You can deploy and run an Unreal app directly on the device.
1 - Verify System Requirements
Steps
- Verify that you have installed the necessary prerequisites to run the HoloLens 2. See Windows Mixed Reality Development Requirements for more information.
2 - Required Setup
Before you can deploy an Unreal application to the HoloLens, you must configure the HoloLens and become familiar with its basic operations.
For more information on initial HoloLens setup and configuration, see Get started with HoloLens.
Steps
-
Make sure that your HoloLens is charged.
-
If this is your first time launching the HoloLens, turn it on and proceed with the calibration process.
-
Log in with your account or create a new account.
-
On the HoloLens, open the Settings menu
-
Open Update & Security.
-
Open For developers.

Enable Use developer features.

Enable the Device Portal.
3 - Install a Package to the HoloLens 2
If you do not already have an app built and available for the HoloLens, see Packaging an App for the HoloLens 2 for more information on packaging an app for the HoloLens 2.
In the steps you will load two files, an .appxbundle** file and an ** .appx file. The .appxbundle** file is the game's package. The ** .appx file is the dependency package containing supporting files for the target architecture (arm64 or x64). The dependency package only needs to be installed a single time per device. If you have already installed the dependency file, just continue with the installation without selecting an optional package. If you reflash your device, you will lose everything that had been deployed to the device, including the dependency packages.
