Cheats in Pokémon Sword, like in many other games, are codes or actions that players can input to gain advantages or alter gameplay. These can range from simple actions like infinite items to more complex ones like manipulating Pokémon stats. It's essential to note that using cheats, especially in online play, can lead to consequences such as game bans or account suspensions. Always ensure you're using cheats in a safe environment, like offline play.
