Far Cry is one of our favorite games in the office. The graphics are stunning and the open-ended freedom of the game is amazing.
When I started playing, I set my pad up like a standard keyboard. As I played, I continued to modify my key placement scheme until I reached a balance of comfort and precision tailor made for my hand. I liked being able to have access to all the extra keys that you need in Far Cry for binoculars, flashlight, sprint, weapons switch, night vision, and cycle grenades.
Another cool feature was creating a macro, which switched from my existing gun to a grenade, lobbed it into enemy territory and then switched back to my machine gun ready to be fired.
