This patch updates Truth mod v1.0 to v1.1. To install it, overwrite your my documents/my games folder with "my games" folder in the archive. Do the same with Widescreen Fix/my games folder if you want to play in Hor+ mode. Fastest way to access your "my documents" folder in Windows Vista or 7 is to click the blue button with Windows logo on the taskbar and then click the "Documents" word. If you don't have Truth mod v1.0, you need to download the whole Truth v1.1 release.
