The Crash 4 N. Verted mode is a wild and wacky take on all of the core levels in Crash Bandicoot 4: It's About Time. You don't need to complete all of the N. Verted levels to beat the story, but they do add exciting twists, so it's worth playing through some of them. If you're confused as to what the Crash 4 N. Verted mode actually does, we've got all you need to know right here.
Crash 4 N. Verted mode explained
N. Verted mode essentially takes the levels you've played before, and mirrors them. Not reverse, but instead everything is literally flipped horizontally. So nothing will come as a surprise when you're exploring levels 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 turning cel-shaded.
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, hidden gems are not! You'll need to hunt all the way through each level again if you want to find all of the hidden gems, because they've moved. Good luck, Bandicoot!
