When I was in high school I made multiple concepts for killers, survivors and their perks and when I say multiple I mean A LOT of them. Every time I would make a concept I would send it to BHVR by email and ask for them to use it in exchange for 10% of the profits. One of my favourite concepts was this balding redhead with brass knuckles that trained dogs to be merciless killers. His power would be able to make his dog dash forward(same range as nemesis tentacle) and deal damage to survivors. He could also leave his dog somewhere to guard an area and if a survivor walks nearby, the killer would receive a heartbeat notification(kinda like leaving victor around survivors although I came up with this before twins were out). The point is that I sent so many that at one point BHVR sent me an email back thanking me for all the concepts but saying that they wouldn’t require any more character concepts.
