Dance Dance Revolution (2013 video game)

The game retains the Extra Stage system from previous games, which rewards players with an additional stage by fulfilling certain requirements. Players are required to obtain 9 stars decided by the player's grades as in DDR X3 vs 2ndMix. Extra Stage is played with a forced Battery dance meter containing 4 lives. Obtaining a step judgment of "MISS" or "N.G." depletes one life on the player's battery; depleting all four lives will fail the stage. While Extra Stage is initially accessible to all players, starting on the major update on May 12, 2014, Extra Stage is only accessible for premium users.

To celebrate the birthday of the game's sound director, Yasuhiro Taguchi (better known as TAG), three new Extra Stage songs were added on March 25, 2014. Clearing songs made by TAG will cause flower icons to appear in the song jackets, and the three new songs, in order: esrev:eR, ÆTHER, and SABER WING (satellite silhouette remix) will be made available.

Starting in May 2014, if any player earned an Extra Stage, can access a new music folder, Extra Attack, containing new songs. A "Survived Bonus" gauge can be filled by playing these songs; passing the songs will unlock the stepchart the player played on. Challenge stepcharts for several songs are also available under an additional folder, Oni no Extra Attack (鬼のEXTRA ATTACK) accessible for a limited period from time to time, which forces players to play with Sudden Death dance meter (scoring a single "MISS" or "N.G." will immediately end the game). This event ends on December 17, 2015 & certain songs are unlocked for regular play while the other part are still in this folder.

A bug in the game caused the post-Extra Stage, Encore Extra Stage to be made available after an October 2, 2013 update of the game, which was not implemented due to the revenue-sharing system. The bug allowed players who score AA or higher in Blew My Mind on Expert to access Another Phase on Expert, although the song is already accessible normally. It was rectified in an October 8, 2013 update, and Encore Extra Stage is once more inaccessible.

The first BEMANI-wide event, Private BEMANI Academy (私立BEMANI学園, Shiritsu BEMANI Gakuen) started on April 24, 2013 and ended on December 19, 2013. Among the BEMANI games that participate in the event other than DDR include beatmaniaIIDX, pop'n music, GITADORA, jubeat, and REFLEC BEAT. In this school-themed event, players needed to play each of the six BEMANI games to fill the friendship meters between eighteen BEMANI artists that were grouped into two each. Obtaining 100% friendship with a group would unlock a collaboration song on all games. What game the player played would also influence the increasing rate of the meter; for example, playing DDR would boost the rate to unlock the song by TAG and U1-ASAMi (Synergy for Angels) by 5 times, but it would also decrease the rate to unlock the song by 猫叉Master+ (Nekomata Master+) and L.E.D. (GAIA) by half. In addition, while not fully participating in the event, playing Dance Evolution ARCADE, Sound Voltex, and Quiz Magic Academy Kenja no Tobira Season2 would also help boost the friendship meter. After unlocking all nine collaboration songs, players could befriend dj TAKA and DJ YOSHITAKA to unlock the last song, Elemental Creation.

Triple Journey, a collaboration event between DDR, jubeat, and GITADORA started on August 1, 2013 and ended on September 2, 2013, coinciding with a related BEMANI event, Kupuro Mimi-Nyami Pastel-kun no Minnade Uchū Sensō. In this event, for every day in the month of August, players could check the event's e-Amusement GATE website to receive mails that contain new songs. The first day of the event gave a new song (sola) to all games. From then on, each game alternated on receiving the mails that contain crossover songs from the others; all games would receive a total of 13 songs by the end of the event. Eventually the event culminated on the last day which gave another new song (Triple Journey) to all games.

The second BEMANI-wide event, Nettou! BEMANI Stadium (熱闘！BEMANIスタジアム, Nettō BEMANI Stadium) started on December 19, 2013 and ended on July 23, 2014. All games participating in Private BEMANI Academy returned to participate in this event again, with SOUND VOLTEX now fully participating in the event and also receive the new songs; newcomer include ミライダガッキ FutureTomTom. In this event, players could collect three baseball cards with emblem based on various BEMANI artists and characters by playing each game. These baseball cards could then be trained to increase its skill, then used to battle other players in baseball tournaments, which required entry tickets (received by playing any of the nine games). Winning the games unlocked new songs for play. The event is split into two parts, with the game Steel Chronicle VICTROOPERS also joining the event in the second part. After unlocking all songs, players could participate in the final tournament, which unlocked the song IX for play. While this event ends, all songs can unlock via EXTRA ATTACK.

The 10th floor infection event between DDR and SOUND VOLTEX II -infinite infection- (and III -Gravity Wars-) ran from June 26 to July 10, 2014, with additional rerun from July 30 to August 6, 2014. Similar to previous Floor Infection events, by playing SOUND VOLTEX, players can raise a meter, which upon reaching a certain level will unlock a new song in DDR. A total of 3 songs can be unlocked through this event.

The third BEMANI-wide event, Hakken! Yomigaetta BEMANI Iseki (発見！よみがえったBEMANI遺跡) or "Discover! BEMANI Ruins" started on July 24, 2014. The participating games other than DDR are beatmaniaIIDX, pop'n music, GITADORA, jubeat, REFLEC BEAT, SOUND VOLTEX, Dance Evolution ARCADE, ミライダガッキ FutureTomTom, and BeatStream. In it, players can collect stones by playing each of the BEMANI games participating to build pyramids divided into six parts, all of which unlock new crossover songs. All games have their own pyramids with the exception of SOUND VOLTEX, Dance Evolution, and BeatStream, which can be played to boost the rate to unlock songs on other games.

In addition, there are three clocks containing three all-new collaboration songs. Players from all of Japan can fill these clocks; upon completing one, a new song will be available for everyone for a single day.

