The Crash 4 N. Verted mode is unlocked around halfway through the story, after beating the Trouble Brewing boss fight level in Tranquility Falls. This setting allows you to revisit all of the core levels in the game while dealing with quirky effects to add an extra layer of difficulty, on top of the fact that the stage has also been mirrored. Although you don't have to beat N. Verted levels to progress through the story, they do feature plenty of collectible items as well as exciting twists, so you shouldn't overlook these experiences. If you want to know how to access N. Verted mode in Crash 4 and what it changes, we've got you covered.
Crash 4 N. Verted mode explained
Crash 4 N. Verted mode essentially takes the familiar levels you've played before, and mirrors them. Not reverse, but instead everything is literally flipped horizontally. This means that nothing should come as a surprise when you're exploring the levels that you've previously beaten, but it will take some getting used to.
But that's not all; N. Verted levels in Crash 4 also completely change the art style. Some make it much harder to play – both N. Verted levels on N. Sanity Island have a pulsing vision so you can't see very far ahead of you, for example – while others just alter the effects, like applying a cel-shaded filter to what you can see.
N. Verted levels also replace all Wumpa Fruit with Bumpa Berries, replacing the apple-esque red collectibles with what are essentially purple grapes. For all intents and purposes they're the same thing, but there are certain trophies and secrets linked to Bumpa Berries.
Finally, while crates and enemies are in the same places in N. Verted levels, Crash 4 hidden gems are not! This means you'll need to hunt all the way through each level again if you want to find all of the Crash 4 N. Verted hidden gems, because they've moved into even more difficult to find locations. Good luck, Bandicoot!
