Beatmania IIDX 23: Copula
Beatmania IIDX 23: Copula is the 23rd installment of the Beatmania IIDX series. The first location test was held at the Tokyo Lesiure Land #2 location in Akihabara, Japan from July 10 through July 12, 2015. It was released on November 11, 2015. It was the last entry in the Beatmania series made by Konami Digital Entertainment before the division was renamed Konami Amusement.
Gameplay
For more information about the gameplay of Beatmania IIDX in general, please refer to Beatmania IIDX#Gameplay.Beatmania IIDX tasks the player with performing songs through a controller consisting of seven key buttons and a scratchable turntable. Hitting the notes with strong timing increases the score and groove gauge bar, allowing the player to finish the stage. Failing to do so depletes the gauge until it is empty, abruptly ending the song.
Beatmania IIDX 23: Copula retains the core gameplay introduced in the first game in the series, and builds upon features added in subsequent versions. Notes fall from the top of a vertical track, and players are required to either press buttons or turn turntables as they reach the bottom. Copula introduces a number of new features and gameplay elements to this base, including a new "hell charge note", additional beginner note charts available in standard mode, an "Assisted Easy" difficulty mode, and various other adjustments and features.
Gameplay changes
Hell charge notes
In Beatmania IIDX 17: Sirius, "charge notes" and "backspin scratch" notes were introduced, where the player has to hold a button or continuously spin the turntable for a specified amount of time. Traditionally, these charge notes were effectively treated as a note at the start and end, with the end note being automatically treated as missed if the note is not held. In Copula, a new type of charge note, the "hell charge note" was introduced, in which the Groove Gauge meter would continuously drop or increase during the extent of the charge note, depending on whether it was correctly held. Additionally, with hell charge notes it became possible to recover from failing to hold the note by pressing and holding after the correct start point.Assisted Easy mode
In addition to the Easy mode available in previous versions, which reduced the rate at which the Groove Tauge drops when notes are missed, Copula added a new "Assisted Easy mode", in which the rate at which the gauge drops is the same as in Easy mode, but the threshold for clearing a chart is reduced from 80% to 60%. Charts cleared in this manner are marked as being "assist cleared".Class mode changes
Class mode is a mode in which players select from a series of preselected 4-song courses. The difficulty level of the highest level course cleared is often used as an indicator of the overall strength of the player.In Copula several changes were made to the Class mode system. First, options were added to play a Class mode course with notes mirrored, with the Groove Gauge dropping faster than normal or both. These options were previously available in Beatmania IIDX 22: Pendual, but Mirror mode was selected based on whether the current day was "present phase" or "future phase", and EX mode required payment to be made using Konami's Paseli electronic currency; in Copula both options are available through normal menus.
Additionally, Chūden, a new class rank was added in-between classes 10th Dan and Kaiden, while Class mode courses for dual-side play were changed from having 3 tracks to 4 tracks and began on 7th Kyū instead of 5th Kyū.
Changes to song selection menus
Certain beginner charts which were previously only available in the "step-up" training mode are now available in other modes such as standard mode, under the "All Beginner" folder. Various other minor changes were made to the song select UI, including a rainbow indication for unlocked hidden tracks, and new sort options.Unlocking Modes
Rainbow Tickets and Pulaco Tickets
Rainbow Tickets is a Paseli-Purchasable Item which was available on November 26, 2015. The effect of this ticket would temporarily unlock any locked songs in Pendual and Copula, and the Leggendaria folder songs for only one session of gameplay. Tickets also gave boosts to unlocks when used in any Unlocking events. Note that the Rainbow Tickets will not work on any past unlock event songs from tricoro and SPADA, as these songs are regularly unlocked. Rainbow Tickets have a validity of 60 days upon purchase. The tickets would all be sold out on October 19, 2016, and expired on October 26, 2016.In an update on February 3, 2016, most of the unlocks from Pendual can be unlocked by purchasing the charts on the Pulaco Ticket store using Pulas. The Pulaco tickets function the same way as unlocking using Angel Cards from tricoro and the Sunlight Holograms from Pendual.
Season Line
Season Line is the Extra Stage system which debuted on November 19, 2015, in which players must clear the songs through the first three stages in the game to access the songs. Each of the Season Line songs is based on a seasonal theme. Unlike the past Extra Stage Systems, there are no specific song conditions in which players have to play for unlocking. The six Songs and their respective Season Lines were:- Dunkel Weihnachten: nightmare before oversleep
- 冬尽く小江戸 : 麗 ～うらら～
- Spring Festival: La dolce primavera
- occasional rain: 紫陽花 -AZISAI-
- kilogramme de l'aventure: か・し・ま・し☆PUMP UP!
