Vampire Survivors has a hidden stage for players to unlock, calle Room 1665. However, the journey to unlocking this stage is an arduous one, and is a path not to be taken lightly.

How to access the Room 1665 stage in Vampire Survivors

Unlocking stage Room 1665 in Vampire Survivors is very simple… if you’ve already got access to the Secrets Menu, that is.

In the Secrets Menu, type the phrase “forbiddenbox” in the text box to unlock the new stage, Room 1665. That’s it!

Room 1665 is a terribly difficult stage, so you may need to do some grinding and serious practicing to take it on.

However, if you don’t have the Secrets Menu unlocked, then you’ve got a long path ahead of you.

How to unlock the Secret Menu in Vampire Survivors

To unlock the Secrets Menu in Vampire Survivors, you must complete the Bone Zone run. If that sounds alien to you, then allow me to take it from the top.

Firstly, you must activate the hyper mode for any three of the following stages:

• Mad Forest
• Inlaid Library
• Dairy Plant
• Gallo Tower 

To unlock the hyper mode, you must survive the stage for 25 minutes and then defeat the boss that’ll show up. Each boss will be different and pretty strong, so you may not defeat them right away. But practice makes perfect, so keep going at it!

Doing this will unlock the Bone Zone stage.

Inside this stage, you must head toward the question mark that’s on the map. You’ll find a boss called the Bone Ball, and you’ll have to defeat it, where it’ll drop the Forbidden Scrolls of Morbane.

The Bone Ball can be pretty tricky as it grows in size as it absorbs enemies, but as long as you level up before engaging, you’ll find that it’ll still be small as no enemies would have spawned around it for it to absorb. Leveling up before attacking is a must for an easier fight.

Once the boss has been taken care of, you can finish the stage, which is when the Secrets Menu will unlock.

You can then use the Secrets Menu to unlock the secret Room 1665 stage!

Now that you’ve got quite the to-do list, you’d better get a start on it. Knowing about all weapons evolutions might make your journey easier.
