World Extend

Purchase this pack to obtain all "World Extend" songs. Future songs added to "World Extend" will be instantly unlocked at no cost. Limited-time maps may still be played for other rewards.
World Extend is a semi-free song pack for Arcaea that periodically receives new song updates.
Songs in this pack can be obtained as follows:
;Free: Every song in the pack can be unlocked individually from event maps in World Mode's Extra Chapter. These event maps are available for a limited time after their initial release (typically 2 weeks).
;Paid: Purchasing the pack immediately unlocks all songs without any additional unlock criteria. Any additional future songs are also immediately available upon release without having to play their World Mode maps. The pack costs 700 Memories, or less depending on prior World Mode unlocks. For players who have previously obtained at least 14 of these songs, the pack's cost is reduced by 100 Memories per song after the 13th.
In the v4.2.0 update, the first 20 songs in World Extend were moved to Extend Archive 1, and the premium price reset to 700 Memories for all players (subject to discounts again from v5.0 onwards). In v5.5.0, the next 20 songs were moved to Extend Archive 2.

==Trivia==
*This is the first pack with songs that can both be unlocked for memories and for free.
*From v3.6.0 to v4.2.0, the premium cost of the pack was reduced from 700 Memories for some players with prior World Extend unlocks. The cost was reduced by 100 Memories for each song including and after the 14th song, so that no players were paying more than 100 Memories per new song purchased.
*Between v3.2.2 (adding an 8th song Lapis) and v4.2.0, and again after v4.4.4 (adding the new roster's 8th song Lost Emotion feat. nomico), World Extend's premium unlock cost less than 100 Memories per song, with the value improving over time with each new song.
*lowiro revealed before the release of v3.6.0 that the entire World Extend pack would contain 20 songs in the end (prior to its v4.2.0 reset).
*This was the only pack without the sorting options available for other packs, Memory Archive and All Songs (until v3.8.4).
**Instead, this pack sorted its songs by date of release, and each folder was sorted by a specific order in accordance to the song announcements.
**With the introduction of G e n g a o z o in v3.8.6 (the 20th song), the sorting system was changed to the default sorting system, meaning players can now sort songs in their own will.
