Sewers are tunnels dug underground to transport sewage and waste. They are dark and filthy places so making it a base is not recommended. Also, bear in mind that not all sewers are huge and roomy, as commonly depicted in video games such as Left 4 Dead and Resident Evil 2; many are small and cramped.
Advantages[]
- Securing it effectively will be a challenge, but it is possible
- They are easily found and accessible simply by opening a manhole that covers the entrance
- They allow movement through the city they are underneath with relative safety from the zombies that stumble above
- A working filtration system could create plenty of fresh water
- Large sewers can house a lot of people
Disadvantages[]
- Sewers are usually pretty dark, despite having a few lights that will most definitely stop working once the power shuts off
- Sewers are dark, filthy and full of disease
- Explosive, poisonous methane gas can linger in a sewer because of the large presence of fecal matter and other bodily waste
- Many sewers are tiny, confined spaces and are difficult to move throughout
- It has no supplies except maybe some tools that can be looted from a zombified worker
- They could already be full of zombies from a previous failed recolonization attempt
- Grates could block some parts of the sewer, making them inaccessible until the proper tools used to remove them are found
- The lack of light could cause survivors to go crazy
- Growing food will be impossible because there is no dirt or sunlight
- The only option for food is to scavenge which can be very dangerous
- Lack of food could cause panic
- Since they are tight spaces melee fighting will be difficult
