[[caption-width-right:350:One Ninja Vs. An Entire City]]

Creator/FromSoftware's attempt at making a ''VideoGame/NinjaGaiden'' [[FollowTheLeader killer]] on the Xbox 360.

In [[TwentyMinutesIntoTheFuture 2015]] an infestation of mutagenic parasites develop in [[TokyoIsTheCenterOfTheUniverse Tokyo]]. A special group of international operatives was called in to stop them, but only one survived without being killed or infected. You play as the sole-surviving member of the team and ninja, Ken Ogawa, fighting off the hordes of strange mutants infesting Tokyo with the help of group director, Agent Michael Wilson. It features many over-the-top elements and is generally quite fun to play, but was overshadowed by most other releases at the time.

!!Tropes used in ''Ninja Blade'':
* ActionCommands: The game took a critical drubbing because of its over-reliance of Quick Time Events to do ''anything''; jumping out of windows, killing bosses, ''walking down a hallway,'' etc.
** It also has [[AntiFrustrationFeature Anti-Frustration Features]] specifically for the [=QTEs=]. First, the player can adjust the difficulty of them independently of the combat difficulty. Secondly, the longer [=QTEs=] have sequences inside them, so if you fail a command, you just go back to the beginning of the current sequence.
* AlwaysSecondBest: The reason Kuroh Sakamoto let himself be infected was because he always felt inferior to Ken and wanted to use the parasites to surpass him.
* ArrogantKungFuGuy: Kuroh Sakamoto...who, unsurprisingly, turns out to be evil by the end of the first chapter.
* BadassNormal: [[spoiler: Michael Wilson, Senior]]
* BlackDudeDiesFirst: African-American ninja Andy is the first named character to die.
* BladeRun: Used in conjunction with a NinjaRun to trigger the finishing move on the second to last boss.
* {{BFS}}: The Stonerender Sword and [[spoiler:Moonlight Sword]]
* ButNotTooForeign: Ken Ogawa is half-Japanese, half-American. It's also reflected in his name.
* CosmeticAward: Including a [[TechnicolorNinjas clown suit]].
* CoupDeGraceCutscene: Every time you deplete a boss's life meter.
* CutAndPasteEnvironments: Mission 7.
* DidYouJustPunchOutCthulhu: It took some help from having special blood, and [[spoiler: an ArchnemesisDad who was FightingFromTheInside all along]], but Ken Ogawa ends up slaying the core consciousness of the parasites.
* EmpoweredBadassNormal: Both Kanbe Ogawa and Kuroh Sakamoto are incredibly powerful humans that owe their abilities to their mastery of certain SupernaturalMartialArts. Once infected by the parasites, they both become even more powerful. Moreso in the case of Kanbe whose physical and mystic abilities are amplified to ludicrous levels.
* FaceHeelTurn: Kuroh Sakamoto and Kanbe Ogawa--[[TheRival Ken's rival]] and [[ArchnemesisDad father,]] respectively--in the ''first damn chapter.''
** GoodAllAlong: Later, however, it turns out that [[spoiler: Kanbe Ogawa ''deliberately'' allowed himself to be infected in order to find the core of the parasitic consciousness.]]
* FanDisservice: Three words: tentacle monster panties.
* FieldOfBlades: Where you fight the FinalBoss. It doubles as a BattleInTheCenterOfTheMind.
* GiantEnemyCrab
* GiantSpider: The second boss, Arachne.
* GottaCatchThemAll: The Shinobi Moji.
* HighlyVisibleNinja: Well, riding a Striker on live TV sure qualifies, if crushing giant spiders with a demolition ball or stopping a crashing plane only with bare hands wasn't enough.
* KatanasAreJustBetter: The Ninja Blade, obviously.
* LargeHam: Any infected character that speaks takes this one UpToEleven.
* MythologyGag: One of the secret weapons you can unlock after finding all 8 Shinobi Moji is [[spoiler:The Moonlight Sword, which has appeared in nearly ''every'' single From Software game since its debut in ''King's Field'' (including the ''Armored Core'' games, where it was a laser blade instead of a normal sword.)]]
** Also, from the manual, Special Agent Michael Wilson is the father of the President from ''Videogame/MetalWolfChaos''.
* {{Ninja}}: ''Duh''
** NinjaRun: Once again, ''duh.''
* NotTheFallThatKillsYou: Apparently, true ninja don't even need ''parachutes'' when diving out of a plane.
* PressXToNotDie: One-third of the game, approximately.
* PuppeteerParasite: The mutants and other infectoids are all created from hookworms infesting humans...and, in some cases, even ''machinery,'' as the Slime Chopper demonstrates.
* RuleOfCool: Riding a missile shot by a mutant-infested helicopter ''right back at it,'' leaping hundreds of stories in the air only to harmlessly land because of some improbable acrobatics, fighting giant worms the size of skyscrapers...and the list just keeps going on.
* ShooOutTheClowns: After Andy dies in the intro, the entire game becomes increasingly dark.
* SuperSoldier: Ken's special blood and abilities were stated by Kuroh to be the result of genetic engineering and laboratory experimentation since before his birth. It's never confirmed if he was lying.
* TakingYouWithMe: Kuroh Sakamoto, to Ken after their duel courtesy of [[ActionBomb a bomb in his gut.]] It doesn't work, as Ken leaps clear before the explosion.
* TokenMinority: Andy Walker, the African-American man of the team.
* TokyoIsTheCenterOfTheUniverse: This whole mess takes place in Tokyo, and a big deal is made out of how catastrophic it would be if it had to be nuked to stop the parasitic outbreak.
* TheTokyoFireball: in the bad ending.
* WallJump
* ZombieApocalypse: The parasitic worms that infect humans invoke this...
** OurZombiesAreDifferent: ...only with the sorts of freakish mutations you'd find in the more dangerous creatures from the ''VideoGame/ResidentEvil'' series.
