Config files are located in "Documents\My Games\the-haunted-hells-reach\UDKGame\Config"
To fix the FOV
FOV settings can be found in "UDKGame.ini". My settings are as follows but you may prefer something different.
To Unlock the framerate
change both instances of "bSmoothFrameRate" to false.
The depth of field effect is quite overdone in this game, so you might want to turn that off too, in "UDKEngine.ini", change DepthOfField=True to false
You may want to set these files as "read only" once you have all in game settings to your liking as I've had them reset to defaults before.
