To find this mission, during Mission 15, go back to the area with the spikes at the beginning of Mission 14 and check the picture of the skull on the wall.


In this Secret Mission, you have three Shadows to kill. They will come at you either one at a time, or all at once. Which pattern you get is pretty much up to luck. Standard Shadow tactics still apply, but the close quarters may cramp your style. If you have Nightmare-β the small space might be a slight advantage with all the ricochet. If not, stock up on 5-6 holy waters, they will expose the shadows cores instantly for an easy win.
