In this world on a completely random day, the internet stopped, the lights didn’t turn on, power plants exploded due to the sudden blackout... The world turned into a complete anarchy, people killing themselves thinking it was the end of the world... It wasn’t, but they turned it into one.

There was no more government, there were no more laws, it was each one for himself, there was no conventional electricity (only if you made your own), internet? Say goodbye to that too. Food? Go hunting or farming, beware of looters, don't trust anyone, find your own band or form one.
