Game Killer is a free Android app that lets you use cheats and modify aspects of your favorite video games. It works by injecting code from the background while the game is running, letting you modify whatever values you want in the title in question.
Once the app is opened, it stays open on your device and is accessible from a semitransparent icon that you can place on any part of the screen. You can access Game Killer whenever you want and select the game from the list of running services.
From the built-in search feature, find the number that corresponds to the parameter you want to change. A good example is available lives. Once you've determined the position of the parameter you want to change, all you have to do is enter a new value and make the modification.
Game Killer is a useful tool for gamers looking to use cheats while playing. (Keep in mind, though, that there is sometimes a risk of being banned.)
