209w ago - Today TheUnkn0wn from the NGU forums (linked above) has released a Call Of Duty: Modern Warfare 2 CVAR Tool v2.0 for PS3.
This tool allows you mod your SAVEGAME.SVG file so you can have things like super jump, infinate ammo, infinate health, all weapons and much more.
This is ONLY FOR SINGLE PLAYER AND SPEC-OPS. I copied a list of the CVARs (commands) and in the screen shot you can see how you enter the CVARs. Not sure what all commands do but you can experiment with the commands and different values.
Changes in v2.0 I have fixed the 'Fix Checksum', it should now work properly.
I have modified the CVAR's in the CVAR List. Bugs that made 2 byte values create an incompatible gamesave have been fixed!
Why Release? I am the first to do this aswell as reverse the checksum myself, as I have been able to do this for quite a while. I just thought I might aswell release it as there's nothing special about it.
