AC DDR X2: Difference between revisions

Once the player has met the requirements for at least one song, a special Replicant D-action folder will appear during EXTRA STAGE only, containing all songs (between one and six) that the player has met the requirements for. '''Once opened, it cannot be exited.''' Gaining access to all six songs requires about 30 credits or fewer, depending on how efficiently the player is able to stack the requirements. Inside the folder, a special background music plays, blocking the player from hearing any song previews. While playing each song, the player's dance character battles a [[RINON]] clone of the song's color, who appears as a secondary background dancer. As such, the event's folder can only be accessed in Single or Double Play and not in Versus Play.

If the player clears one of the six Replicant D-action songs on EXPERT with a AA, they will earn a medal of the song's color. Once the player has earned all six medals (one from each song) in any order, the results screen of the sixth song will lead to a special cutscene depicting the camera zooming in on "The Dark One", immediately followed by an ENCORE EXTRA STAGE announcement, with the song locked to [[Valkyrie dimension]] on EXPERT difficulty (making this the seventh Replicant D-action song). As such, the player has no time to set options for Valkyrie dimension and must use the same options as their previous song (the one they just earned the sixth medal on). However, it is still possible to use the left and right buttons to change speed modifiers at the beginning of the song.

Regardless of whether the player passes or fails Valkyrie dimension, they will lose all six medals. To play Valkyrie dimension again, the player must reobtain them (thus the song can only be played once every six credits).

On August 31st, 2010, the mechanics of the event were changed slightly. It is now possible to obtain medals by getting a AA on BASIC or DIFFICULT (in addition to EXPERT); however, Valkyrie dimension's difficulty will still be locked to EXPERT. In addition, any arrow-removing options that the player has set on their sixth medal song (namely CUT1/CUT2, Jumps Off, and Freezes Off) will be unset for Valkyrie dimension. This fixes an exploit where it was possible to play Valkyrie dimension's EXPERT chart on CUT2 (making it much easier) by obtaining the last medal on Sakura Sunrise with CUT2 on (where Sakura Sunrise uniquely has few enough 12th notes/16th notes/etc. to be possible to AA with those notes removed).

On November 2nd, 2010, the VS REPLICANT boss course was unlocked, making it possible to play all 7 Replicant D-action songs in a row in one credit, on LIFE8 (all songs are played on DIFFICULT) or LIFE4 (all songs are played on EXPERT). This marks the first time it is possible to play Valkyrie dimension every credit instead of once per six credits, as well as the first time its DIFFICULT chart is accessible (in addition to its EXPERT chart).

On February 23rd, 2011, the Replicant D-action event ended (making the special folder no longer accessible), and all seven songs were unlocked for normal play. This marks the first time it is possible to play Valkyrie dimension's BASIC and BEGINNER charts. In addition, CHALLENGE charts for the last four songs were unlocked for Marathon Mode.

On April 1st, 2011, the four CHALLENGE charts that were previously Marathon Mode-exclusive were also unlocked for normal play.

In the Western releases of DanceDanceRevolution X2, due to the releases not supporting e-AMUSEMENT (required for player information to be saved across credits), the unlock mechanics of the seven Replicant D-action songs were drastically simplified. On release date (December 31st, 2010), all seven songs were locked. On July 28th, 2011, the first three songs were unlocked for normal play and the VS REPLICANT course was unlocked (allowing access to the remaining four songs). On October 1st, 2011, the remaining four songs were unlocked for normal play.
