Unreal Tournament (UT99) Android

README  |  ROADMAP  |  DOWNLOAD

Note

Unofficial fan port. No game data included. Requires legally obtained Unreal Tournament v1.400 game files. This project is not official and is not endorsed by Epic Games.

Important

This app is 32 bit only! It won't install on your phone? Then it might only accept 64 bit apps. There are no plans on making this app compatible with 64 bit only CPUs.

Video games on smartphones are great, but not user-friendly if they require more than two thumbs to control. For this reason, this port is designed for controller input and does only offer basic touchscreen controls.

This project is for preservation, experimentation and personal use only.
Unreal Tournament, Unreal Engine and related trademarks are owned by Epic Games.
This project is not affiliated with or endorsed by Epic Games.

◈ Features

• Android support for newer Android devices up to Android 13 (no 64 bit devices).
• OUYA (Android 4.x) legacy support - with a lower internal render resolution for better performance on legacy hardware.
• Improved Game Data Import – Unreal Tournament data can be imported via folder or ZIP selection and automatically installs to the app's data folder.
• Android 8+ Storage Access Fixed – SAF support added for modern Android versions where direct SD/file access is restricted.
• Legacy storage behavior friendly for old sideload devices (place game data on your microSD/UT99 folder).
• Local WiFi multiplayer and botmatches are available.
• Added touch controls for use without a controller.

Note

Expect occasional issues, especially on very old Android devices or unusual controller mappings.

▣ Requirements

• Android device with OpenGL ES 2.0 support.
• Android 4.1 / API 16 or newer.
• ARMv7 compatible device for the current build.
• Android-compatible game controller recommended.
• Original Unreal Tournament / UT99 PC game data v400.

Required game data folders:

2. Copy your Unreal Tournament game data to your device, either:
   • as an extracted folder, or
   • as a ZIP file.
3. Start Unreal Tournament.
4. If no game data is found, the installer screen appears.
5. Choose one of the following:

◇ Default controller layout

The default controller mapping is designed for Android gamepads, OUYA and handheld devices such as Retroid-style controllers.

Control	Action
Left Stick	Move forward / backward / strafe
Right Stick	Look / turn
Left Trigger	Alternate Fire
Right Trigger	Fire
Left Shoulder	Previous Weapon
Right Shoulder	Next Weapon
A / right face button	Jump
B / bottom face button / OUYA O	Crouch
Y / left face button / OUYA U	Walk
X / top face button / OUYA Y	Wave
D-Pad	Menu navigation / in-game navigation depending on context
Start	Pause / menu
Back	Back / cancel depending on context

Note

Button names can differ between Android controllers.
If movement or looking feels wrong, open the in-game controls menu and reassign the affected controls.

▣ Game data notes

Game data is not bundled with this repository.

You need to provide your own legal copy of Unreal Tournament / UT99.
The Android installer checks for the required folders:

System
Maps
Textures
Sounds
Music

If these folders are missing, the game will not start and the installer screen will ask you to select a valid folder or ZIP file.
