managed to do 4 basement sacrifice!

[demonofshoes]

map i won on was coldwind farm, the one with the toppled silo. had it twice in a row and both times had 3 gens close to each other next to the silo and the basement within so you can stall the game by having a tight patrol of those 3 while having easy access to the basement. best to use a one shot killer like bubba to get easy downs. if a survivor tries to get you to chase them far away from these 3 gens follow for a bit then return quickly. if you are lucky that survivor was meant as a distraction and you can find another on the gen you just left.
perk wise territorial imperitive is a must. you need to see if anyone goes down to basement either for the chest or for an unhook. survivors have a task to open a bunch of chests so they are more likely to go down there to grab the basement one. if you see coins in the offerings they are likely on that task. you can use agitation and iron grasp to have a larger margin of error for distance but if you manage to keep those 3 gens you shouldn't need them.
try and get a down asap around the basement. i find a play with your food and nemisis perk build gives bubba the speed to catchup to any survivor quickly with his chainsaw, especially with his quick charge addons. try and keep 3 stacks of pwyf till the chase moves to basement area. if you can try and remove as many pallets around the basement to make chases later a lot easier.
insidious can also be used as well to camp the basement and get people going for unhook (i know it's a cheap tactic but this task makes it a bit nessesary). try and get at least 2 sacrifices down there before moving to next phase.
if you can down second last guy and he's not on his first hook, hold off on picking him up. if enough gens are done try and find the hatch spawn. if the last survivor gets this then you have to do everything all over again. when you find it go back for downed survivor and try and hook him. if you are lucky the last survivor might be there doing a heal and you can get a twofer.
if not hightale it to the hatch to close it and patrol the gates. try and get a chase that goes to the basement for that last hook if possible but hopefully the last guy might just give and let you carry him without a struggle. one unfortunate thing you will have to watch out for is disconnects which can completely negate your progress.
hope this helps anyone else on the task. others that have done let others know your stratagy

This will be easier because the DC penalty.

[demonofshoes]

dc penalty trial is only until 19th december, 11am et and even then, if you get a swf group can easily see them DCing just to spite you for killing one of their friends. also no vid i'm afraid. don't record. and besides there is a lot of time when nothing exciting is happing. the whole game will take a while once they reliese that they have 3 gen-ed themselves and there will be a lot of tapping and running away. think first match was close to an hour and then last person got the hatch (hence the warning in the instructiions). second was near 45 mins i think.

Well, the first match went well, I didn't read your bit about slugging the second to last survivor, it works though. I 4 gened them and got the 3k but one got the hatch.
