⚔️ World at War

Revamped AI gives mobs new brains and brutal tactics. Expect gear-wielding enemies, terrifying new boss mechanics, and mutant creatures. Beware the sculk sickness, it's a plague! Finally arm yourself and your base with turrets, or install surveillance systems using security craft, or even make a missle silo to launch missiles to your friends or foes! At day 4, mobs will begin to spawn with guns more commonly. At day 30, a random faction of mobs will raid your village or home with guns!

🌍 A Reimagined World

Explore an ecosystem reshaped by William Wyther's Expanded Ecosphere. Discover unique biomes, ancient structures, and scattered remnants of forgotten wars. Travel in style using modded vehicles, boats, and more. A great modpack for those who love to have a cute time while also venturing and being able to wield powerful weapons (a modpack for him & her).

Recommended RAM: Allocate 8–12 GB of RAM for smooth performance (Max amount recommended is 32 GB). Minimum RAM: 8 GB is playable, but not ideal for larger worlds or longer play sessions. It is also recommended if you are on a lower-end system, to turn off shaders. You "don't"need to, but if you feel the need to change some graphical settings for performance, keep in mind that when you change your leaves to "Fast", they may seem "glitched" because of a leaves resource pack that is loaded ("Fast" isn't necessary because of the resource pack). Use the following JVM Arguments for improved balance of FPS, load times, and garbage collection: (It's also recommended to change your keybinds as you load so you get a feel of all the features, this modpack includes lots of mods and certain keys can overlap, it is generally recommended to view your "R" keybind as this is used to reload and also to reload shaders.)
