Short Guide on How to Unlock the Secret Character MissingNO in Vampire Survivors.
To unlock MissingNO, you will first require the Yellow Sign relic. If you haven't got it already, check out our guide on How To Unlock Yellow Sign.
Enter the Green Acres stage with hyper mode and hurry mode enabled, preferably with a fast character like Red Death. You will need to head 18 tilesets west and 18 tilesets south, so start walking diagonally toward the bottom left corner of the stage. Once you reach your destination, the stage's appearance will start to drastically change, and giant winged eye enemies will begin to spawn. All you have to do now is kill 128 of them, and afterward, you will have the character MissingNO unlocked.
If you prefer, you can unlock MissingNO using a cheat code. Simply access the Secrets menu, which you can find in the main menu if you've unlocked The Forbidden Scrolls Of Morbane. Then, enter the code 'rightninetyseven' and you will have MissingNO unlocked.
