Three main reasons:
The official game is a resource-intensive PC title that relies heavily on CPU power for its soft-body physics calculations. Current mobile hardware generally struggles to handle the complex real-time physics calculations the game requires, which is why the developers have focused exclusively on the PC platform.
Los desarrolladores han declarado en múltiples ocasiones que no hay planes para una versión nativa de Android . No existe un "BeamNG.drive APK oficial".
There is for Android. BeamNG.drive is a PC-exclusive title that relies on high-end soft-body physics that mobile hardware cannot natively support.
Because realistic physics are hard to run on phones, many developers on Itch.io release "tech demos." These games might look simple, but they offer satisfying crash physics similar to the early days of BeamNG.
