As you reach the final Act of Clair Obscur: Expedition 33 and return to Lumiere to defeat Renoir one last time, you will be able to restart from the very beginning of the game in NG+. This comes with a few caveats, but is absolutely essential given the many mysteries hidden in the far reaches of the Continent. NG+ allows you to play through the game once again, but everything will not be the same. Most significantly, NG+ enemies are going to be much harder to take down, and you're going to have to put each character's skills to the ultimate test.
