This doesn't even deserve 3 stars, let alone whatever miracle made it end up with 4. This is basically the same p2w garbage that happened to learn to fly, though this game somehow manages to be twice as dull.
This hard badge might as well be impossible considering you need a godlike start and a couple dozen lucky coin flips to even stand a chance against the literally random battles.
Anyway, some tips I found are that
A) Churches will always be safe (at least during the first 3 turns) so if you start next to one, send your leader immediately.
B) Making a beeline to a corner of the map isn't always the best choice, since rural areas (farms, trailer parks and graveyards) spawn on the right side of the map, and urban (apartments, malls and rubble) will spawn on the left, so if you're going towards the right consider grabbing a couple houses first, if you're going to the left get some farms otherwise you'll starve by turn 5.
C) The game is basically an excesively long dice roll, so if you get a bad start don't be afraid to reroll and try to get something good.
Good luck!
If you're having trouble with the timed badge:
1)Don't be afraid to restart until you get a good alignment of tombstones!
2)You can hit his forehead when he does the lazer attack from the left, but not from the right, since the platform isn't high enough, you must attack him from behind.
3)While he is becoming a skull, go and hit the (hopefully) 4 tombstones you've rounded up in the middle of the arena, you'll become fabulous during an otherwise useless time.
4)Defeat his first phase on a corner of the screen, go grind up your level and come back as soon as he becomes vulnerable, he is unable to sprint as a skull, and you'll be able to stun-lock him.
Hope that helped with your troubles!
