Cheat Engine(wiki), commonly abbreviated as CE, is a free memory scanner/hex editor created by Eric "Dark Byte" Heijnen for the Windows operating system. Cheat Engine is used for cheating in computer games, and has influenced many, as it is often modified and recompiled to evade detection. This program resembles L. Spiro's "Memory Hacking Software", Tsearch, and ArtMoney. It searches for values input by the user with a wide variety of options such as "Unknown Initial Value" and "Decreased Value" scans. Cheat Engine can also create standalone trainers that can operate independently of Cheat Engine.
Cheat Engine can view the disassembled memory of a process and make alterations to give the user advantages such as infinite health, time or ammunition. It also has some Direct3D and OpenGL manipulation tools, allowing you to see through walls, zoom in/out and with some advanced configuration allows Cheat Engine to move the mouse for you to get a certain texture into the center of the screen. This is commonly used to create Aimbots.
Cheat Engine can inject code into other processes, but doing so typically causes anti virus software to mistake it for a virus. There are versions that avoid this false identification at the cost of many features (those which rely upon code injection).
