This can be done a couple of different ways, you can either bind a couple of keys before you play the game or you can access the game's System Console while you play. To bind the keys, open your game's folder and locate the system folder, now locate your User.ini file. Open the User.ini file using either wordpad or notepad. Next, locate the line "K=". After the = sign type CheatPlease (it'll look like this: K=CheatPlease). On the line "G=" type God after the = sign (it'll look like this: G=God). Close the User.ini file and enter your game. Start a game as normal, while your playing you can now hit the K Button to enable the Cheat Mode, hit the G Button to enable God Mode. This'll mean you're now invincible. You can hit the buttons again to disable these cheats. This can be done another way also, instead of editing your User.ini file you can hit the TAB button during gameplay to access the game's System Console. Once you've accessed the console type CheatPlease. This will enable the Cheat Mode. Once you have done that you can access the game's System Console at any time during the game to enable certain cheats.
