Left4Dead2 External Cheat is a proof-of-concept project for the Source Engine featuring an OS-ImGui overlay.
This project is unfinished and can be optimized or extended with additional features. Unlike an internal cheat, it does not inject code into the game process. Instead, it creates an external overlay on top of the Left 4 Dead 2 game window.
The application locates the client.dll and engine.dll module base addresses, uses known offsets (e.g. dwLocalPlayer) to read the game's memory, scans the entity list, and retrieves information such as entity positions, health, team, zombie class, and life state.
For example, it can distinguish between Survivors, Special Infected (Smoker, Boomer, Hunter, Spitter, Jockey, and Charger), the Tank, the Witch, and Common Infected.
It also reads the game's view matrix to transform 3D world coordinates into 2D screen coordinates, allowing ESP elements such as 2D boxes, snaplines, health bars, names, and distance indicators to be rendered accurately on the overlay.
