So Poppy Playtime has an early access 1v6 asymmetrical game
I just learned about it today. It's called Project: Playtime. I'm watching someone play it and I just wanted to talk about it since there's some interesting things the game does over DBD.
The survivor team has to solve these boxes which contain 3 simple mini-games. If the killer interrupts someone in the middle of doing a mini-game the progress is reset for that mini-game. Personally I kind of like this objective system, because there's more reward for interrupting the objective while also not just being a hold button for a long duration. Once you complete the minigames you get an object to deposit to create a toy. Once the survivors finish 3 toys, they can call the train for escape. I also believe if there's 1 survivor left, the train automatically comes as sort of a hatch mechanic.
Survivors take 3 hits to down and don't seem to have any way to regenerate health. Some areas slow down the killer, there are also doors you can pull off to temporarily close the path. Once you get downed the killer drops you into a hole and another survivor has to extract you. Killers can technically camp the holes for extraction, but since the only instant down mechanic I know of is being grabbed out of a locker, it's possible to extract someone while being attacked. There's also a limit to the number of times you can be "hole'd" so you'll die if you go down too much.
