Bluedog

This server is a week long survival event set in an Attack on Titan style world. It uses a huge custom dimension and you spawn into different villages spread across the map. You start with some basic supplies plus a set of ODM gear and there are horses for getting around.

The big thing is there is no global chat. Talking only works with proximity voice so you have to be near people to communicate. It makes everything feel tense because you never know who is close by.

On day 2 five random players secretly become Titans and they look like normal players. Their goal is to kill everyone and stop survivors from escaping the dimension. Every in game day ends with a vote where players try to figure out who is a Titan.

There are lots of places to explore like villages forests rivers dead zones and even a beach at the edge with a sealed portal. Titans also roam the wild so even traveling can get scary.
