Description
Fusion started as a pack for me and my friends to play on our own server. It kept growing until it had pretty much everything we wanted, so here it is.
It's a kitchen sink pack for 1.20.1 Forge with around 460 mods. There's no tech tree you have to follow and no stages. You can start a Create factory on day one, go straight into Ars Nouveau, or head for the Twilight Forest. The mods are tied together with cross-mod recipes, so whatever you get into early still helps later.
### What's in it
Tech: Create (and about 50 addons), Mekanism, AE2 with MEGA Cells and Advanced AE, Immersive Engineering, Immersive Petroleum, PneumaticCraft, Industrial Foregoing, Integrated Dynamics, RFTools, Powah, Modular Routers, Mystical Agriculture and CC: Tweaked.
Magic: Ars Nouveau and 9 of its addons, Botania, Blood Magic, Iron's Spells 'n Spellbooks, Occultism, Malum, Forbidden & Arcanus, Mahou Tsukai and Embers.
Exploring: Ad Astra rockets and planets, the Twilight Forest, Blue Skies, the Undergarden, the Bumblezone, Alex's Caves, Ice and Fire dragons, Cataclysm bosses, YUNG's structures, When Dungeons Arise, Valkyrien Skies ships, Immersive Aircraft, and a flat mining dimension with Allthemodium.
### Old favorites
If you played the old Tekkit or Crazy Craft packs, a lot of it is here in updated form: BuildCraft, Railcraft, Project Red (basically RedPower), Ender IO, Thermal, Draconic Evolution, Big Reactors, Compact Machines and OpenBlocks elevators. On the Crazy Craft side there's the Big Bertha (you have to earn this one), Witchery style witchcraft with Enchanted, Vampirism and Werewolves, and morphing into mobs you've killed with ReMorphed and Woodwalkers.
### Quests
The quest book (press K) has 1,044 quests in 52 chapters. Think of it as a guide, not a gate. It walks you through each mod and hands out some useful supplies along the way. Quest items are never taken from you. Item rewards are shared by your team, and XP goes to whoever claims it.
The end goal is the Convergence Core, which needs stuff from the tech, magic and boss sides of the pack.
### Running it
Honestly, for a pack this size, I'm kind of surprised how well it runs. Over 460 mods and it stays stable through long sessions on our server. Give it 8 GB of RAM to start, or 10 GB once your base gets big, and keep render distance around 8 to 10. Performance mods are already set up (ModernFix, FerriteCore, Embeddium and others). Keybinds have been gone through so nothing overlaps out of the box.
Shaders are optional. Oculus is included, and BSL, Complementary Reimagined, Sildur's Vibrant, Solas, Bliss and MakeUp Ultra Fast are already in the shader menu.
### Servers
The "Fusion" entry in your server list is our own SMP. It's whitelisted, so it's not open to the public.
A server pack is attached to every release under Additional Files. Unzip it, run run.sh or run.bat, and it installs Forge and grabs the few mods that can only be downloaded from CurseForge directly.
### Mods not hosted on CurseForge
These two are on CurseForge's approved list:
- CC: Tweaked 1.120.2 by SquidDev (CCPL)
- Noisium 2.0.1 by Steveplays28 (LGPL-3.0)
### Credits
All the mods belong to their authors. Huge thanks to all of them. The quests, scripts, configs and menu are by me, Mjolnir Loki. The main menu background image was made with AI.
