killer idea
ninja killer that can jump and cling to walls. once he is on a wall, he can throw a shuriken. once thrown, he goes back to his original position. with red addon you can jump 1 more time from one wall to another.
this could easily be achived by using the wall-detection, that singularity uses for his cameras.

and also with addons you can improve the amount of shuriken needed to injure or how many you can throw before he goes back to his position.
