Unreal Tournament (UT99) Android

Unreal Tournament Android is an Android port of Unreal Tournament / UT99 (1999) based on the classic Unreal Engine 1 source code.

The goal of this project is to make the original Unreal Tournament playable on Android devices, including legacy Android hardware such as the OUYA console, while preserving the classic look and feel of the PC version.

Original Unreal Tournament game data is not included.
You need a valid PC installation of Unreal Tournament / UT99 and must import your own game data.

Important

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.

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 not support touchscreen controls.
