so annie and mason is on mission 1 go left past annie and knock down the barrier it takes some work but it does happen. Keep talking to the people there and annie will come and start the scene.
Jelly haileys a bit more difficult. For shopkeeper you gotta lead her back up to where the shop is. Its has to be quick because she dies quickly on surface for the others you have to have the gold gate open lead a jelly through the wall near special zombie theres two for him just let him pair with jelly hailey twice. The other is same area but with mason. I hope this helps.
