About idTech4A++
idTech4A++ is an Android runtime for launching games that use the idTech engine family and related open-source engines. Users provide the game’s own data files in an external folder, choose a supported title and game mode in the launcher, and start the runtime. The app does not replace the game data; it provides the environment needed to run compatible content on Android. The runtime supports a broad set of games, including Doom III, Quake 4, Prey (2006), Quake titles, and other engine-based projects. For some of the supported games it offers additional rendering features such as multithreaded rendering, shadow mapping, global illumination, several lighting models, and wide-character language support. Bot and full-body awareness modifications are also listed for selected titles. idTech4A++ is intended for users who already have compatible game data and want to run it on an Android device. Performance and feature availability depend on the game, data files, and hardware. The supplied description does not specify a complete compatibility matrix or installation steps for each title.
