Expedition X
Expedition X, a NeoForge mod for 1.21.8, changes the usual order of progression in survival worlds through new dimensions, bosses and biomes.
What it does
Players who start an Expedition X world find that the usual order of progression is changed. Brand new dimensions, the Skylands and a set of extra biomes, structures, mobs, blocks and items sit between the start of a game and its end, and the author describes the game as beatable through this new path. Damage, hunger and bone loss add risk to exploration, and threats lurking in the dark punish players who travel without better gear.
The mod is built for players who want a harder, more polished version of vanilla survival, and for servers that run that version for groups. It is published for NeoForge only, on 1.21.8, and runs on client and server, so the server and every player need it. Expedition X is released under All rights reserved and is not open source.
Key features
Changed progression
New resources, challenges and adventures replace the standard path from the first tools to the final fight.
New dimensions and biomes
Additional dimensions, including the Skylands, and a set of new biomes and structures extend the world.
New bosses and loot
New bosses drop rewards, and a wider roster of enemies adds variety to exploration and combat.
Hard mode gear
Hard mode gating means diamond tools and armor are earned through the new path rather than found early.

Who it’s for: Players who already know vanilla survival and want a longer, harder route through new dimensions, bosses and biomes. Server owners running a group progression also fit the mod's scope.
