First of all,you`ll need to find 3 hidden ancient inscriptions on the 4th,5th and 6th levels.


To get to the 1st ancient inscription on the level 4,you`ll need to go 3 down,1 right,2 down,1 right,2 up,1 right,2 down,1 right,2 up,2 right,2 down,2 right. (You also get achievement Pathtaker)

After finishing the boss battle you will be in your home with all the demon girls you`ve taken from hell. In the middle of the house lies the carpet with a pentagram on it.

Standing right in the middle you`ll need to move like this :
1 down,1 up,1 right,1 up,1 left,2 down,1 left,1 up,1 down,1 right,1 up.
If done correctly,portal shall open.



Get in it after Lucifer tells you not to.

Enjoy the ending.

I hope my little guide helped you to get 100 % of the game and have a great day :-)
