Ao Oni Plus

is a fan-made extension of the original Ao Oni (Ver 6.23). This unofficial extension provides new additional content to the game in many different forms. The most notable of which is the ability to play as different characters aside from Hiroshi. The extension also includes the potential for new outcomes to the story of each character, new Onis within the mansion, new cheat codes for various characters, and among many other new features. The game is currently in a Beta form (Ver 0.4), and the only new character who can be currently selected is Mika. Later in 2016, the project was then carried by one user. Now the game is currently in a finished form (not completed) (Ver 0.5), and you can play as Takuro or Mika.

PlotEdit

WARNING: This page may contain spoilers or solutions to puzzles. Read further at your own risk!

The game begins the same way as it does in previous installments of Ao Oni (Version 3 and onwards). Hiroshi, Mika, Takuro, and Takeshi all travel to an abandoned mansion on the outskirts of their town. The characters talk among themselves within the foyer until the sound of a plate shattering is heard in the distance.


If the player has input Mika's or Takuro's name into the name select screen at the beginning of the game, then Mika or Takuro will investigate the noise of the plate falling, as opposed to Hiroshi. As such the player is then put in control of Mika or Takuro, and the story then progresses from her/his point of view. If any other normal code has been entered, or if the character's name was not changed, then Hiroshi will investigate the sound and the game proceeds as it normally would.

Mika's Story

MansionEdit

Playing as Mika will generally follows the same path as it did with hiroshi of Ao Oni Ver 6.23, but with minor changes elements along with new events added in.

After Mika encounters the Oni for the first time and later obtaining the screwdriver to unscrew the door knob, she would soon meet up with Takuro, which she becomes very hesitant to split-up when he suggests the idea of doing so in order to find a way out.

Later on, she obtains the Kid's Bedroom Key from the piano room safe box, she would soon meet up with Hiroshi. The player then is given a choice whether to team up with Hiroshi or continue alone without him. Picking one of those options will effect other events in the story.

After solving multiple puzzles and outrunning the Oni several times, Mika obtains the key to the basement. Before entering the basement, a loud bang or a thumb is suddenly heard from the floor above. Investigating the Kid's Bedroom on the 2nd floor turns out to be Squatto making the noise. This prompts into a chase with the Squatto in persuit.

Later, the player can enter the basement.

BasementEdit

Upon reach the Annex, the lighter she uses for runs out of fluid. It's here that Mika would obtain more fluid for it, albeit having to manuver around a very dangerous incarnation of the Oni to reach it: the Roach Oni, otherwise known as Leechum. After carefully avoiding the insectoid-type Oni and obtaining the lighter fluid, Mika soon meets up with Takeshi, who blames himself for the current situation they're in and runs off.


ChoicesEdit

Chose to team up with HiroshiEdit

The ladder will be seen intact and Mika, Hiroshi and Takeshi suggest this is the best way to escape. Mika initially protests however, stating that she doesn't want to leave Takuro behind. This prompts a search for him, with a clue from Takeshi stating that he was last seen searching through the Annex for a way out. The backdoor key will be on the ground.

Heading back and searching through the Annex, they will find him near where the Back Door is in one of the doll puzzle rooms. Talking with him allows the player to team-up with him, giving the player a full party. However, after Takuro joins and heading back to the roper ladder. The oni had already eaten it, prompting a chase scene. Later onwards, Mika and the others head to the Old Building.

New FeaturesEdit

With this extension comes various new changes and additions to portions of the game. Mainly in the form of new aspects for different game modes, changed factors for portions of the gameplay and story, as well as new cheat codes.

Some notably minor changes include changed dialogue for new story modes. An example of this is Mika's changed dialogue when encountering Takuro on the 3rd floor after being chased by the Oni for the first time. Another instance is the dialogue between Mika and Hiroshi, which prompts the potential option to either team up with him or continue alone. In the current version of the game, picking either option does not effect any major outcome of future events during the game. This will however, have a much greater impact in future releases.

Cheat CodesEdit

Another defining new aspect of the game are various new codes. These can be entered at the start of the game when asked to name the character.

Planned Additional ContentEdit

More additional content has been planned to be included into this extension with each update. Among other things, the list of currently planned out and new content that will most likely appear in updates of this extension are as follows:

Takeshi Mode: The ability to play as Takeshi. Currently playable, but has graphical and dialogue errors.

