'' on killing any and all enemy peons in the way instead of high-tailing it to the escape point.
** ''Chronicles'' gives the player options for making these significantly easier or harder; when you can play as the character you're supposed to be escorting, you can avoid all enemies and run to the objective. The same applies when the objective is for the character to escape the battlefield, but this has the downside of giving you one less playable character for the rest of the mission.
* FamilyThemeNaming: Many famous clans named their members with certain theme naming. 'Yuki' for Sanada (Masayuki, Yukimura, Nobuyuki), 'Tada' for Honda (Tadakatsu, Tadatomo), 'Hide' for Toyotomi (Hideyoshi, Hideyori), 'Nobu' for Oda (Nobunaga, Nobutada), 'Chika' for Chosokabe (Motochika, Morichika, Nobuchika), 'Moto' for Mouri (Motonari, Takamoto, Terumoto, Hidemoto), 'Kage' for Uesugi (Kagetora[[note]]which is also Kenshin's birth name, hence he gave the name to one his adopted sons[[/note]], Kagekatsu), 'Uji' for Hojou (Ujiyasu, Ujimasa, Ujinao), 'Mune' for Date (Masamune, Terumune, Hidemune), and the list goes on!
* {{Fanservice}}: Since second game, almost every female character is attractive and many of them have revealing outfits.
* {{Flanderization}}: Par for the course with Koei and expanding character rosters.
* GaidenGame: Following up with ''VideoGame/SengokuBasara'' giving a GaidenGame for Sanada Yukimura, Koei Tecmo did the same with ''Spirit of Sanada'', even adding in Yukimura's father, Sanada Masayuki.
* GameBreaker: In 4, the ''Stimulus'' weapon perk. One of its effects is allowing for level-capped (level 50) characters to keep increasing their stats beyond what is possible without equipping a Stimulus weapon. But that isn't what allows players to break the game with it. Whenever a Stimulus-equipped character gains a level (or just fills up the XP bar for those already at level 50), they are healed, given full Spirit/Musou and a level 3 buff from each of the stat-boosting items. Including the one which prevents the Spirit gauge from depleting for 45 seconds. By activating Rage Mode and combining it with an XP Scroll (causes enemies to drop small XP-granting scrolls; the Level 3 scroll lasts for ''four minutes''), you can start to ''chain Stimulus effects together'', refreshing the stat buffs in the process. With enough enemies (and abstinence from using a True Musou Attack), you can have a perpetual Rage Mode for most - if not all - of a battle.
* GameplayAndStorySegregation: Playable characters can be unlocked for use as subofficers, albeit only useable one at a time. This makes it very possible to be say, fighting against Ranmaru Mori ''alongside Ranmaru Mori ''.
* GreyAndGreyMorality: A lot of the time. While some forces stand for loftier virtues than others, few, if any of them can be said to be squarely good or evil. The Oda vs Akechi incident is one of best ever-present examples; while Mitsuhide is presented as the more moral party, he commits his coup on the eve of unification and has to fight and slay his friends and comrades, including sympathetic characters such as Ranmaru and Oichi, in his quest to kill his lord. Particularly emphasized in the first game where Mitsuhide found himself having to suppress recalcitrant peasants by force - the same sort of behaviour he rebelled against Nobunaga for.
* GuideDangIt:
** Getting your ultimate weapons. All of them involve doing very difficult things at very specific points in the battle on Hard or greater difficulty. And there's ''no hint whatsoever'' in the game itself about what you're supposed to do.
** ''3'' is a bit better about this: you just have to complete every (usually optional) tactical advantage objective in a certain battle on Hard or above. ''Which'' battle is still guesswork, however.
** In ''Chronicles'' the fourth weapon will be granted after completion of a mission with a gold background. It will almost always be in a mission of particular significance to the character, such as "Chaos in Iga" for Hanzo and the Conquest of Odawara for Hideyoshi. If a character is only playable (prior to being unlocked) in a single mission, such as Okehazama for Oichi, that's probably where the weapon is. Sometimes the hidden requirements for the gold mission are obvious - if a mission pop up says "Don't let any allied officers die!" that's a helpful clue. Others - such as claiming all strongholds - are not.
