How to Change Field of View
Prey will support CrossFire and SLI, as well as offer ultra-widescreen support at 21:9 at launch for PC players. FOV can be adjusted via a config file and will be accessible via the Options menu in a coming update.
To enable FOV, edit the game.cfg file in notepad. The file is located in the root Prey folder in your Save Games folder (likely c:\users\\Saved Games\Arkane Studios\Prey )
Look for cl_hfov = 85.5656
85 is the default horizontal FOV setting, but it can be replaced with values up to 120.
