I found a small server called 30Timers and it feels like survival but way more chaotic. Every 30 seconds you get a random item. Sometimes it is trash and sometimes it is super rare so you never know what is coming next.
They also built custom systems around it. There is a custom mineral called Chronium with time themed powers. A full armor set can randomly dodge hits and the sword can sometimes hit twice so PvP gets really unpredictable.
There are no land claims here so bases can be raided and griefed if you do not defend them. To help with that you can buy turrets in the shop. The shop offers change every in game day.
The main world called Space uses a custom generator with floating islands. Mines also regenerate ores after they get mined out. The server is in alpha so bugs can happen and they want feedback.