* GrappleMove: Some characters have grab moves in their movesets, like [[FragileSpeedster Nene]]'s unblockable SpinningPileDriver grab move (though it's pretty weak). The Grabs' main advantage is that they are unblockable, with the obvious disadvantage of being rather hard to aim due to the combat being done in three dimensions.
** To note, this was no doubt carried over from its sister series ''Dynasty Warriors'' via its fourth installment, where it wasn't that refined (though it was revolutionary but soon removed). The second installment of ''Samurai Warriors'' managed to bring this mechanic back and improved upon it massively for the whole ''Musou Warriors'' franchise onwards.
* GrayRainOfDepression: Mitsunari's last scene in ''4''.
* HardModePerks: Like in VideoGame/DynastyWarriors, you get better weapon/item drops in all of the games and increased stat gain in the first game.
* HistoricalBadassUpgrade: Most of the cast. Granted, some of those ancient warriors were actually pretty badass on their own....
* HistoricalHeroUpgrade: A rather surprising treatment of [[UsefulNotes/OdaNobunaga Nobunaga Oda]] from the second game on (for [[AntiHero certain values of hero]], anyway).
* HistoricalVillainUpgrade: [[UsefulNotes/FuumaKotaro Kotaro Fuma]] may not have been a nice man, but he certainly wasn't a chaos-worshiping {{Troll}} in real life. It's averted, on the other hand, with Chronicle 2nd newcomer [[UsefulNotes/YagyuJubei Munenori Yagyu]]. He's been a victim of the trope so many times (''especially'' VideoGame/{{Onimusha}}), but for his debut, he's a willing supporter of the Tokugawa clan's efforts to end the war, and is all around a just, virtuous, badass swordsman. The fourth game, on the other hand, zig-zag this. Munenori is first seen hanging around with [[ObviouslyEvil Matsunaga Hisahide]], but only does so because he's bound by his code of honor to repay those who helped him, and apparently Hisahide did, so he became his NobleTopEnforcer. Once Hisahide bit the dust, eventually Munenori ended up in the services of Tokugawa and remains a helpful person to his fellow retainers. But considering Koei's tendencies to put the Tokugawa as the antagonists for their poster boy Yukimura, Munenori would eventually play an antagonistic role, but thankfully, right now he's at worst a Type IV AntiVillain.
* HitStop: The action slows significantly for dramatic reasons whenever an objective officer is defeated.
* HollerButton: The ability to summon a horse. If you don't have one, a generic one will appear. This was originally exclusive to Keiji, Yukimura and Toshiie, but the third installment made it universal. In ''Chronicles'', this ability is exclusive to the Green character, which is always the PlayerCharacter by default.
* HopeSpot: Hideyoshi's brief unification of Japan. In the eight years after Kanto is conquered, Japan is finally at peace; everyone can interact without having to carry weapons and there's no apparent conflict in the horizon. Then Hideyoshi dies and everything goes straight to hell again. It's vividly shown in ''4'', where a CGI cutscene after the Battle of Odawara stage shows all major daimyo of Japan still living at that time gathering for a jolly celebration with Hideyoshi at a park, a stark contrast to all other CGI cutscenes in the game.
* HourglassHottie: Like Dynasty Warriors, every female character is this.
* ImprobableWeaponUser:
** Yoshimoto Imagawa kicks a kemari (ancient oriental soccer ball) in almost all of his moves. His main weapon is a simple cutlass/sabre though. Oichi uses a Kendama (child's puzzle toy) in her first appearances, but from the third game on, she switches to a bunch of barbed chakrams. Shingen Takeda uses a fan. That one did actually occur historically, although only once, in a single incident.
