The phrase refers to a specific type of downloadable content for the Java Edition of a popular sandbox video game, often themed around the autumnal holiday. It generally involves a collection of cosmetic changes, such as character skins, texture packs altering the visual appearance of blocks and items, and potentially new music tracks, all designed to evoke a festive, spooky atmosphere. An example would be a downloadable package containing zombie-themed character outfits, cobweb-laden block textures, and a haunting musical score.
Accessing such downloadable content provides users with an immediate transformation of their gaming experience, allowing for immersive celebration of a particular holiday. These additions can foster a sense of community and shared enthusiasm amongst players. Historically, these themed content packs have been a popular method for game developers to engage with their audience and provide ongoing value to existing game owners, particularly around seasonal events.
