->''YOU ZAP TO...''

''VideoGame/TheTowerOfDruaga'' is a 1984 arcade game released by [[Creator/NamcoBandai Namco]], about a knight named Gilgamesh (or "Gil" for short) who has to climb a monster-infested tower in order to defeat the demon Druaga and rescue Ki (pronounced "Kai"), a shrine maiden in service to the goddess Ishtar. It is infamous as the high-water mark of [[http://strategywiki.org/wiki/The_Tower_of_Druaga player-directed cruelty]] in videogames -- the acme of the old school style where videogames existed to challenge and defeat the player.

Each floor of the tower has a hidden treasure for the player to discover; some of these treasures, such as the Blue Crystal Rod, are essential to completing the game. The game, however, [[GuideDangIt offers no hints]] on how to find these treasures, which depending on the floor might involve anything from killing enemies in a certain order to walking over one or more points in the maze to crossing paths with a certain enemy to entering a special code to none or several of the above. The final floors with Druaga, Ishtar and Ki are especially tricky because certain missteps can cause Gilgamesh to be ZAPPED back to a lower floor.

The game spawned an irregularly released series of games, known as the "Babylonian Castle Saga":
* ''The Return of Ishtar'' (1986), an ImmediateSequel where Gil and Ki team up
* ''VideoGame/{{The Quest of Ki}}'' (1988), a PuzzlePlatformer prequel starring Ki
* ''The Blue Crystal Rod'' (1994), sequel to ''The Return of Ishtar'' again starring Gil and Ki
* ''Seme COM Dungeon: Drururuaga'' (2000), DistantSequel with [[CardBattleGame card-based gameplay]]
* ''The Nightmare of Druaga'' (2004), part of Chunsoft's ''Fushigi no Dungeon'' {{Roguelike}} franchise
* ''Druaga Online: The Story of Aon'' (2005), non-canonical four-player arcade game
* ''The Tower of Druaga: The Recovery of BABYLIM'' (2009), a [[MassivelyMultiplayerOnlineRolePlayingGame MMORPG]]

The first three games of the above list, as well as the [[VideoGameRemake remake]] of ''The Tower of Druaga'' for the PCEngine, were developed by Game Studio, the company founded in 1985 by Masanobu Endoh, creator of the original game.

Various {{Shout Out}}s and {{Bonus Dungeon}}s based on the game can be found in the TalesSeries and SoulSeries, and ''BatenKaitos'' has a {{Homage}} level that calls back to this game.

In 2008, the game was adapted into an [[Anime/TheTowerOfDruaga anime series]], with its first season being titled ''Tower of Druaga: The Aegis of Uruk'' and the second season in 2009, with the new subtitle "Sword of Uruk".

!! This video game series provides examples of:

* BlobMonster: Slimes in several colors.
* ContinuingIsPainful: Getting zapped to a lower floor destroys the highest-tier weapon and armor pieces, making the final boss fight unwinnable.
* TheDragon: Quox.
* DungeonBypass: The pickaxes, which break walls. The gold one has infinite uses, and makes the game considerably easier ("easy" being a relative term here...)
* EvilTowerOfOminousness
* GodGuise: Succubus on Floor 57 disguises herself as the goddess Ishtar. Killing her is one of the requirements for the Ruby Mace.
** In the PC Engine version, you do not kill her, and she gives you the Blue Crystal Rod instead.
* GuideDangIt: In each level of the game, there is a treasure which requires a unique and unguessable action. Even after working this out, some of the items are actually harmful. Avoiding the treasure isn't an option, either, as some are needed to complete the game.
* InfinityPlusOneSword: The Excalibur/Hyper Sword.
* InvincibleMinorMinion: Will O'Wisps.
* LockedDoor: You have to find the key to open the exit to the level.
* LostForever: The treasures under Guide Dang It. Uh oh...
* MissingSecret: Some levels don't even have a treasure.
** One port has a secret whose trigger is "exit the level".
* NintendoHard: Almost sadistically so for an arcade game.
* OneHitPointWonder: You have a HitPoints value, but you can't actually see it. It's also only used for fighting enemy Knights; slimes, magic spells, and whisps all use OneHitPointWonder logic.
* PoisonMushroom: The Potions of Energy Drain and Potions of Death, and any item after not obtaining the Balance on the previous level.
* PowerUpLetdown: Most of the weapon and armor upgrades don't actually do anything useful, but are necessary to eventually trade up to the highest-tier equipment, which is mandatory for the final battles.
* SaveThePrincess: Ki, though a shrine maiden and not actually a "princess" per se.
* SprintShoes: Jet Boots.
* StalkedByTheBell
* TakenForGranite: Ki, cursed by Druaga and turned to stone.
* TimedMission
* TrialAndErrorGameplay: The first game is possibly the most extreme example in the history of video games. The steps for acquiring the items on each level are so hilariously non-intuitive that one could be forgiven for labeling it an UnwinnableJokeGame.
* UnwinnableByDesign: Let us count the ways...
** Picking up the Evil Gauntlet permanently prevents you from drawing your sword.
** If you don't pick up floor 34's treasure, the next floor's key will not appear.
** Finally, after spending EleventyZillion quarters, you've reached the top of the tower and are ready to face Druaga in a climactic... Blue crystal rod? ''What'' blue crystal rod?!
* VideogameCrueltyPunishment: You can attack Ishtar and Ki instead of rescuing them... if you don't mind being sent back almost to ''the beginning of the game''.
