This is the first story achievement for this DLC, the third quest in the chain.
* "Welcoming Committee"
- Recalibrate the 3 defense turrets to shoot zombies.
* "Is The Doctor In?"
- Go to Doctor Ned's waterfront clinic.
* "House of the Ned"
- Go to Doctor Ned's house in the bayou. You will have to fight through many, many zombies to just get there. When you speak to Dr. Ned over the intercom, there is a Left 4 Dead
style crescendo event where dozens of zombies will spawn while he hand-cranks the elevator down. Kill them all and go up the elevator, then speak to the doctor to get the achievement.
There is a medical vending machine in his house, a good time to sell your surplus items.
The ahcivement name is a reference to Sega'sThe House of the Dead
arcade game series.
