Installing Nebula is a straightforward sideload: you download the APK directly from the Nebula GitHub Releases page and open it on your device. Sideloading means installing an app from outside the Google Play Store — Android allows it, but you must first tell Android which app (your browser or file manager) is permitted to install packages this way. No root access is required at any stage.Documentation Index

Android may show a warning about installing apps from outside Google Play. This is expected behavior for any sideloaded APK. Only install APKs obtained from a Nebula release you trust — the official source is the Releases page of the Nebula Launcher GitHub repository.
Installation steps
Download the latest Nebula APK
On your Android device, open your browser and navigate to the Releases page of the Nebula Launcher GitHub repository. Find the most recent release, expand its Assets section, and tap the
.apk file to download it.Open the downloaded APK
Once the download finishes, tap the file in your browser’s download notification or open it from your file manager. Android will begin the installation flow.
Allow unknown app installs if prompted
If Android blocks the installation with a message like “For your security, your phone is not allowed to install unknown apps from this source”, tap Settings in the dialog, then enable Allow from this source for your browser or file manager. Return to the file and tap Install again.
Open Nebula Launcher
After installation completes, tap Open, or find Nebula Launcher in your app drawer and launch it.
Create or sign in to your Nebula account
On the sign-in screen, choose Create account or enter your existing Nebula credentials. Your Nebula account is separate from your Among Us account and is used for launcher access and Nebula services.
Verify your email if prompted
If this is a new account, Nebula may ask you to verify your email address before proceeding. Check your inbox for a verification message and follow the link, then return to Nebula.
Grant storage access
When the storage-access prompt appears, tap Grant Access. Android will open the all-files access settings screen — locate Nebula in the list and enable the permission. Then return to Nebula. See Granting storage access below if the prompt does not appear or you need to grant it manually.
Confirm Among Us 2026.6.5 is installed
Nebula will check your Among Us installation before launch. Make sure Among Us version 2026.6.5 (version code 7045, in-game label 17.4a) is installed on your device. If it is not, install the correct build before continuing. See the Requirements page for details.
Select a profile and install mods
On the Profiles page, select the profile you want to use (or create a new one). Then open the Mod Store to browse and install verified Android-compatible mods, or import a compatible DLL or ZIP-based mod package manually.
Press Launch
With a profile selected and your mods installed, tap Launch. Nebula will stage the active profile and hand control to FusionCore to start Among Us with mods loaded.The first launch takes significantly longer than later launches — FusionCore needs to prepare the runtime and generate IL2CPP interop assemblies for your installed game version. This can take up to around 8 minutes. Do not close the app while the loading indicator is moving. See the First Launch page for a full explanation of what happens and what to do if the process is interrupted.
Granting storage access
Nebula requires Android’s all-files access permission to manage the sharedFusionCore/com.innersloth.spacemafia/ directory. This folder holds the BepInEx runtime, active plugins, generated IL2CPP interop assemblies, and logs — all the pieces FusionCore needs to load mods into Among Us. Without this permission, Nebula cannot stage mod files or start the game.
The permission prompt appears automatically the first time you open Nebula. If you dismissed it, or if Android reports that the permission was not granted and keeps showing the prompt, you can grant it manually:
- Open Android Settings → Apps (or Application Manager).
- Find and tap Nebula Launcher.
- Tap Permissions.
- Find Files and media or All files access (exact label varies by Android version and manufacturer skin).
- Select Allow management of all files or the equivalent option that grants full storage access.
- Return to Nebula. The prompt should no longer appear.
Ready for what happens next? Head to the First Launch page to understand the IL2CPP generation process and what to expect the first time you tap Launch.
