How to earn 1000000+ scores? It's possible on every difficulty level. Although winning depends on random. Nightmare i beat with generation of 5 police stations +3 Malls near my fort. Endless score givers: 1.Zeds killed (till cure) 2.Missions count. (even retrain leader as leader will give you score or changing bar <> laboratory or throw party)50 each 3.Food produced (very little score) 4.Happiness(50 points for each). 5.Survivors(1000 each) 6.Dead survivors(100 each) Happiness broken - when you get over than 100%(with buildings, or after electricity research), you can endless throw parties and get happiness boost. Drafting constitution somehow stop it. Strategy: math: Throwing party costs 50 food. Max amount of food depend on difficulty level. For normal it's 150 start +100 research. Nightmare 50+100. Each new day reduce score (seems by 1000). in my current game on normal i have 42 farms *8 food=336 per day. 336-250=86 That's how much people better to have for faster highscore.Unfortunally, i have 165 people.Oops, 164... 163... 1 party gives 50*20(for happiness)+1*50(succesful mission count)=1050. even with 1 party per turn your score still grow. If you want to start pure highscore game, i recommend: 1.start on comfortable difficulty. 2.you need all researches except curing zombeism 3.Make Zombieland =left them one useless for score square(bar/lab) 4.close dark portal. 5.transform all possible squares into farms. 6.now compare your food productivity with your population and food limit. 7.rounded up((food productivity-food limit)/(houses in apartments=depend on difficulty)). That's how much apartments you need. (for me on normal (336-250)/12=7.1666...=8)). Other transform into schools. 8.you need (food limit/50)*4 leaders = for max count of max parties(2 leaders) each turn(for my normal example=20) 9.other people that suitable in limit must be soldiers(in example=66)on duty=unbeatable fort 10. all left - retrain as harmfull scientists and builders and send in zombieland. 11. Now throw parties each turn, if lone gunman/radio survivors join you, you know where they must spend their holidays. each party +1k, each day-1. 5 parties per day=+4k per day PS: if you have game, where you reclaim all squares, but didn't win with drafting constitution, you can play same way. Remove apartments, population will freeze, for killing innocents = remove hospital. Sometimes "Illness strike", and you have -1. Good luck.
