Xuverse

Meet the Xu

Xu are the creatures of Xuverse. Yours fights beside you, helps with the skills it likes and picks up a personality from what you do together. There are thirty to befriend, in rare colours too, and about one in two hundred is gilded.

Seven regions

Each region has its own resources, Xu and weather. Travelling between them takes real time, and things can happen on the road.

Spots

Pull up a seat

Each skill has a place in every region, like the dock for fishing or the forge for smithing. When you work there, you sit next to whoever else is there and share a chat.

Realm boss

Mother Snowdrift

Every Saturday a realm boss wakes for two days. Every fight anyone wins counts toward the same total, and everyone who helped gets rewards by mail. The next one wakes Sat 17 Oct.

Festivals

Hallowed Nights

Festivals bring their own Xu, quests and rewards for a few weeks at a time. Hallowed Nights is on until Mon 2 Nov.

Primverse

A shared 3D world its people build

Every island starts bare: no houses, no trees, no rules about what goes there. Shape the land, build whatever you can picture, make it move and glow, then open it to everyone. The tools come with the world, so there is nothing to export and bring back.

Model anything

A whole 3D modeller inside the world: extrude, bevel, loop cut and knife, with materials and UVs.

door.lua
local open = false
local swing = euler_to_quat(
  vec3(0, 0, 90 * DEG_TO_RAD))
local closed_rot

function on_start()
  closed_rot = get_local_rot()
end

Make it do things

Scripts in Lua: doors that open for friends, vehicles, vendors, games that keep score. Every function has a wiki page with an example.

lava.lua
function surface(p)
  local flow = vec2(p.time * 0.05, p.time * 0.02)
  local heat = fbm(p.uv * 3 + flow, 4)
  local hot = smoothstep(0.45, 0.75, heat)
  return { color = mix(crust, glow, hot) }
end

Draw how it looks

Lava that flows, water that ripples, a hologram that flickers. Write a surface in a few lines, or snap it together from blocks.

Shape the land

Raise hills, dig out a bay and paint the ground. Lay a road where you click and the land is cut and filled to meet it.

Go and see what people made

Land on somebody’s island, follow the shore, or take off and look down on it all. Fly, sail and swim between islands, or teleport straight to a place on the map. Every place is rated General, Moderate or Adult, and you choose what you see.

An island of your own

Pick a kind of region, an island to start from and a spot on the map. Decide who may visit, build or stay, and sell what you make.

An Aeons planet in the stone age, with the names of its first peoples on the land

Aeons

A planet of tiny people that writes its own history

Each world is generated from a seed: land, climate, oceans and the tribes that wander onto them. They settle, found nations, trade and go to war, era by era from the stone age toward spaceflight. Nothing is scripted.

Watch from orbit at whatever speed you like, click anyone to see who they are, or step in as the god of the place.

Updates

Recent Xuverse updates

All patch notes are in the game

· Xuverse 1.2.24

Companions and rankings, brought into line

  • BetterCompanion profiles now keep their portrait anchored at a comfortable size while the full profile flows naturally down the page—without a cramped scrollbar inside the details card.
  • BetterCompanion care opens as a full-height drawer from the right on desktop, with a cleaner portrait backdrop and no hard line beneath the Xu. Phones keep the familiar bottom sheet.
  • FixedThe main leaderboard now ranks and displays Adventurer level instead of the sum of every skill. Its weekly view follows Adventurer XP, while individual skill boards remain unchanged.

· Xuverse 1.2.23

Cleaner care and sign-in screens

  • FixedThe companion care panel now fills the available height cleanly, shows the Xu roster without cutting a card in half, and no longer leaves a large empty gap above the Feed or Give action.
  • FixedCompanion profiles now keep the portrait and details in equal rounded cards. Long histories scroll inside the details card instead of stretching the artwork or the whole page.
  • BetterCompanion profiles now show exact XP progress and a live stat overview for health, MP, attack, dexterity, speed and care performance, with a direct path to training and talents.

and 1 more

· Xuverse 1.2.22

Friend actions that know who’s who

  • FixedRight-clicking an existing friend now shows Remove friend instead of Add friend, and asks for confirmation before removing them. Incoming and pending friend requests also show their real state.

The studio

About IdleFly Games

IdleFly Games is a small independent studio. We started on the web, so Xuverse, Primverse and Aeons all open in a browser with nothing to install, and their worlds keep going when you close the tab.

We also build our own tools, including a game engine of our own, and we plan to make games that run outside the browser too.

Xuverse is our main game and gets updates most weeks. It is free to play, with no ads and no energy timers. Plus, the optional membership, adds comfort and looks, never power.
