Diamond Records

JoJo's Bizarre Adventure: Diamond Records (ジョジョの奇妙な冒険 ダイヤモンドレコーズ) is a free mobile game for Android and iOS.

The game was revealed in the January 2017 issue of Ultra Jump. It was released on February 20, 2017, in Japan.

Gameplay
Diamond Records is a 3D action style mobile game featuring content from the first four parts of JoJo: Phantom Blood, Battle Tendency, Stardust Crusaders, and Diamond Is Unbreakable. It is free-to-play with some in-app item purchases.

Players are able to fight against other known characters from the series as they appear in the anime adaptation and a number of common enemies exclusive to each part such as Vampires, Zombies (both vampire-created and Justice's army), Nazi soldiers, or delinquents in style mob battles within a number of 3D arenas also taken from locations featured in the series.

Statues
Characters are used as, in-game figures of characters from the series which have varying statistics in HP (health/hit points), ATK (attack), and DEF (defense). In accordance with their value, figures have levels going up to level 99 and a rarity value rated into stars, going from 3-Star to 5-Star rarity. 3-Star Statues are silver, 4-Star Statues are gold, and 5-Star Statues are rainbow-colored.

Statues can be organized into a of three, with one Statue being designated as leader.

If a duplicate statue is unlocked which the player already has, it combines with the statue in their collection and increases its stats.

DoDoDo Mode
Knocking out opponents fills gauges at the bottom of the screen, with character specific katakana such as オラオラオラ (OraOraOra), 無駄無駄無駄 (MudaMudaMuda), ドラララ (DoRaRaRa), or the generic beating of ドドドド (DoDoDoDo) surrounding a heart button. Once at least a single gauge is completely filled, hitting said heart will activate. During DoDoDo mode, temporary benefits will be granted to the character while the screen darkens and changes to a deep magenta color. The effects vary depending on the element of the character using it. The gauge's maximum length can be determined by the Star level of the Statue, and can be upgraded.

Elements
Each character has an element, which is displayed as an icon next to their name.

Skills
Every character comes with their own where the player can use materials to upgrade the Statue's stats and unlock skills. Certain areas of the Growth Tree are locked and require Expansion Keys in order to activate them.

There are regular skills which are shown by a blue icon and can be used infinitely with a cool-down. SP skills are shown in pink and have limited usage. Some SP skills also have cinematic cutscenes.

Minds
Statues can be equipped with special items called, which consist of an image from various scenes of the anime. They vary in rarity from 1-4 stars, and can boost stats, grant other bonuses under special conditions, or unlock exclusive skills for characters. Statues have a limit called CP to determine how many Minds can be equipped. One-star Minds have a copper frame, two-star Minds have a bronze frame, three-star Minds have a silver frame, and four-star Minds have a gold frame. Minds that can be equipped have levels from 1-10, with stronger effects when the level is increased. Equipping multiple copies of the same Mind on a Statue results in a Mind Link (マインドリンク Maindo Rinku), which increases the bonuses of the equipped Mind.

There is another type of Mind which can only be used once by combining with a Statue rather than staying in the player's box. These Minds are experience multipliers and have different icons. One-star experience Minds are bronze, two-star Minds are silver, three-star Minds are gold, and four-star Minds are rainbow-colored. At the moment, there are a total of 425 Minds that can be collected.