On July 23, 2015, all songs can unlock via EXTRA ATTACK folder.

The Boss On Parade event was started on January 22, 2015. In the event, five crossover songs from other Bemani games are available for unlock by collecting medals obtained by clearing a specific set of songs. These songs are usually tied to the artist credited for the crossover songs, tied to the original games they appear in, or else have an aesthetic connection (such as songs titled with themes relating around fire and heat being required to unlock クリムゾンゲイト (Crimson Gate)). Players may not clear the same song repeatedly to obtain the medals. By unlocking all five songs, players are able to unlock a new song, Truare!. As of February 16, 2015, the condition to unlock each song is relaxed; clearing other songs not eligible nets players with fragments of the medals, and players can play the eligible songs repeatedly to earn the medals.

This event ends on December 24, 2015 & all these songs are unlocked for regular play.

The continuation of "Replicant D-Action" event from DDR X2, this event, available since March 5, 2015, once again allowed players to unlock a new folder containing six new boss songs. This time, instead of fulfilling a different set of objectives, players simply had to fill song meters (represented by tubes) which were presented at the end of a game credit. The event was directly connected with the "Boss On Parade" event and required players to clear Truare! first. One could choose to pick one out of 5 nitro tubes (and thus five songs) to fill; once it is full, players gained access to the D-Ignition folder during Extra Stage, which had a different interface and system music. Once players chose to enter, they might not exit back to the regular song selection screen.

By scoring AA or higher on Expert in one of the five songs, players would earn a colored orb. Having all five orbs unlocked a sixth song, EGOISM 440. Selecting this song immediately discarded all orbs; regardless if players passed or failed this song, they would have to earn all orbs to unlock the song again. If players managed to score AA or higher in EGOISM 440 on Expert, they could access the Encore Extra Stage, MAX. (period) on Expert with 1.5x speed, Reverse scroll, and Risky (scoring one MISS or N.G. immediately fails the stage) options turned on. As with the Encore Extra Stage of "Replicant D-Action", players immediately played the stage following a short cinematic; no time was allowed to change options.

The second phase of the event was started on March 26, 2015, which was accessible for players who managed to pass Encore Extra Stage. Players could collect another round of colored orbs which allows access to MAX. (period) in Extra Stage in all difficulties, including Challenge (a different stepchart from the one found in Dance Dance Revolution Extreme). In the same vein as EGOISM 440, choosing the song discarded all orbs. If players managed to score AA or higher in MAX. (period) on Challenge, they were granted access to Encore Extra Stage, Over The "Period" on Difficult with all prior Cut options disabled and a special Risky Dance meter: scoring GREAT, GOOD, MISS, or N.G will make you fail the stage.

As of April 9, 2015, conditions for the event had been lowered; for the first phase, players could play EGOISM 440 on Difficult to access MAX. (period) on Difficult also, while in the second phase, playing MAX. (period) on Expert would net access to Over The "Period" on Basic.

As of May 1, 2015, conditions for the event had been even lowered in the second phase; Clearing MAX. (period) on Difficult as the Extra Stage led to Over The "Period" being played on Beginner as the Encore Extra Stage. However, on Double Play, where Beginner was not available, Over The "Period" would be played on Basic instead.

As of July 2, 2015, conditions for the event had been even lowered in the second phase; Clearing MAX. (period) on Basic as the Extra Stage led to Over The "Period" being played on Beginner as the Encore Extra Stage. However, on Double Play, where Beginner was not available, Over The "Period" would be played on Basic instead.

As of August 6, 2015, all 8 songs can be unlocked via EXTRA ATTACK. Conditions like Truare! or 5 nitros are still exist, though but exist changed methods: For the first phase, players could play EGOISM 440 on Expert to access MAX. (period), while in the second phase, unlocking MAX. (period) on Expert to access Over The "Period", for the third phase, unlocking Over The "Period" on Expert to access MAX. (period) on Challenge and finally for the fourth phase, unlocking MAX. (period) on Challenge as the Extra Stage led to EGOISM 440 being played on Challenge at the next play.

This event ends on December 24, 2015 & all these songs are unlocked for regular play. All players can access to Over The "Period" on Challenge as Extra Stage, and cannot unlocked via EXTRA ATTACK.

The fourth BEMANI-wide event, BEMANI Summer Diary 2015, was started on July 23, 2015 and ended on October 26, 2015. The goal for this event is to fill a diary with entries that display images of characters from the games that participate in this event (the same as Hakken! Yomigaetta BEMANI Iseki minus ミライダガッキ FutureTomTom, which ceased receiving e-Amusement service on July 31, 2015). Each entry features two characters representing two games. Playing the participating games normally fills the entry by 4.9% per credit, while playing with Premium Mode (using PASELI) fills by 7.4%. Once it is full, a new song will be unlocked in one of the two games featured on the entry. Additionally, playing the two games featured on the image multiplies the increase rate by 3x, and playing during the date and the next 7 days the song is made available to unlock multiplies the rate again by 3x and 1.5x, respectively.

For example, the 3rd and 4th entries feature Baby-Lon (representing DDR) and Pastel-kun (representing REFLEC BEAT). In filling the 3rd entry, one of these games can be played for the 3x multiplier, but only DDR will receive a new song, Sakura Mirage. Similarly, the 4th entry can be filled quickly by playing these two games, but only REFLEC BEAT will receive a new song, ΔMAX. The entries are to be filled consecutively; one cannot jump to the 3rd entry to unlock a song for DDR, but instead have to fill the 1st and 2nd entries (for beatmania IIDX and SOUND VOLTEX BOOTH) first.
