What is a trainer? A trainer is a software tool that modifies the game's behavior, allowing you to cheat or manipulate certain aspects of the game. In this case, we're looking for a trainer that enables the "Fling" feature.
For the uninitiated, a trainer is a small background application that modifies the memory of a game while it is running. Unlike mods (which change game files), trainers toggle specific flags in real-time—like infinite health, one-hit kills, or unlimited gadgets.
