I have searched on the forums, and found that there are some of these topics around but they are locked. I know that people would be aware that there is a request for the "Hidden Gun", "The Hang Glider", etc.
I don't know how the hidden gun may work as there is just a floating hand on the BL player, lol. To make the tunic for the player model it would be a chest item, and for the hood it would obviously be the head item.
The hang glider would basically just be a remodified version of the original Hanglider. Some weapons from the AC series.
I had a recent idea about being able to call other Assassin's, and use the "Arrow Storm" in BL.
