## Esp
An internal ESP that works by hooking the game loop responsible for calling world-to-screen and loads a custom vm_main function that prints an "X" over the current location before rendering the entity.

## No-Recoil
A no-recoil hack for CoD single-player that works by removing the instructions for aim being punched up while shooting.

## OpenGL-CountMonitor
A utility to log the counts of displayed entities to help isolate specific counts of player models.

## OpenGL-Wallhack
A wallhack that uses the glTexCoordPointer method to achieve great results without logging counts.
