How It Works

A protected BSP file and it's acompanying LMP file are carefully stiched together at a specific binary offset to reform an unobstructed .BSP. This ubobstrcuted .BSP can then easily be decompiled and played while the protected .BSP cannot be decompiled, lacks entities and may even crash the game.
