This page in our guide to Devil May Cry 5 contains a walkthrough to True Power, the last mission in the game.
Controlled character: Nero
Date: 15 June, 04:27 PM
Nero has unleashed his full power and now confronts Vergil. This fight is very similar to the previous one - Vergil uses the same attacks as before.
Nero can stay in Devil Trigger as much as you want him to. Use this to your advantage. In DT form, you regenerate health and deal more damage. Keep attacking the boss. At some point, the game will inform you that you can grab enemies to perform a special attack.
Keep fighting the boss - remember to use dodges, grab him whenever you get a chance, and look for openings in his defense. Win the fight, and you will beat the game... watch a few cut-scenes and the credits.
In the credits section, you play as Nero and then switch to Dante. Kill enough demons to unlock two secret cut-scenes. Wait for Nico's and Vergil's comments to know how well you did. If they weren't happy with your performance, replay this part!
Congratulations, you have completed Devil May Cry 5!
