I've been able to mod my game save on Modern Warfare 2 successfully via USB drive. I modded it with Modio, checked the usual boxes such as speed, jump, sprint, infinite health, etc., and found an old MW2 Spec Ops save with a long list of DVARS that I added to the save. The speed, sprint, jump, infinite ammo, and other certain mods work in the Campaign. Infinite health is not one of the mods that works, which isn't that big of a deal, mainly because the max health appears to be larger, but also because you can usually just jump up to safety. Once I've infected myself in Campaign mode, I move onto Spec Ops, and pick a random mission. Now only the jump mod seems to work, nothing else. I've tried clearing system cache on the USB drive, and I've tried modding multiple fresh game saves to see if that works to no avail. Have certain DVARS been patched on Spec Ops? Or could I possibly be doing something wrong that I'm not aware of?
