Welcome to HELL
You spawn in the world... everything looks normal, but it's not at all. At the latest at night you will realise that this modpack is literally hell.
The nights are pitch black, you want to build yourself up to escape the zombies? It's just stupid that they build themselves up after you.
You seek shelter in a village ? Well, creepers now have a nasty habit of blowing up houses and walls, so if there are no creepers around, watch out for what some zombies are holding! Is it maybe TNT?
This modpack gives everything to piss you off and make you desperate!
Did I mention the blood moons ? Or the tornadoes ? I think so, if not I have it now.
The goal is to survive as long as possible in hardcore mode. Hardcore is not for you? Never mind... you'll die a lot anyway :)
Recommendation: You can of course use Optifine with this mod, so that the fake light appears around you. But it is better NOT to use any shaderpacks because those only light the sky (this has been the case for every shaderpack tested so far). When the sky is lit up and and you can still see something without fakelight it is no fun at all. Do not forget to set the difficulty to Hard and maybe even turn on Hardcore mode too. No risk, no fun.
4 GB RAM is definitely the minimum requirement, although slight lags may occur.
Have fun playing. Enjoy!
