On the following page of our Devil May Cry 5 Guide, you will find a description of the third secret mission in the game.
Secret mission 03
Where to find it: Mission 04 - V
The next secret mission is more difficult to find. First of all, you have to summon the Nightmare when you're fighting with enemies, near the building with a mural skeleton. Thanks to this, you will reveal the passage after the fight, where, among other things, you will find a fragment of the blue sphere and Young Nidhogg.
Thanks to this, you will be able to eliminate the vegetation, enter the building and launch the secret mission 03.
This time the task is different - you have to collect 20 red balls in 35 seconds. Immediately move left, pick up the first 6 balls, then take 8 balls from the middle and move on to the last remaining balls. In case of problems, watch our video, which shows how to make it in time. As a reward, you will receive a fragment of a blue sphere.