** Oichi's case is explained in the interlude, where it clearly states she took ahold of the first thing she could find to use as a weapon. And her weapon behaves like a MACE.
* IntercontinuityCrossover:
** Before there was ''VideoGame/FireEmblemWarriors'', before there was ''VideoGame/HyruleWarriors'', Koei's collaborations with Creator/{{Nintendo}} began in the original release of ''Samurai Warriors 3'' with a game mode based on the NES game ''VideoGame/NazoNoMurasamejo'' and its protagonist Takamaru as an unlockable GuestFighter.
** ''VideoGame/PokemonConquest'', in the sense that the character designs for the Warlord cast -- Nobunaga, Oichi, Mitsuhide, Shingen, Kenshin, etc. -- are all lifted directly from ''Samurai Warriors 3''.
* KatanasAreJustBetter: Surprisingly few characters use a katana, actually, but those who do wield them to great effect.
* KeyStoneArmy: Scripted twists (such as body doubles and dramatic entrances) aside, as soon as the commander of the opposing force retreats clutching his side/keels over dramatically, the rest of his army beats it regardless of numbers. Of course, with how many of them you were likely cutting down before defeating the commander, it's amazing they wait that long to get out of your sight.
** On a smaller scale, the defeat of an officer or captain prompts most of enemies around them to flee unless the difficulty is set on Chaos.
* TheLastOfTheseIsNotLikeTheOthers: In ''4'', since the story mode is now faction-specific rather than character-specific, they give more focus to the development of the clan while CharacterDevelopment only occasionally appears. Except for Sanada. Notably, it's the ''only'' story mode that gives more focus to the relationship between Sanada brothers and few other characters like Ina, Keiji, Kanetsugu, and Mitsunari. The development of Sanada clan in the story is only vaguely referenced in the narrative.
* LimitBreak: In ''4'', using a Musou Attack while Rage is active results in the devastating Musou Frenzy.
* LeeroyJenkins:
** If you're not the one Leeroy-ing into the crowd, expect one or more of the AI-controlled officers to charge recklessly and then necessitate you bailing them out. There are even a few stages that ''penalize'' you for getting ahead of yourself. ''Chronicles'' has several missions that are only accessible through doing this, such as the mission to kill Asakura at the start of Kanegasaki (once he starts marching, killing him is the only requirement to complete the scenario, not any specific objective).
** And a very unusual case of the game forcing you into one: at the end of Yukimura's story mode, he decides the final battle a lost cause, the game invalidates the defeat conditions and declares everyone but you expendable, a path straight to the enemy camp (but swimming in enemy soldiers) opens up, and in [=SW3=] your items are disabled. Why push you down the road of a totally reckless charge? Because historically, ''he actually did that''.
** Nagamasa Azai, Battle of Anegawa. Even if he is exhausted, he will continue pressing the attack until he is forced to retreat or he forces nobunaga Oda to retreat.
--> '''Nagamasa Azai''': ''"This is it. This will be my final attack!"''
** Nene's Dream, Melee at Sekigahara. even with Okuni and Hideaki Kobayakawa on your side, you STILL end up doing most of the fighting.
* LoadsAndLoadsOfCharacters: As of ''Spirit of Sanada'', there are 61 characters who are playable. If you include the important [=NPCs=] with unique character designs, the count would triple.
* LongLived: Given the [[CrapsackWorld state of the era]], some characters rather extraordinarily manage to hold themselves together for the entire Sengoku period, either because they historically did so or because they're made as one. Probably the most remarkable is Tokugawa Ieyasu, who has been present since the Imagawa's disastrous defeat at the hands of Nobunaga at Okehazama (1560) all the way to the Osaka Castle siege, 55 years later. Remarkable because Ieyasu is depicted as a middle-aged man since Okehazama, when he's only 17 at that time. Same with Munenori and Koshosho, who are both introduced as Nobunaga's adversaries during his conquest of the capital in the 1560s and are still going strong by time of the Osaka Castle campaign, but that's because Munenori is [[CompositeCharacter combined with his father Muneyoshi]], while Koshosho is mostly a fictional figure to represent the entire Miyoshi clan.
