CoSMOS Gamehacking Tool

Hi hope you are all doing great
this game called tankblitz can not be easily altered as values
i can not change the value of any item: ammo, health, scores, anything.
i used cosmos and CoSMOS
with cosmos i got the address but can't change the value as it marked as ??

any idea will be appreciated with how to deal with this kind of ?? trickery !!!

Good luck
