We have just released new events to the server, Blood Moon and Animapocalypse. These events add more to the survival aspect of the server and are really fun!

Animapocalypse:
All animals temporarily become hostile for ten minutes and have an increased speed boost. This affects all animals including tamed pets like parrots or wolves. Make sure to equip some armor because these beasts are powerful! Has a 33% chance to occur every hour. Can occur during a Blood Moon.

Blood Moon:
Mobs have an increased spawn rate and have a very high chance to spawn equipped with armor. Mobs can spawn with up to double the amount of health they normally have. For every monster spawned, there is a 25% chance that a Vex will end up spawning as well. Players to not regain their health unless it is from a golden apple or a regeneration potion. Has a 5% chance to occur every night.

I hope you guys are as excited as we are about these events!

All of the "never-seen before" features that you listed in the description have been seen before. In the vast field of Minecraft servers, these features don't bring anything new to the table. I was expecting the server, by its name, to have classic old mods or plugins. Retrocopy might be a more fitting name for your server.
