You will need:
• USB Flash Drive
• USBXTAFGUI (for USB)
• Modio
• List of DVARs
1. Get your flash drive and put it in your Xbox, once its in then go to System Settings> Memory> Modern Warfare 2 and move/copy the savegame file from the Xbox to your Device.
2. Once its copied to your device, take it over to the computer and open up XTAF. Rummage through the directories until you see a savegame.svg (assuming that you have no other saved game on your device other than this), then extract that somewhere to be used in Modio.
3. Now that the savegame.svg is extracted, Open up Modio and drag the savegame file inside once Modio starts up. There should be quite a bit of options, but our main concern here is to mod the file so you should obviously click "Mod File". Once there, click the far right tab which should say dvar(s).
4. Go fetch some dvars that may interest you in this game specific to MW2 (because there are also dvars for other cod games too lol).
e.g.
bg_softLandingMaxHeight "5000"
bg_softLandingMinHeight "1"
DVARS are here

5. Save the file, rehash and resign, and exit modio once your finished selecting your dvars. Go to your XTAF, DELETE your previous gamesave and INJECT the new one it its place.
6. Once done, take out your USB and rape some russians in campagn/SpecOps
