The Bone Zone is the second Challenge Stage in Vampire Survivors that players can unlock after gaining access to the Green Acres. The Bone Zone does not contain any Pickup drops, but it does feature the Forbidden Scrolls of Morbane, a Relic that enables fans to access the Secret Menu and gain the ability to cast Spells. Additionally, this Relic is required to unlock the Eudaimonia Machine, a final stage where players must face the game’s final boss. The Bone Zone Challenge Stage is also where Gains Boros, a hidden character, can be unlocked in Vampire Survivors.

Unlocking the Bone Zone in Vampire Survivors

Unlocking the Bone Zone Challenge Stage in Vampire Survivors is the same process as gaining access to the Green Acres. The Green Acres requires players to unlock Hyper Mode for two Normal Stages before it becomes available. Likewise, the Bone Zone mandates three Normal Stage Hyper Modes to be obtained.

For those unfamiliar with Hyper Mode in Vampire Survivors, the Vampire Survivors Wiki states that it is a variation of a Stage that improves the player character’s and enemies’ movement speed, projectile speed, and the number of enemies spawning. As a result, the pace at which player characters will gain XP and level is significantly increased. Players will be able to become stronger much quicker, but the Stage will be more chaotic with increasingly more formidable enemies. To unlock Hyper Mode for Normal Stages in Vampire Survivors, players must accomplish a specific prerequisite.

The easiest way to unlock the Bone Zone in Vampire Survivors would be to fulfill the Hyper Mode requirement for the first three Stages of the game. The index below describes how Hyper Modes for these Stages can be unlocked: 

If players wish to instead unlock the Hyper Mode for Gallo Tower or the Cappella Magna, a challenging foe will similarly appear at the 25-minute mark for both of these stages. Accordingly, slaying this particular enemy will unlock the Stage’s Hyper Mode variation.

  • Defeat the Giant Blue Venus, a boss that spawns on the map at the 25-minute mark.

  • Defeat the Hag, a boss that spawns on the map at the 25-minute mark.

  • Defeat the Sword Guardian, a boss that spawns on the map at the 25-minute mark.
