Since this is a community-driven project, it is not available on official stores like the Google Play Store (which often hosts lower-quality "stickman" clones instead). High-quality builds are typically found through community creators.
One of the unique quirks of Mugen on Android is the AI strength. Many characters in this build have highly aggressive AI. This makes single-player arcade mode challenging. Some versions also allow "Watch Mode," where you can pick two teams and watch them fight each other, functioning like an AI tournament simulator.
