What does it mean when it says the final battle was usual? Twice now I've won the battle at year 50 and had it tell me nope, have another battle in year 51. I don't mind as such, I'm just wondering why there is sometimes a second final battle.
In survival, there should be a counter for how many kills are by enraged zombies. I managed to enrage 3 or 4 bosses, who then went on to destroy what must have been hundreds of zombies.
There is a way to get infinite amounts of fighters:
1) create 4 fighter bays with max fighter numbers and build rate
2) Wait for all 12 fighters to be produced
3) Sell all fighter bays
4) Repeat steps 1-3 until you have as many fighters as you want.
You will however need a lot of money