* LoveAcrossBattlelines: Oichi and Nagamasa in some scenarios.
* MoraleMechanic: The series eats and breathes morale. Morale determines who wins the battles when you're not in the area, and can make enemies harder to fight if they have a lot of it. You can reduce overall enemy morale and raise your own by killing troops, defeating enemies, and activating (or preventing) certain events. To take it even farther, individual troops have their own morale. Killing a troops leader causes him to run off. Defeating an officer has the potential of making everyone run.
* MoodWhiplash: Two immediate cutscenes post-Odawara in ''4''. First cutscene has Lady Hayakawa and Kai mourning Ujiyasu's death. Second cutscene has... Hideyoshi celebrating his achievement in uniting Japan by throwing a lavish picnic, complete with silly dancing.
* MookChivalry: Besides stat boosts to enemies: the intensity of this factor is what differentiates the various difficulty levels the most: on Easy groups of enemy soldiers will barely attack you for scratch damage and flee if you so much as look at them. in Chaos mode, not only do all of them rush you, but they can stagger you even when outside of the Power Zone.
* MookMaker: Strongholds serve this function, providing reinforcement troops to whoever holds them. They change hands whenever the other side kills the Guard Captain unit defending them.
* MovingTheGoalposts:
** Tachibana (of all people) pulls this on you in the third-to-last normal mission in ''katana''. Never mind that the part up to it is a bit of a GuideDangIt as to how you're supposed to strafe, no, she wants you to defeat 30-ish enemies [[FakeDifficulty without any attack successfully landing on you.]] The enemies do include [[GoddamnBats Kunai-throwing ninjas]]. Fortunately, she doesn't make you fight her without taking damage, saving it from becoming ThatOneLevel.
** More generally, this will sometimes happen in the main games, where you defeat the enemy commander only for reinforcements to arrive at that very moment and the stage's goal change to defeating ''their'' leader.
* {{Multishot}}: Several characters have this capacity, such as Motonari Mori with his wrist-mounted crossbow.
* NameOrderConfusion: For some reason, the localized versions of the games use the Western name order (given name first, family name last), despite the game taking place BEFORE the Meiji Restoration. This is particularly jarring in the entries that aren't dubbed, as the way the name is presented in the dialogue box contradicts the voice track.
* NeverASelfMadeWoman: [[JustifiedTrope Justified]] as it's (mostly) based on historical events in 1500s Japan. Compared to ''Dynasty Warriors'' however, ''SW'' is more progressive regarding its treatment of women; even if they appear because of their connections to men, they still have individual goals to follow on and aren't overly clingy to their spouses. Then again, no matter the place, values of the 16th century are very different from the 3rd century.
* {{Ninja}}: Kunoichi, Hanzo, Kotaro, and Nene. There are also ninja mooks. As of ''4'', there are even officers with "Ninja Master" model and armed with Ninjato and have Ninjato movesets, usually from Sanada (alluding Sanada Ten Braves) or Hojo (alluding Fuuma Clan). In ''Spirit of Sanada'', Sanada Clan has ''three'' officers with NonStandardCharacterDesign who story-wise are ninja and gameplay-wise are armed with Ninjato and have Ninjato movesets. Even better: one of these three characters is a ''BadassGrandpa'' Ninja! And of course, not to forget Sasuke who made his debut here.
* NonStandardCharacterDesign: As of ''4'', there are many generics with unique design, usually they are daimyo or important characters in history. Even Hideyori, who has exactly one appearance (Osaka Campaign) also got unique character design. In ''Spirit of Sanada'', '''[[UpToEleven plenty]]''' of generics under Sanada, Takeda, and Toyotomi have unique design; to the point that the only thing that make them generics is their katana/spear/ninjato moveset. There are also few generics with unique design outside these three clans.
