The Halloween Event is a seasonal event in Shell Shockers that occurs every year in October in celebration of the holiday Halloween. During the event, limited-edition spooky-themed stamps, hats, and weapon skins are sold in the shop to celebrate Halloween. During this time, the map 'Haunted' is also added to the public map pool. This event comes in every year at the same time, although not all the skins are always brought back.
