Since release and Christmas is coming up, I suggest adding a Christmas-themed event.
Make a sleigh with a zombie-Santa dressed in red/white clothes and a few deers fly around the map and drop Christmas packages at player locations.
My suggestion is to trigger this event at peak player hours.
There are multiple benefits from this:
- Christmas-spirit in DayZ
- Fun experience for everyone
- Free themed items to players
- Peak player numbers will rise
- This kind of event wouldn't require huge development resources
Since this could reveal the location of other players, dropping presents once a day can be enough.