Prototype Mode: This mode would give Hiroshi and some other characters their proto-type appearance and names from Version 1.0 of Ao Oni. For example, Hiroshi's in-game appearance would be that of his original one in 1.0, and Mika's name would be changed to Megumi.

Naoki: The potential for the scene including Naoki and the 'Happy Birthday' scenario to make an appearance somewhere within the game. Naoki is also being considered as a standalone playable character at this point. Currently if entered just a scene of Naoki following the original 4 into the mansion. It is very buggy and unplayable for the most part, but interesting to see whats in store.

Mixed Mansion Mode: A mode which can be accessed upon completing the game a specific way. This gives you access to a code which puts you in a highly altered version of the game's maps, with some potential layouts similar to older versions of the game.

New Onis/Threats: Many other new Onis will be introduced into the game, as well as some potential unexpected new threats to hinder the player.

Secret AreaEdit

Warning: This next section contains spoilers and the solution to finding the Secret Area

Announced when the Demo 0.4 version of the game was released, a secret area was included somewhere in the game. Players are presented with three new items called 'Hint Cards' which are found through-out different portions of the game.

Hint Card 1 can be found in the Library of the first floor, somewhat out of view if players immediately attempt to grab the Bedroom Key when they first enter this room. Given this, this Hint Card is somewhat easy to overlook. Hint Card 2 can be found on the bed in the dimly lit room of the Annex's second floor. Again, this is somewhat easy to overlook, considering the low light source in this room, as well as the Hint Card being the same color as the bed. Hint Card 3 can be found on a table in the Annex's Basement, specifically on a table to the left of the puzzle found in the room after using the Iron Gate Key.

When all three hint cards are obtained, they read the following messages. Hint Card 1: "5 + 5 = ?" Hint Card 2: "Sanctuary on the 3rd Floor" Hint Card 3: "Everything but the _______ sink."

When all three cryptic codes are pieced together, they will give the player a somewhat general idea of what needs to be done. First, the player must go to the cabinet on the third floor of the first part of the mansion. You must then enter and exit the cabinet a total of 10 times. After this is done, you must go downstairs to the first floor, primarily to the kitchen where you first find the plate shard. If you have done the previous step correctly, then inspecting a certain portion of the northern wall of the kitchen with the Action Button will cause a black door to appear with a sudden noise, as well as causing the screen to shake slightly. This door will lead you to the secret area: Dr. V's hidden research center.

The secret area has a few new sights for the player to view, along with some new content. The area itself is divided
Ao Oni Plus Secret Area

The main lobby of the Secret Area.

into a few specific sections: The Entrance, The Lobby, The Museum/Collection, and Model Swap Station. The Entrance is a simple, small area where the player first enters upon reaching the secret area. By reading the open notes on a nearby desk, the player learns that this hidden research center was created by Dr. V (the antagonist of Machina Oni, the game Ao Oni Plus was originally going to be). From here, the player can head to the Lobby, which in turn acts as an entrance-hub to the other two sections of the secret area. Notably, a west-wing/path leading to the left is visible, however it is currently 'under construction' according to Dr. V's notes.

Heading to the right will bring the player to Dr. V's collection/museum. This is an area which has displays of almost every incarnation of the Oni (save for Character Onis), along with brief descriptions of their characteristics written by Dr. V. Additionally, models of other Oni's from different fan-games make an appearance as well. Among them including: 'Steve' from Heta Oni, the Red Oni from Crom Oni, the White Oni from Siro Oni, the Bloody Oni from Hakyo Oni, the Cheshire Oni from Akame Oni, and a Rainbow/Multicolored Oni. Additionally, there is a spot where the player can pass through the wall in order to reach a hidden Oni display, one representing the Oni's appearance in the South Park joke-mode.

Heading north from the lobby will take the player to the Model Swap Station, which is home to several talking NPC Cats. The cats will give you helpful information here, such as how the Model Swap Station works, to various clues about the hidden Oni display and a hidden code. It's here that the player can swap their model for many different ones found through-out the game, ranging from other character models, to models of the Oni, and even to various inanimate objects. Similar to the Oni Collection room, there is also a spot here where the player can pass through the wall to reach a hidden model, that of Jimbo's from the South Park joke mode.

