This is a static first-person view that uses negative Z Elevation to give the impression of depth. The enemies start from the end of the hall and move closer to the camera. I'm unsure how best to make it so that the crosshair lines up the the enemy position taking its distance into account. The red line is where objects are considered to be overlapping. I also have no way of making only the enemy closest to the player is shot if there are multiple taking up the same space.
