well guys a lot of you probably know this but ima talk about what is called the fish bowl.
what you do is go ingame with 8 friends or 8 ppl who know what fish bowl is (if you going with strangers i reccomend naming it "fish bowl")
on the east side (i think) there is the burnt down barn building thing. have 3 ppl on the porch aiming at the zombies coming from the barn
have 5 ppl stay in the hallway behind the wall in the kitchen area. ( the wall on the right in the picture below.)
by staying behind this wall it will make all the zombies that come into the building to walk, instead of sprinting at you. that way you have more time to pic them off.
give me thanks if this helps at all (:
