Cheating hack

Cheating is any modification not normally available in Doom which provides an advantage to one player over another with regard to:


 * humanly-executable player movement,
 * visual abilities,
 * audio abilities,
 * player aim abilities, or
 * mechanisms to locate the opponent,

These changes are put into effect in a game against another player who either


 * does not agree to, or
 * is unaware that the change has been implemented

Modifications to sound and graphics to help a hearing or visually impaired player compensate for his or her disability are usually not considered cheats.

A number of methods exist for cheating within Doom:


 * Aimbots
 * Map editing
 * SR-50 automation
 * No red
 * Full brightness
 * Sprite editing
 * Sound editing
 * Red dot
