The Roblox Mod Menu for PC gives players the ability to access advanced features and modify their gameplay, including options like speed boosts, teleportation, and unlocking premium items. This mod enhances the gaming experience by offering more customization and control over the game. However, it's important to note that using mod menus can violate Roblox's terms of service, risking account penalties or bans, so players should be cautious when using them.
