Sorry my english. In the future of game, little quests can be implemented to catch special loots. I thought one that it's a type of trap. The Castles are really scary on night, so in this time, would open a door next the castles, that will take to underground, when someone enter on it, they can't get out for the same way, so they have to pass for alot of zombies to go till other door in other side, where will be the special loots, to avoid the steal of another players in the out of quest, that underground would be 3 sides (ways, path) to get out, so it make more difficulty to know where the people gonna out of quest.
