I still remember how a few years ago I played on the computer - a long time ago since I switched to consoles - and used the classic Trainers when I got bored, which were nothing more than variable modifiers to change game parameters.
The Cheat does the same in a generic way, allowing us to change the values of certain game variables to increase weapons, their ammunition, the number of lives or whatever we want.
The truth is that the great thing about this app is that the limit is not defined, but it goes with each game and with you.