* OffModel: A custom warrior using a moveset with a unique mounting animation can result in very obvious clipping into a horse's back if the models are of different size.
* OldSaveBonus: If you start playing ''Samurai Warriors 2'' on the UsefulNotes/Playstation2 and have save data from the first game, it'll let you choose to start with Hanzo and Kenshin Uesugi unlocked and Tadakatsu Honda with save data from Xtreme Legends.
* ThePowerOfFriendship: Naoe Kanetsugu goes on at length about it. Several characters tell him to shut up.
* PowerUpMotif: In ''4'', when you use Ultimate Musou (a musou attack you use while you're in "Musou Gokui" or "Rage Attack" state), there's an audio motif that very briefly overrides the current stage's theme music for several seconds.
* PreAssKickingOneLiner: As standard for a ''Warriors'' game, used for full effect during [[CallingYourAttacks True Musou attacks]].
* PrettyInMink: Some of the clothing options (at least for original characters) include a cape and hat trimmed with white fur.
* PunnyName: Non-comedic example, as well as a meta example. The Japanese title "Sengoku Musou" is a pun on "Sangoku Musou", the Japanese name of the ''VideoGame/DynastyWarriors'' series.[[note]]Which was named "Shin Sangoku Musou" beginning with the second game ("Sangoku" refers to the China's [[ThreeKingdomsShuWeiWu "Three Kingdoms"]] period, hence "Sangokushi", or "Literature/RomanceOfTheThreeKingdoms").[[/note]]
* RedshirtArmy: Pretty much who you fight save for the occasional officers, most of which end up as merely EliteMooks at best.
* RelationshipValues: In the ''Chronicles'' games and Chronicle Mode of ''4'', you grow closer to the various characters as you fight alongside them and view their relationship events.
* {{Sarashi}}: [=SW3=] provides this in the form of the female Create a Warrior model who can have half a kimono top and a sarashi.
* ScaryImpracticalArmor: A staple somewhat given this is common with the Warriors series in general. Naomasa Ii in ''Samurai Warriors 4-II'' is notable in that, while his helmet contains ''very'' tall and impractical vertical spires, said spires are ''less'' ridiculous than most depictions of his helmet.
* ScrewThisImOutOfHere: Many battles will have this occur when it turns against one side and the commander decides it's time to retreat. Once you beat the enemy commander, all remaining generic characters on that side will immediately panic and run for the nearest spawn area.
* SerratedBladeOfPain: Ginchiyo Tachibana. All her weapons are barbed katana with a lightning motif.
* ShoutOut: In the first game, Mitsuhide is ambushed in his first path's penultimate level, Yamazaki, by a raid of peasant warriors seeking to avenge Nobunaga's murder; killing them fulfills an objective. The real-life Mitsuhide's generally accepted cause of death was being slain by a peasant warrior in the same battle.
* ShroudedInMyth: Meta-wise, this seems to be occassional problem with story-telling in ''Samurai Warriors'' games. Unlike ''Dynasty Warriors'' that has ''Literature/RomanceOfTheThreeKingdoms'' and more historically-accurate ''Records of the Three Kingdoms'' as material sources, ''Samurai Warriors'' has very few historical informations as material sources, so Koei has to improvise a lot for many characters' story mode. On the flipside, this allows them many more leeways in depicting the period, since, without any authoritative accounts to keep track with, fewer criticisms can be thrown from purists regarding significant changes.
* StatGrinding: In addition to the standard experience-based leveling system, ''4'' gives each character proficiency ranks in normal attacks, power attacks, hyper attacks, and special skills that rise as the character performs the actions in question and increase their effectiveness.
* StealthPun: While present since the series started, one of the loading screens for ''Spirit of Sanada'' points out that defeated enemy ninjas will sometimes drop [[Anime/NinjaScroll scrolls]].