- えきねこ : 駅猫のワルツ
Initially, Season Line songs do not have One More Extra stages, just like SPADA's Leggendaria and tricoro's Limit Burst Extra Stage System. In an update starting September 15, 2016, all six of the Season Line songs could be unlocked by playing the songs once during the Extra Stage, and the unlock must be done on one-player mode only. A coloured emblem of the corresponding Season Line song would be displayed next to the difficulty level when it's unlocked. When the player obtains all six emblems, the player can play NZM as their One More Extra stage song under the corresponding difficulty unlocked for the six songs. The gauge used for this stage is specially designed to only decrease for missed notes and doesn't recover. If the player fails the song, the emblems will be confiscated and the player must collect them by playing all the six songs again, but the play became easier on subsequent attempts, and allow the gauge to recover ). Once the final boss is cleared regardless of the type of gauge used, NZM would be unlocked for regular play.
Kaitsū! Tokotoko Line
The first major unlocking event for this game began on November 26, 2015, and ended on April 24, 2016. This unlocking event objective is to build a railway and their station facilities through five areas in order to unlock the songs. Building a railway requires Material Points, which can be obtained by playing songs in the game. Material Points can be boosted further depending on the partners selected, or fulfilling conditionsCompleting the railway in an area would be a given rank promotion and allowed players to select one of the songs for unlocking. The player can anytime revisit the area for further unlocks. Each area has one to three stations to build, building one of them would earn Pulars. Building all of the stations in the same area would unlock the console-exclusive and Revived Songs. Finally, building all the 12 stations throughout five areas would also unlock Blue Spring Express and the player can proceed to the second part of the event.
The second part required players to build facilities in the same five areas and likewise, building facilities would require filling up the Development Happiness Gauge certain times in order to unlock them. Building one facility in an area would earn Pulars; building all the facilities in the area would also unlock songs. When the player completely built all 11 facilities in all five areas, the final song 真 地獄超特急 -HELL or HELL- would also be unlocked for regular play and the event is completed.
This event have a total of 16 songs to unlock.
Expert Mode
The Expert Mode in which players play four consecutive songs without stopping was initially absent in the game's release, but it was made available through an update on February 3, 2016. Similar to the past instalments, players are required to select a course of four songs and play them in order without emptying the gauge to clear the course. Most of the course features from PENDUAL were retained, including the ability to unlock songs under the Secret Course Folder.Likewise, in order to unlock the secret songs, players are to play the respective secret course a certain number of times. The progress is shown by a gauge at the end of the gameplay, and the increase rate would depend on their performance and the modifiers used in-game. Filling the gauge completely would then unlock the song for normal play, even though the song has been previously unlocked.
Currently, 13 songs are available for unlocking in this mode.
Mystery Line
The second major unlocking event began on April 27, 2016. The event folder would appear between My Favourite and Level Difficulty Folders during the game's final/Extra Stage, with an on-screen alert for any new destinations available. Players may not exit the mode once the folder is opened, and switching play styles between Singles and Doubles will be temporary disabled.The unlocking process is split into two parts. The first part is the ‘Mystery Line’ folder, each destination would be chosen at random and only one would be visited at a time. Players can also choose to redeem three Rainbow Tickets if they want to change the destination, but the player must explore the area once decided. Note that playing the song once regardless of the difficulty selected would be saved onto the second part.
The second part is the ‘Mystery Explore’ folder. A pool of songs for the song's corresponding theme and their charts would be selected at random. Playing a song fills up a portion of a pie chart-like gauge that would unlock the chart for normal playing, with a rate determined on the selected level and the clear type. Depending on the difficulty chosen for unlocking, more songs were required to be played and were also based on the areas being explored. Regardless of the outcome, each play would remove one star from the parking counter. When all the three stars were used up, the train would move on to a new destination the next time the player enters the folder, whether the chart has been unlocked or not.
Some destinations are also marked secret and would be priorly selected over normal destinations. To access these destinations, players must further satisfy certain song conditions during the first two stages in gameplay, with some charts needing to be unlocked in advance.
There are sixteen songs which have to be unlocked in this event.
