I read on a site that listed the cheats for Rage that to activate the console in the PC version so that you can then enter the cheat codes, you right-click on the game 9icon, in the Start menu, I assumed), go into Properties, then Set Launch Options. Well, there is no Set Launch Options under properties, that I could find. Can anyone help?

Activate Cheat Console and Codes

Open a text editor and type the following:

set_AllowConsole 1

Save the text file in the file in the Steam\SteamApps\Common\Rage\Base folder.

Start the game and press the tilde (~) key to open the console. Enter the following codes for the desired effect.
?cvarAdd g_permaGodMode 1 - Enable God Mode
?cvarAdd g_infiniteAmmo 1 - Enable infinite ammo

?cvarAdd g_infiniteAmmo -1 - Disable infinite ammo
?cvarAdd pm_togglesprint 1 - Enable sprint toggle
?cvarAdd g_weaponkick 0 - Disable weapon kick

You can use the following commands to add or subtract from default values. Example: The default field of view for the game is 80. cvarAdd g_fov 10 will make it 90, and cvarAdd g_fov -10 would make it 70).
?cvarAdd g_fov # - Change the field of view (Default 80)
