''Faxanadu'' is a 1987 SideView ActionAdventure RolePlayingGame for the [[UsefulNotes/NintendoEntertainmentSystem NES and Famicom]]. It is considered a [[GaidenGame side story]] for the ''VideoGame/DragonSlayer'' series of videogames and is actually a port/spinoff of the {{PC88}} game ''DragonSlayerIIXanadu'' (''Faxanadu'' being a portmanteau name of ''UsefulNotes/{{Famicom}} Xanadu'').

The game features the adventure of a nameless elf who returns to his home town of [[AllThereInTheManual Eolis]] to find it depopulated and overrun by monsters. After a visit to the local church and the King, the hero [[ButThouMust is tasked by the King]] to infiltrate the "WorldTree" and awaken three springs of pure water. Afterwards, TheHero is sent to the higher branches of the World Tree to locate and defeat the Evil One, the hideous monster responsible for the invasion of the towns.

The hero can equip different types of items: weapons, armor, shield, and miscellaneous that can be used directly in the overworld map. He can learn magic as well, and use different spells with different attributes and effects to attack enemies.

! This game contains examples of:

* AdamSmithHatesYourGuts: Prices increase as you progress along the game. The town of Conflate, for example, has meat more expensive than full healing earlier in the game.
* AlienInvasion: The Evil One is heavily implied to be an alien who came to the world on a "meteorite" and is corrupting the Dwarves to do his bidding. He even looks like another famous Franchise/{{Alien}}.
* AllThereInTheManual: The structure of the overworld, as well as the nature of the Evil One, are only barely hinted in the game but far better explained in the game manual's imagery.
* AmbidextrousSprite
* BigBad: The ''Evil One''.
** TheDragon: A literal one - the ''King of Dwarves'' was turned into a dragon-like creature.
* ChainReactionDestruction: Bosses like to go down with that manner.
* DiscOneNuke: The ''Magic Shield'' (the second strongest shield in the game) or the aptly named '''Death''' spell (about eight times as powerful as the basic spell) can be acquired as early as the second town. This can be accessed by patient cash farming, or backtracking with the mattock.
* DoomedHometown: The starting town is the player's hometown; by the time the game begins the town is already "overrun by monsters" according to the ''first'' encountered NPC who [[TheEndIsNigh goes on to announce that "the end is near"]].
* DummiedOut: A "lamp" item, a "book" item, and other items [[ShoutOut referencing the original]] ''[[DragonSlayerIIXanadu Xanadu]]'', were dummied out from the final game. As their script routines are reserved but left blank, some ROM Hacks exist that actually reintegrate these items to the gameplay with new effects.
* ElvesVsDwarves: If only because the Evil One turned the Dwarves into psychotic monsters. This is actually discussed at some point early in the game.
* FightInTheNude: Averted. Equipping different armour changes the character sprite.
* FlipScreenScrolling
* InterfaceScrew: One boss enemy is faced in a room that only exists for this purpose. It is possible to accidentally exit the room if you try to cast spells while standing next to the door.
* InvincibilityPowerUp: "[[http://i.imgur.com/3bzrr.jpg I am free from injury because of the Ointment!]]". Probably due to a bug, it prevented magic damage ''only when the player had NOT equipped a Shield''. It was still possible to bypass this limitation by flinging the sword at the right moment.
* MeaningfulName: The tower mazes, which feature names such as the ''Tower of Suffer''.
* {{Metroidvania}}: A world map considered in-game to be of ''gigantic'' proportions comprised by the town of Eolis, the WorldTree and the Fortress of the Evil One.
* MonsterTown: Below one of the towers are a set of houses inhabited by enemies; a nearby somewhat hidden NPC reveals it used to be part of the nearby town.
* NoSmoking: Curiously averted, given Nintendo's otherwise iron-fisted censorship. Several NPC characters can be seen smoking in the towns you visit.
* NotCompletelyUseless: the Hour Glass, a time-freezing item which caused some minor glitches in some parts of the game, is particularly useful against the Final Boss: it prevents him from ''firing projectiles''.
** It does the same against the Dwarf King Dragon Boss too! Since there is an Hour Glass spawn in the dungeon you find him in, one could argue that this mechanic might be ''intended''. The bosses might be immune to the magic, but their projectiles aren't. The last town also sells Hour Glasses, and items are usually only found/sold where they are meant to be used.
* OurDwarvesAreDifferent: In this game, they are ''eight-foot-tall gargoyles.''
* PoisonMushroom: The overworld sprites for useful ''Potion'' and damaging ''Poison'' are much alike (see also RealIsBrown), causing some players to mistake one for the other and take a fatal poison in a moment when they are low of health.
* PowerupLetdown: Due to a programming error, the optional [[spoiler:Pendant]], which the hero ''can'' acquire in a BonusDungeon during a SideQuest, [[spoiler:lowers attack power instead of raising it]].
* RealIsBrown: The games uses a particularly vivid color palette with an abundance of brown and red tints, especially in the upper branches of the World Tree. This gives the game a more realistic aura than some other games around its time. In contrast, the base of the World Tree uses a greener palette. As an unfortunate side effect, the browner palette makes it difficult to distinguish some [[PoisonMushroom items]] and enemies at certain screens during the second part of the game.
** Justified since the World Tree is withering. The final scene shows it restored and green.
* SavePoint: The churches are a variation of save systems, as they give you a password, called a "''mantra''". The mantra depends on the player experience and stores the inventory, golds and the location of the furthest church the player has visited, which is the point the player is returned to when he continues.
* SwordOfPlotAdvancement: The Dragon Slayer must be activated after the other parts of the mythical suits are collected for the last Guru to enable access to the final dungeons.
* ThemeNaming: the different types of keys are named and ''shaped'' after the "letter cards" (J)ack, (Jo)ker, (Q)ueen, (K)ing and (A)ce.
* WorldTree: The setting of the majority of the game (actually, only the starting town and the FinalDungeon are not part of it).
