About this Modpack

The sequel, coming to a server near you...
This modpack was originally made for the 20 Seconds to Midnight server, which is no longer up.
I've started work on 20StM's successor, Vertigo 4.1. No specific ETA on when it'll be out, other than "a couple months", but I'll be sure to link it here when it's getting close to being ready.
It's successor can be found on our Discord
About this modpack
20 Seconds to Midnight is a Steampunk-Fantasy modpack about trying to stop t͟h͟e͟ ͟e͟n͟d͟ ͟o͟f͟ ͟t͟h͟e͟ ͟w͟o͟r͟l͟d͟. You're dropped into the world of Sanctuary, a living world that you and 15 other people must build up in order to save it.
The Horde

An ancient relentless evil is lurking in the deep dark. It doesn't just feed, it hungers. And it's hunting you.
As you fight the Horde, it learns. It will start adapting to your tactics, mobs will fight better, harder, faster, and stronger and will make its' mission to make your life a living hell.
It's smart. You can't run from it, you can't hide. It will find you, and it will make you one with it. And it will not stop until the entire world becomes the Horde. Not unless you stop it first!
