Gacha Nebula is a fan-made modification of Gacha Club created by the modder Noxula, with contributions from Deana_3, LeeOwO, Agoras, and Miko. It is not an official title from Lunime, the developer of Gacha Life and Gacha Club, but a community project that expands upon the original game's character creator and Studio Mode. The mod introduces a space and nebula themed interface and adds over 2,000 new customization items. The mod retains the core systems of Gacha Club, including the character creator, Studio Mode, and battle system. Users build characters step by step, selecting from a larger pool of body types, faces, hairstyles, clothing, and accessories. The expanded wardrobe includes tops, jackets, skirts, pants, shoes, hats, wings, tails, glasses, bags, and masks. Many items have their color restrictions removed, allowing for greater customization. The hair system is layered, allowing users to mix front hair, back hair, and ponytails. A notable feature is the individual creator credit attached to each new item, visible by tapping it. All items are unlocked from the start. Gacha Nebula is available for Android as an APK file, as well as on Windows PC and some Chromebooks. The latest version is v1.7.0.2. Because Google Play does not allow unofficial game mods, the software is distributed independently through Noxula's official itch.io page and trusted mirror sites. Installation on Android requires enabling the installation of apps from unknown sources in the device settings. The mod is free to download and use.
