How to Get Keys in the Graveyard
Mary / Bearer of Keys
In the graveyard you’re going to need to find keys in order to progress. You will need to seek out statues of St Mary, mother of Jesus. Mary will spawn keys randomly. Currently she spawns keys every 1-2mins. She will only allow you to have one key at a time. If you want another key you will have to use the one you have first.
Beware, Mary is a zombie attraction. Keys will vanish after 30 seconds so keep an eye out for them (while trying to survive).
