So essentially 4 VT, while every mafia had a power + an arsonist and no fire fighter. Town was pretty much doomed from the beginning. Though I must say, people should have wondered why brett was killed at night, since all it did was "confirm" Cyber as town. There was no reason for them to do this since it behooves them to have people confused and wondering who is telling the truth, and since many thought that Brett and Cyber were mafia to start with, it would have made sense to keep them both alive. In addition to the fact that everyone assumes brett is mafia, and he is terrible at playing town, there was no reason to kill him.
Overall though, town was kind of fucked due to being outmatched by mafia and 3rd party powers, it also doesn't help that there was a severe intelligence deficiency on the Town's side, especially given the power roles they had.
