This map is incredible. A fan of Arkham Asylum myself, you have paid incredible attention to detail, making an awesome creation where vents spiral around the complex and a game mode which accuratley portrays the weakness of the Batman. I am trying to make a Silent Knight map myself, from scratch and not a replica, a new creation, and could use some help in finding how you got the floor vents to be level with the top of the double boxes. If you can help, let me know.
Perfect map, fun gameplay causing people to use really good tactics to win. The only two changes I suggest involve the gargoyles: They aren't gargoyles! At least, not yet. Add some horns or something. Ghost merging and interlocking are popular for a reason! In the game, it's much easier to get to the gargoyles then how it is now. Oh, also, have you tried changing the gametype to infection and deleting all the spawn points?
