Dracula 3: The Path of the Dragon is a 2008 point-and-click adventure video game developed by Kheops Studio for Microsoft Windows, and published by MC2 France under their Microïds label in Europe and Encore in North America. In 2010, an abridged version of the game developed by Tetraedge Games and published by Chillingo was released in a three-part episodic form for iOS (as Dracula: The Path of the Dragon). The full version of the game was ported to OS X in 2010, published by Coladia. Also in 2010, the three-part iOS version was made available for PC as the Dracula Series. In 2014, the abridged iOS version was made available as a single game on Steam.

The game follows 1999's Dracula: Resurrection and Dracula: The Last Sanctuary, although the storyline is unrelated to either game. Path of the Dragon takes place in 1920, and follows Father Arno Moriani of the Sacred Congregation of Rites, who is sent to the village of Vladoviste in the diocese of Alba Iula in Transylvania to investigate the possible canonization of a recently deceased doctor, Martha Calugarul. However, Moriani soon learns Calugarul believed herself to have been engaged in a battle with a vampire, possibly Dracula himself, and although initially skeptical of the story, he slowly comes to believe there may be some validity to it. A loose sequel to Path of the Dragon was released in a two-part form in 2013; Dracula 4: The Shadow of the Dragon and Dracula 5: The Blood Legacy.

Path of the Dragon was most widely reviewed for the PC, where it received mixed reviews. Most critics praised the graphics, music, sound effects and voice acting, but the gameplay and puzzles received a more mixed response, with some finding the puzzles too esoteric and/or illogical, and others feeling they fit the nature of the game well.

Path of the Dragon is a first-person point-and-click adventure game, which employs an "empty" HUD; the player's inventory is accessible through a button press, which also allows access to a list of objectives, details of all conversations, records of all documents seen and collected, and options for the player to save their game, quit their game, or load a previously saved game. As such, the entire screen depicts only direct gameplay.

The game uses a basic point-and-click interface to move the player around and manipulate the game world. Within each screen, the player is free to look around 360 degrees. As the player moves the cursor around the screen it can change into different styles depending on the situation; neutral cursor (no interaction is possible), an arrow (the player can move in the direction indicated), a mouth (the player can speak to the character over whom the option appears), an eye (an area or object can be examined in more detail), a magnifying glass (an object contains important information which needs closer examination), a hand (the player can take the object), a cog (the player must use an inventory item to initiate interaction with the object), a cog with red line (the player is attempting to use the wrong inventory item to initiate interaction), a left-right horizontal arrow (the object can be moved left and right), an up-down vertical arrow (the object can be moved up and down), a circular arrow (the object can be rotated).

When the player clicks on a person to whom they wish to speak, a list of conversation topics appear on screen. When the player picks up an item, it is automatically put into an auto-holder rather than the main inventory, and must be transferred manually from the auto-holder to the inventory screen. This allows the player to sort the inventory in any way they wish. A major part of the gameplay is examining documents, which have a separate section in the inventory screen, presenting the player with numerous options. For example, the player can organise the documents in two ways; by title or by the order in which they were found. Players can also "flag" documents so as to relate them to particular clues, and can then examine all documents related to any one particular clue together, without having to navigate through non-related documents. The documents screen also includes a "compare" view for examining different copies of the same pictures to find differences between them, and all documents can be examined in more detail with a magnifying glass. The game also includes complete copies of the Bible and Bram Stoker's Dracula, and each text has a "random page" option, which opens the book at a random passage. If done at certain times in the game, the random option can present clues to the player as to how to proceed (when this is the case, the "random page" option flashes).

The 2010 three-part abridged iOS version, which was also released for Windows as the Dracula Series, adds several new features to the game, such as an optional help feature (which highlights interactive zones on each screen), and a "quick inventory" (which allows the player to hold one item and access it without having to enter the inventory screen). This version of the game also removes several of the more difficult puzzles and is shorter than the main version of the game, with several cutscenes and plot points absent.

The game begins in 1920, with Cardinal Felicio Briganti sending Father Arno Moriani of the Sacred Congregation of Rites to the village of Vladoviste in the diocese of Alba Iula in Transylvania to investigate a candidate for sainthood; Martha Calugarul, a physician and scientist who died several months previously. The process is being fast-tracked because Transylvania has recently been annexed by Romania, leaving Catholics in the minority, and the church feels a local saint may help the Catholics reaffirm their identity in relation to the majority Orthodox in the diocese.
