A type of hack used in computer games such as Counter-Strike to exploit the terrain of the arena. Wallhacks come in many forms, but they all are pieces of programming designed to give an unfair advantage to the user, usually a teenage script kiddie. Among known varieties of wallhack are "Ghostmode" (the ability to walk through walls), "Railgunning" (the ability to shoot through walls), "Glassworld" (the ability to see through walls), and many more. Because of the nature of online gaming, it is highly likely that wallhacks will continue to flourish, as for each one found and destroyed, another variation is created.
When POProdigalSon turned on his wallhack, he got an easy kill on DragonLord by shooting him through a hill.
