U can hack it with game guardian i did u can hack dmg and health u have like one hit kill more health and i also use the mod apk to and i did get warning when i was lvl 10 now i am lvl 16 no save and i am still playing no ban yet but some far way missions not the first 3 or 4 land in the map work good when i reach land 5 or 6 it use game guardian or mod apk even if u win doesn't register it that u win its a glitchy but some time it will work.
And for the ppl asking for UnSigned apk u don't need to download the mod just download the play store apk and use game guardian if u have root or if u don't then use the virtual app if u want to use ur account my main account i use game guardian i have root and for the mod i use it in my ipad not root i have 2 account.
Enjoy
