Many different PC games contain Easter eggs, cheat codes and even bugs which are activated by certain resources and key combinations; other games don't have known cheats which can be activated without a trainer or a program like Cheat Engine.
The main purpose of Cheat Engine is to allow for complex modifications of the system memory to achieve in-game tricks.
This program has many different functions which modify the system RAM and even includes tools for Direct3D and OpenGL. By changing values with Cheat Engine, you can do things like see through walls or move around maps without hindrance.
If you like playing around with games or have gotten bored of playing the same old game, then Cheat Engine is a great way to add to the lifetime and replayability of your PC games.
The web site of Cheat Engine includes many known cheats.
Installation note: During the first few steps of installing Cheat Engine on your PC, you may be asked to install 'additional offers', all of which are unnecessary and we recommend declining.
Cheat Engine is licensed as Freeware for Windows (32-bit and 64-bit) operating system / platform from action games without restrictions. Cheat Engine 6.2 is available to all software users as a free download (Freeware). Though marketed as 'freeware', Cheat Engine actually includes adware or something which resembles adware like toolbars or browser modifications.
