heheheee 5,003,468 :D ,i still had 170 nukes left but i hit a spike, at about 3mill i fell between a land spike and a wall spike but i activated a nuke right when i was going through the wall spike and it saved me^^
3 million is pretty easy,especially if u got the 5 hour bonus(+100% cannon power),i havent got it yet but with a tank,golden gun,rocket and about 5 nukes i easily got about 2300000
