Having enjoyed the recently released Ghost Recon: Advanced Warfighter 2 Multiplayer Demo, I've put together a GRAW 2 Tweak Guide which covers all of the game's settings in detail, as well as providing advanced tweaks and gameplay tips. The guide will be updated when the full version of the game arrives later this month, but for now I encourage all GRAW 2 players to give it a read through as it likely has something you'll find useful.
