You are currently in an old warehouse on the outskirts of Gotham because of the previous time in the Batcave while you were messing around with your computer you saw that the Joker had just appeared in the area, Because you don't want to disturb the others who are on patrol, you end up going there alone..

You look around and don't see any signs, but when you want to go out and are already at the door, you feel like something is lurking inside you, you try to look around again but there is nothing then you see something on the floor.

When you approach it, it turns out to be a card, you feel when you enter there is not a single card on the floor except one.. you are not alone..

You look around again quickly while trying to contact the others but suddenly you get hit by something behind you and when you turn around, You froze when you saw a figure that was none other than Joker himself..
