Sounds like a dangerous place :3 

As for tech level, it will be the same as IRL tech level. However, because of the poverty and crime rate of the city, local technology seems 20 years behind; so laptops, smart phones are not a common knowledge to the local inhabitants. You may have brought in modern items (electronic devices) on your own if you were from the other cities, or if you are rich and have connections. Law enforcement is not possible too; so people take ownership of abandoned houses (or suspicious dens ;3) on their own account. 

Side-note: looking for around 5-10 people taking interest and I can put in more details. xD
