Before installing Nebula, confirm that your device and your Among Us installation meet every requirement listed here. Most modern Android phones pass all of the hardware and OS checks automatically — the version-specific Among Us requirement is the one most users need to act on.
Among Us must be installed from a source you are authorized to use. Nebula does not include the Among Us APK and is not affiliated with Innersloth or Epic Games.

Requirements checklist

1

Android 8.0 (API level 26) or newer

Nebula’s minimum SDK is API 26, which corresponds to Android 8.0 Oreo. To check your Android version, open Settings → About phone → Android version. Devices running Android 7.x or earlier cannot install Nebula.
2

64-bit ARM device (arm64-v8a)

Nebula’s native components and the FusionCore runtime are compiled exclusively for the arm64-v8a ABI. Most Android phones released in 2018 or later use a 64-bit ARM processor and meet this requirement. To confirm, check your device’s specifications or look up your processor model. 32-bit-only devices and x86/x86_64 emulators are not supported.
3

Among Us 2026.6.5 (version code 7045)

Nebula requires exactly Among Us 2026.6.5, which carries Android version code 7045 and is labelled 17.4a inside the game. Both the version name and the version code must match — a different build with the same version name is rejected. See Checking your Among Us version and About the version lock below.
4

Sufficient free storage

You need enough free storage to hold all of the following simultaneously:
  • The Among Us game data itself
  • The FusionCore ARM64 runtime and Unity libraries
  • Generated IL2CPP interop assemblies (produced during the first launch)
  • Your installed mods and their assets
The exact amount depends on your mods, but plan for several gigabytes of free space. Low storage during the first launch can interrupt IL2CPP generation.
5

Internet access

An active internet connection is required to:
  • Create or sign in to your Nebula account
  • Download the FusionCore runtime and Unity dependencies during first launch
  • Browse and install mods from the Nebula mod store
After the runtime is prepared and mods are installed, you can launch the game offline, subject to Nebula’s session grace period for account verification.
6

All-files storage permission for Nebula

Nebula needs Android’s all-files access (the MANAGE_EXTERNAL_STORAGE permission) to read and write the shared FusionCore/com.innersloth.spacemafia/ directory, which contains the BepInEx runtime, active plugins, generated interop assemblies, and logs. Nebula will prompt you to grant this permission on first launch. Without it, Nebula cannot stage mods or start the game.

​
Checking your Among Us version

Nebula reads both the version name and the version code from the installed package and compares them against its required values. The easiest way to verify you have the correct build before installing Nebula is to check it from Android’s app info screen.
  1. Long-press the Among Us icon and tap App info, or go to Settings → Apps → Among Us.
  2. Look for the Version field. It should read 2026.6.5.
  3. To confirm the version code as well, you can launch Among Us and check the version string displayed on the main menu screen — it should read 17.4a.
If Nebula is already installed, it performs this check automatically when you press Launch and tells you whether you need to upgrade or downgrade.

​
About the version lock

Nebula supports exactly one Among Us version at a time because of how IL2CPP works. Among Us on Android is compiled with IL2CPP, which converts the game’s managed C# code into native ARM64 machine code. To let mods call into the game, BepInEx needs a set of interop assemblies that mirror the game’s original C# types and method signatures. These interop assemblies are generated from the metadata of the specific game binary you have installed. Even a minor patch to Among Us changes method offsets and type layouts, breaking any interop assemblies generated for a different build. Nebula and FusionCore therefore pin to a single tested version — 2026.6.5 / code 7045 / in-game 17.4a — and warn you to upgrade or downgrade if your installed build does not match.
If Nebula tells you to upgrade or downgrade Among Us, do not update through Google Play to an untested newer version. Obtain the exact required APK from a source you trust and install it manually, or wait for Nebula to add support for the newer version.
