Dota 1 maphacking taught a generation of gamers about "game sense." Ironically, because hacks were so common, top-tier players had to develop an almost psychic ability to predict ganks just to keep up with potential cheaters.
In a standard game of Dota, the "Fog of War" hides enemy movements unless they are within the sight range of your units, towers, or wards. A maphack is an external third-party program that modifies the game's memory to reveal these hidden elements.

Maphacks functioned by "patching" the game’s memory addresses to tell the engine to ignore the instructions that rendered the fog. 2. Memory Offset Patching

For over a decade, the battle between maphack developers and the community (and eventually Blizzard) defined the competitive experience. Dota 1 maphacking taught a generation of gamers
