My Idea is :

A Internet in pzlinux mod you could acess a few websites !

One would be a forum

The forum would go down on day 12-19 to pretend the internet has been shutdown ! in the forum you would find people from outside world a few from brazil , russia , usa , germans and other countries

In the forum you could find :

1 -People talking
2 - People from exclusion trying to leak information
and interact with people (style npcs but the interactions are online only )
3 - Having your information leaked (if it happens a zombie horde could appear that would be people trying to get into your location could be super rare )
4 - talking could be similiar with week one mod with a few things npcs understanding and others not
5 - online chess (you could play chess with a random person from the world that is a npc you could generate random names )


Why :
Those ideas would be immersive and would give a vibe when talking with the outside world !