* StraightForTheCommander: Frequently a viable means of finishing a scenario immediately. In ''Chronicles'' it's the only practical means of getting all friendship events due to the sheer number of them available.
* StockNinjaWeaponry: Hanzo wields a Kusarigama in battle. Other ninjas include Kunoichi and Nene (daggers) and Kotaro Fuuma (clawed gauntlets).
* SuperMode: Rage mode in ''4'' gives the user a huge power boost and makes them completely invincible for the duration of the effect, at the cost of the entire Spirit Gauge.
* SuperMovePortraitAttack: ''3'' features cut-in portraits for characters using True Musou attacks. ''4'' features more traditional zoom-ins for Musou and True Musou attacks while reserving the cut-in portraits for activating Rage Mode.
* SwordAndGun: After ''1'', [[UsefulNotes/DateMasamune Masamune Date]] uses a pair of flintlock pistols in conjunction with a cutlass. In addition, the male player character in the ''Chronicles'' games uses a large katana in conjunction with a rifle. This moveset was carried over into ''4'' as one of the default weapons for custom characters.
* ThemeMusicPowerUp:
** Tadakatsu, following in [[VideoGame/DynastyWarriors Lu Bu]]'s tradition.
** That specific example aside, it's also common throughout the series for a TriumphantReprise to kick in when victory is near.
* UnexpectedGameplayChange:
** Some requests in Survival Mode contain stealth missions. Also, Sugoroku.
** Magoichi occasionally has sniping missions.
** Cannoneering sub-missions in the third game.
* VariableMix: Several stages in ''4'' have music that seamlessly fades from a low-key version to the full song and vice-versa. The game also features filters that are used according to the status of the player (Ex.: A low-pass at low health).
* VeryLooselyBasedOnATrueStory: This fluctuates with each game, but it keeps certain points very much intact - namely the deaths of Nobunaga, Mitsuhide, and Hideyoshi are always kept at when they're supposed to be, unless you're playing as them.
* VirtualPaperDoll: Most games in the series allow the player to make their own custom Edit Characters. The options for them are rather restricted until [=SW4=], which uses a similar character creation system to ''VideoGame/DynastyWarriors 7 Empires'', allowing players great control over the appearance of their characters and choice of whichever weapon they want (except for Kotaro's gauntlets).
* WeaponizedBall: Oichi has her EpicFlail kendama, Kanbei's {{Energy Ball}}s, and Yoshimoto's kemari ball.
* WeCannotGoOnWithoutYou: Even though the loss condition in many stages is stated to be the defeat of another allied commander than yours, you also lose the battle if your own player character loses all their health. Justified for most of the series, since emptying your health bar is a standard for defeat and you make the most impact in a battle. However, this is played somewhat straight in ''4'' and ''4-II'', as you can use two playable characters instead of just one and lose automatically when only one of them loses all of their health, even if defeated units generally retreat rather than die.
* WhatIf:
** Most of the characters in the first game had a path like this, with a few having pretty much their entire scenario going this way, especially characters who weren't historically significant warriors like Ishikawa Goemon or Okuni.
** ''Chronicles 3'''s story will branch into hypothetical scenarios if certain conditions are met, such as "What if Yoshimoto survived the Battle of Okehazama?", or "What if Shingen didn't die on the way to the capital?"
* WorldOfBadass: [[VideoGame/DynastyWarriors Par for the course]] for a Koei game.
* {{Xenafication}}: Like the parent series, female figures who generally stayed in the background in history are made to {{Action Girl}}s. However, it's slightly excused in this series since the women, while not active officers, were documented to have received self-defense skills befitting noble ladies, mostly so they could save themselves should enemies capture them. It's also averted in the case of Tachibana Ginchiyo and Ii Naotora, who actually ''did'' become military leaders of their respective clans, even if they did not participate in any significant battles.
* YouALLLookFamiliar: There are hundreds of generic NPC officers with nothing but names to differentiate them.
