So, i've enclosed off every area except one warehouse somewhere in the middle. This warehouse is completely surrounded by fortified buildings yet the number of zombies keeps on rising. Assuming that the zombies aren't having sex, there is only one other logical conclusion: some douche is airlifting the zombies in.
Best feeling ever: When you've just fired your super bomb group and everything lays in ruins. However, the game shows one person still left alive but you can't find them. Then you just see them falling from the top of the screen and die on impact. Awesome.
So, i don't know whether its a bug or not, but there is this item called 'undefined' that i sold and know i have infinite money. The icon for it is every other item fllashing through in succession.
For anyone finding it hard to complete the last level, i reccommend disabling your mitochondria and clooecting glucoses till you have at least 50 fatty acids. Then simply keep clicking toxin release and after some delay you will be spit up and will not have to fight the viruses.
