UltraMobCore

Night has fallen, mobs come out. But from now on, night will be 4 times longer than normal. Daytime is still as long as normal, so it's valuable time, whenever the sun shines.

If you're a true survivor, it'll be easy. But if you can't get shelter before nightfall, you'll have to survive 40 minutes of non-stop nighttime (and mob attacks). It sounds easy, i know...

NaturalRegeneration = OFF
KeepInventory = OFF
Best to play with 2-4 players, but badasses can try it solo.

Rules!
1. Do not touch the spawn/redstone box, this keeps it all working.
2. Do not cheat or hack in any way.
3. If you record, give me credit!
4. Have fun!

Challenges:
-Make a base, with everything to survive inside
-Make a full beacon
-Don't use ANY maps
