Prologue, is the first mission in Devil May Cry 5. In this short mission you will lead Nero and learn the basics of controls and initial storyline events in the game. Here is a walkthrough on how to complete the mission:
Controlled character: Nero
Date: 16 May, 08:06 PM
After the cutscenes, you will take control of Nero. Run in front of you and become familiar with the controls. After a short time you will meet your first enemies - Empusa. Your enemies are very weak and will rather be used to test your first combos. You'll continue to fight an airborne type of enemies - use a ranged weapon to shoot down enemies.
After the cutscene, run ahead and fight the next pack of empusa. At the end of the path you'll see Dante fighting an unknown enemy - move towards your companion. After the cutscene, you'll face a boss fight. However, you will soon find out that your attacks are not able to threaten him - no worries, the game requires you to lose a duel with the enemy at this point of the story.
After the short interlude, you'll find out that the enemy you've met is the King of Demons - Urizen. After cutscenes you will finish the mission and get the appropriate rank, which includes the number and quality of combos, the speed of completing the mission, and the amount of damage suffered.
