"The Guise of the Colossi," the first of these add-ons, lets you transmogrify armor into six freaky, human-sized avatars based on the monsters from Shadow of the Colossus. It's unclear if these armor variants will also make Diablo's enemies feel horribly guilty about killing you in battle.
Alongside the Colossus tribute is "The Last of Us Nephalem Rift," an entirely new dungeon stalked by Clickers and other mushroomy infected enemies from Naughty Dog's apocalyptic adventure. It's also unclear if this dungeon will find your avatar rediscovering what it means to love and care about people.
Digital pre-orders also come with some non-Sony themed perks, including three extra character slots, "Infernal Pauldrons" shoulder gear that boosts up stats right at the beginning of the game, the "Liber Canis Mortui" scroll for summoning up a hellhound companion, and the Arma Haereticorum and Arma Mortis, two sets of recipes for transforming your weapons and armor into other fancy shapes.
