A modded APK is an Android application that has been altered from its original version to provide additional features and appearances.
Mods have origins on the PC side of gaming in the 1990s, where they were typically used by gamers to customize games like Doom or Grand Theft Auto to make them run smoother or behave better. In a nutshell, mods are just files which provide new functions for Minecraft and other applications. These new features can be in any shape, size or flavor and often require players to learn how to use them before they become comfortable with their inclusion in-game. I should also mention that it’s not for everyone; mods can make a game challenging for more casual players as well as change gameplay elements more drastically than some people are willing to deal with.
