Instructions
Launch the "Unreal Tournament" game on your desktop or laptop computer. Start a match in any game mode except the online mode.
Press the "tilde" key (~) on your keyboard, which is located under the "Esc" key and above the "Tab" key. A text box should appear in the upper right corner of the screen.
Type the word "god" into the text box and press the "Enter" key on your keyword to submit the code and return to your game. The "god" code changes the default settings and prevents you from sustaining any damage during the game.
