Facing off against a nearly dead siren, aim my shotgun at the open space between the siren and my shotgun soldier who I’m pretty sure he’ll go for. He goes right up the centre of the cone. Ground level, even height, no obstructions.
Dead centre.
My soldier does not fire. Proceeds to get skewered. This does not work as intended some of the time and considering how bad you get punished when you don’t take a shot, that makes it hard to use.
