An Ultimate Box comes prepackaged with all the items for that Series including all five Feature Films, every single detailed miniature, plus all of the add-ons and promos. Some of the contents will vary between different Series (for example, the Series 1 Ultimate Box will come with a Final Girl Core Box, while the Series 3 Ultimate Box will come with a placeholder to store a special feature film), but each Ultimate Box will generally contain the same amazing treasure trove of horror gaming goodness, and at a greatly reduced cost than if you purchased everything individually at retail
