I got an Idea not really Halloween related but they could do baddy kill rooms 1k,5k, 10k?
with like little shop and new farming part...
Now for Halloween:
(NOTE MAY HAVE BEEN SAID-more who say the more chance of happening)
- New Event place where one person starts of infected and the others have to keep not infected whoever is last to be infected wins prize(gralats?)
- Like the Easter egg hunt maybe do one but finding pumpkin [then you could update the memorial place like it said it was going to be(after fireworks on the sign[got deleted]) but didn't.
-A zombie that hide in different places [limited time](gives hat or head if found)
Lastly maybe a little quests to give us an insight of what the quests are going to be like on iPhone server [remi said quests and lava-land he expects to come near Christmas time]
