It's a Nuclear Pack (Roll Credits!)
It is optional but recommended that you will have to get Optifine 1.12.2 HD U G5, The pack struggles without it at 10gb of mem
This is a mid- to small-sized modpack based on NuclearCraft Overhauled, but to make the early game a bit easier, I threw in some Mekinisum and Thermal series.
Spicing up the world with some, you guessed it! World Gen. With Biomes O Plenty and YUNG'S better caves and minshafts, Dynamic Trees and spiceing up your food too, with Pams harvest craft and Nutrition that you need to manage, and don't forget the ever-changing time of year with Serene Seasons, and no good modpack would work without Wawla and other QoL things like mouse/inventory tweaks and some of the FTB mods.
With amour and weapon customization from Tinkers Constructs and Constructs Armory, Spartan Weapons, and more equipment from Travelers Backpacks and Baubles, or even cause disaster on a Nuclear Scale with Trinity!
Gotta make things look pretty, though, you can with the Macaws series of mods, Biblio Craft, and Sildur's Vibrant Shaders/Optifine? Oh, and did I tell you about the Sound? I didn't? Well, with the Dynamic sound and light mods, you can be scared out of your wits in the caves, while your running sounds good, and the light will keep up with you while you run.
But don't forget about the bread and butter of the pack, no, I am not talking about Pam's Harvest Craft. I am talking about Nuclear Craft Overhauled with MSRs and SFRs, and so many things that could go wrong. Good Luck!
TheCaptainsTV heavily inspires this Pack on YT, and this is my very first modpack I have made, so thank you for playing it, and I look forward to making more in the future.
