How to counter insidious basment bubba?

There is no direct counter to that, but there are some things people can do to succeed. Sorry this will be a longer text, but this method is working very well for me.

First the obvious stuff and the scenario where oyu dont have that much influence of the game: You are on the hook

• When you are the one who is geting camped, wiggle with your arms very fast and freqeuntly from the second on you are on the hook to send a signal to the other survivors. This is a code pretty much everyone understands as "camping". This should be especially clear when you verse a bubba and he put you into the basement.
• Struggle until the end to buy your team 2 minutes. This should be enough for at least 3 or even 4 gens. If someone is still trying to go for you, it is time to let go instantly before the survivor reaches you - to prevent total desaster

Its not you that is hainging down there

• Be the guy who holds the game together. First step, always be aware who the killer is. There are tons of indicators that will let you know if you are versus a bubba or not. To make this short: Even without seeing the killer, only a few killers are usually not identifiable within the first 30 seconds of the game and not seeing the killer at all. For example, Nurse, Billy, Freddy can be identified within seconds, Pig (boxes), Plague (fauntains), Clown(scream), Doctor(scream), Deathslinger(shots), Myers(T2), Wraith(Bell and cloaking sound), Legion(Frenzy), Trapper(Beartraps) or Huntress(45 meters lullaby) should be identified very likely also withing less then 30 seconds beeing in the game.
• Having this in mind if a survivor goes down due to a chainsaw and knowing it is not a billy, it has to be a bubba.
• If the survivors goes down due to 2 hits, it is either Hag ( possible but not very likely since rare killer, also if the survivor goes down within a timespan of 30-45 seconds of the game it is not very likely it is a hag since most take time to prep the map before they go hunting), Ghostface (possible but probably not, since you most likely would have seen someone beeing exposed, especially at the start of the game), Oni (definitly not, just listen if he gets his full power up after hooking the person), Demogorgon (possible, usually hard to identify right away), Spirit (phasewalking coud be heared) or Bubba.
• So there are pretty much 2 killers left in DBD you are probably facing that can be totally unknown after 30 seconds in the game. Bubba or Demogorgon.
• Having thse indicators in mind, it is always smart to go to the center of the board, so you get 2 things done: Information and one of the most important generator!
• Having all the info in mind and beein in the center of the map (as a pro you are ;) ) you will know if it is a bubba or not 99,9% of the time.

With this awareness and knowledge it is time now to use it to succeed this round when someone is camped in the basement and maybe only you are aware of it

• Do the gen in the basement building (Shack or Main building)
• This has 2 very important advantages for your team: First, the most dangerous gen is done and there is no more reason to be near the basement for your team. The killer has 2 options: He gives up camping, or he gives up his win condition generator. Usually, the killer is in a ######### position. He knows that you knows, and whatever he is doing, his plan will not succeed.
• Second: You are warning people. If they see you do the gen inside the Shack while someone is on the hook below you, there is a big chance that they will realise whats going on. You can also warn them with gestures.
• I can say from my knowledge that this works 95 out of 100 times. The killer ofc gets his 1K, but thats about it. No basement party, no uncertainty of your teammates.

I just want to enjoy the game. It’s hard to enjoy it when killers do that. I just wish they penalized them more for being near a hook 🤦🏽 At least make me feel good about sticking around. You’re lucky I’m teamed up and I like these guys because hook suicide seems like a viable option. It’s not fun.

Survivors need to make it a universal rule to wiggle your arms while on hook if the killer is camping. If I know its a Leatherface I don't even attempt to go near the basement unless i know he is in a chase.