As stated, there is also a hidden code to be found within the Secret Area. Inspecting various objects such as bookshelves, desks, and plants will sometimes reveal brief messages containing one letter. Piecing all of these letters together and unscrambling the two letter word they form will give you the 'Meow Mix' code.

Original conceptsEdit

Originally, Ao Oni Plus was at one point going to be it's own standalone fan-game. Some of the working titles for this game included "Omega Oni," "Robo Oni," "Meka Oni," and "Bio Oni." Eventually, a final name was decided on in the form of 'Machina Oni.' Part of the title itself is derived from the phrase 'Deus Ex Machina' - which one of it's translations is known as 'Machine from God.'

Machina Oni was originally a standalone game with a plot only somewhat connected to the original Ao Oni. In it, the player would control a young woman by the name of Maria. The story would involve Maria attempting to investigate the source of a strange disturbance within her town, which would eventually lead her to a seemingly abandoned complex. It's here that she would discover many strange things before encountering a mechanical version of the Oni. As it turns out, someone has been attempting to secretly manufacture robotic versions of the creature for their own mysterious and twisted purposes. Maria would have to discover the identity of the mysterious antagonist behind this madness, 'Dr. V,' while evading his immitations of the Onis. As stated from a scrapped excerpt from a potential opening sequence/general backstory from the game:

"Maria S. Kenyetta, Age: 23, Gender: Female. You are the one who has set out to discover the source of the havock and fear that has plagued your home town. Random acts of violence have been popping up left and right, along with a series of grizzly murders. Fearing your close friends and family might suffer the same fate, you head out into the investigative field to put an end to this, before everything turns to ruin.

All signs from your countless investigation processes have lead you up to this. This seemingly abandoned complex is the source of what many describe as 'mechanical monsters' who are responsible for these attacks. Signs of human activity are somewhat prevelant, and further research has lead you to believe who is exactly responsible for the creation of these monstrosities. It's here that you'll enter inside and take down this opperation, along with it's loathsome overseer, Dr. V.

You will no doubt encounter many hostile threats on your journey. Dr. V's employees range from scientists to soldiers, all working against you in various ways. They won't be the true problem however, not oppossed to the doctor's inventions. These abominations of science will be relentless in trailing you down, and you doubt you currently have anything that can stop them yet. As for the one behind all of this madness, no one truly knows what Dr. V himself looks like, but that will be corrected tonight."

The main threats in the game would involve robotic versions of the normal Oni, as well as the Giant Oni, Roach Oni, and Blockman - each having unique traits when compared to their original counterparts. For example, Giant Oni was planned to be able to bust down certain walls in order to create shortcuts to reach you quicker - which would also prompt new and interesting reveals by baiting him into destroying certain walls in order to reveal secret passages. Another example is within the Roach Oni, who would attempt to hide in specific areas near items of interest, in order to potentially bait the player into a trap. In the case of Meka Blockman (otherwise known as Robo-Domo-Oni or Robo-Domo-Kun), he would become a much faster and more agressive version of his actual counterpart.

The process of making the game however took longer than expected, with various problems involving the coding of the Onis and their functions, as well as it becoming very time consuming. The project was eventually scrapped, though was looked back into a few months after the initial attempt. It's here that upon experimentation with more of the original game, that Ao Oni Plus came about. As such, small aspects from Machina Oni were ported into the game for certain moments, such as the Giant Oni's appearance in Mika's story, as well as Meka Blockman being brought in for non-canon areas to the story.

TriviaEdit

When playing as different characters, such as Mika and Takuro, there is a notable lack of Oni chases in certain areas. This is mainly due to the fact that some chases are for Character Oni's, with Mika's or Takuro's showing up the most in the first portion of the game. Due to the fact that she/he is still alive in this mode, it is only natural that the locations where her/his Character Oni shows up would lack chases or have new threats in them.

In the Secret Area, Dr. V's notes on the creature from Heta Oni states that he is fed up with employees attempting to change the name of the creature to 'Steve' in the directory, and that anyone caught doing so would be punished by way of using them as a test subject on the original Oni. Due to this, there is somewhat of an inside-joke in relation to Storekeeper NPC, in that he attempted to alter the creature's name to Steve and was then sent into the mansion by Dr. V.
