🌅 Build, explore, and reach beyond the sky.
Horizons Unbound is a Forge 1.20.1 sandbox modpack with more than 250 hand-picked mods. It brings together three things that rarely fit into one pack: big tech, deep exploration and a cozy, living world.
There are no quests, no gated progression and no forced path. One player might automate a whole valley with Create trains and Mekanism factories. Another might spend weeks digging into the strange biomes of Alex's Caves, sailing to the Twilight Forest or building a rocket to the Moon. A third might run a farm with seasons, cook with Farmer's Delight and furnish a cottage by the river. Every path is a good one.
The pack has been tested, cleaned up and tuned: mods that caused conflicts or did nothing were removed, broken recipes were fixed, chat spam on join was silenced and the configs were tuned for performance. It also comes with its own custom main menu.
✨ Highlights
- Tech: Create, Mekanism, Applied Energistics 2, Thermal, Immersive Engineering, Ender IO, PneumaticCraft, Draconic Evolution and more, all in one world
- Space travel: build rockets with Ad Astra and visit the Moon, Mars, Venus, Mercury and beyond
- A reworked world: Terralith, Biomes O' Plenty and Climate Rivers reshape the overworld, and Alex's Caves adds whole new underground biomes
- Hundreds of structures: YUNG's overhauls, ChoiceTheorem's villages, Repurposed Structures, Dungeon Crawl and more, with per-player loot through Lootr
- A world that feels alive: new animals, mob variants, seasons, ambient sounds, realistic reverb, falling leaves and dynamic lights
- Performance first: Embeddium, ModernFix, FerriteCore, ImmediatelyFast, Entity Culling and tuned configs
- Custom main menu and styled buttons throughout the game, made for this pack

🚀 Performance
A big pack doesn't have to run badly. Horizons Unbound ships with Embeddium, ModernFix, FerriteCore, ImmediatelyFast, Entity Culling, Starlight, Dynamic FPS, Clumps and the Fast Suite mods.
On top of that, the configs are tuned. On your first launch, Default Options sets sensible video settings: render distance 10, simulation distance 8, VSync off and automatic GUI scale. Updates never overwrite your own settings later.
🧑🚀 Getting Started
- Press J to open your map. JourneyMap also tracks your death points.
- Hover over any item and press R to see its recipe or U to see its uses in EMI.
- Hold W while hovering over a Create item to watch an animated Ponder tutorial.
- Many mods come with an in-game guide book. AE2, Botania, Immersive Engineering and PneumaticCraft are good places to start.
- Craft a Sophisticated Backpack early, because you will collect a lot.
- Press V to open the voice chat settings when playing on a server.
💻 Requirements
| Minecraft | 1.20.1 |
| Mod loader | Forge 47.4.10 |
| RAM | 8 GB allocated recommended (6 GB minimum, more than 10 GB is not needed) |
| Java | 17 (included with the CurseForge app) |
🌄 Shaders (optional)
Shaders are supported through Oculus, and Colorwheel makes them work with Create's contraptions. No shader pack is included. Drop any Iris-compatible shader pack, such as Complementary Reimagined or BSL, into your shaderpacks folder and enable it under Video Settings → Shader Packs.
❓ FAQ
Is there a server pack?
Not yet. A server pack is planned for a future update.
Can I add or remove mods?
Of course, it's your game. Please test with an unmodified install before reporting bugs, though.
Can I use another launcher (Prism, ATLauncher, …)?
Yes. A few mod authors don't allow third-party downloads, so your launcher may ask you to download those mods by hand.
The game crashed. What now?
Crash Assistant is included. It opens automatically after a crash and uploads your logs with one click. Please include that link when you report the issue.
My FPS is low.
Lower your render distance first. It makes the biggest difference by far. Also make sure that no more than 8–10 GB of RAM is allocated, and close other programs while playing.
