HYDRA SMP is a new survival multiplayer server that is starting out with only a few people. It is meant to stay small so it feels less overwhelming and it is easier to actually become friends.

The server plans to go semi private once it hits around 15 members. After that it sounds like it will not take many more people so it stays fun and tight.

Rules exist but they are not super strict. Still you are expected to follow them because breaking rules can get you banned especially if you join without reading them.
