Wouldn’t even need to add friendly fire, just bullet collision with the horde. I mean I can’t fire through the fat ogryn boi that decided to step in front of me. Why should the heretic be able to fire through a whole horde of poxwalkers and hit me?
Friendly Fire would maybe be a bit too much.
What i meant was simply that the On-Kill effect is ours, that we can take out Enemies with a killed Flamer, a killed Bomber
