It is based on the direct-to-video film Bratz: Rock Angelz and the line of dolls affiliated with the same name.

The game loosely follows the film's plot, where the Bratz start a fashion magazine.

They later receive an invitation from a nightclub in London to perform at a concert venue and outsell their rival competitor, Your Thing magazine.

[2] The player controls one of the four Bratz girls (Yasmin, Cloe, Sasha, and Jade) who are attempting to launch their own teen magazine.

[3] The player can explore 4 different locations; Stylesville (where the Bratz live), London, Paris, and the mansion.

The objectives of the game are triggered when the player takes the correct Bratz girl to a speech bubble.

Each girl carries a cell phone, used to send messages between characters, check the amount of blings owned, and the location of the next objective.

The player has to play with the certain Bratz character and take things to solve a puzzle (for example give a camera to a colleague).

Jade gets accepted as an intern for a famous fashion magazine named Your Thing, run by Burdine Maxwell.

However, Burdine's other interns, Kirstee and Kaycee, who are nicknamed the "Tweevils" by the Bratz, devise a plan to get Jade fired.

A fashion show venue in Paris asks the Bratz to headline their Ooh La La fashion show, and after completing the articles for their second issue, they arrive in Paris and discover the venue was acquired by a company called "Pink Industries".

They then realize the company is related to Your Thing after the Tweevils arrive, so the Bratz spy on them to gather information on their decision to purchase the venue.

The Tweevils give the Bratz a plan that revolves around blackmailing Burdine by taking a photo of her without her awareness.

The Bratz decide to follow the plan by sneaking into a salon where Burdine is in the middle of a skincare regimen, with Yasmin being chosen to take the photo due to her flexibility.

After coping with Burdine's conspiracy, the Bratz eventually perform their fashion show, and like their London venue, it was commercially successful, along with the magazine selling an abundance of copies.

Jade immediately contacts both Yasmin and Sasha, who are both disappointed in the results of their dream jobs, leading both of them to arrive back home to confront Burdine and the Tweevils.

With Burdine feeling defeated, the Bratz celebrate their triumph by performing their final rock show at the mansion.

The reviewer also described it as an "unpleasant, explotative drivel aimed at girls who would almost certainly have more fun staring at a blank TV set".

The first one, Bratz: Forever Diamondz, was released for the PlayStation 2, GameCube, Game Boy Advance, and Nintendo DS in 2006.
