Worldstart

Kauaʻi in the game: a hero in the long grass by the Start ring, a waterfall through it and jungle behind

Build islands. Race for treasure.

A fantasy island builder and team treasure race. Land with friends, fight monsters and rival teams with swords, bows and magic, and claim the gold. Then design a raid for your friends to try.

Race for the treasure

Land with your team, cross an island full of monsters and rival players, and claim the gold before anyone else does. That’s PvPvE: your team against both other teams and the world.

Claiming the treasure: a hero at the open chest of gold under a beam of light, a waterfall behind and the Lanternhorn closing in

A race across the island

Teams of four, 32 players a raid. The treasure sits by a boss at the island's heart: stand at it, alone and unhurt, and it's yours. Bots fill every empty spot, so a raid is always full, and another team is always on the ridge.

Fights with weight

Swords, bows and magic. Monsters telegraph, attacks commit, and a pack of Thornbacks will flatten a team that stands in the red. Grab a scroll from the grass for one huge spell, and save it for the boss, or for the team that got there first.

Meet your team in Start Plaza

Find your friends, pick a team and head out to a raid. Everyone looks different here: a pixel warrior, a low-poly archer and an anime mage on the same bench.

A farm to come home to

Grow, fish and sell to Pip between raids, and bring your team home after one.

Looks, not levels

No grinding for power. The gold you win buys new looks, never an edge, and every one works on every character.

Build the world

Design the next treasure race, test it with bots, and build the game alongside other players.

The raid island editor: flying over Kauaʻi with the treasure, the boss and monster packs marked as coloured beams

Build the islands

The current editor starts with Kauaʻi. From your farm, lay out the treasure, team landings, monsters and scrolls. Ask the builder for a change in plain words, or place it yourself. Press T to test the layout with bots. More island variety and wider building tools are in development.

The forge: Worldstart's code, issues and pull requests, with the builders who made it

Build the game, with your agent

Worldstart is built with its players. Connect your AI agent through the forge to propose new monsters, new looks and fixes as your character. Contributions go through review before release, and accepted work carries its builder's name.

Who you'll be

Human, elf, zombie, rabbit or dog, in whatever colors you like, drawn pixel, low-poly or anime.

Concept art by Mike. Every one of them is playable today; the game draws them its own way.

10 November 2026Version 0.30.1
Picking your hero
- On Select your character, each hero now holds their own class's weapon, and the hero standing in the meadow is always the card that's ringed, whether you arrow to it or point at it.
- Switching between heroes is instant: the travelers load behind the title screen, while it checks for updates.
10 November 2026Version 0.30.0
Travelers and dogs
The traveler, the woman, on the character screen
The man, in a red cloak
- Every hero is now a human or a dog. Every human is one of the two hooded travelers, a woman or a man: pick one under Body on the character screen. Your class shows in what you carry, and your cloak takes your color.
- Rabbits, wood elves, dark elves and zombies have left the islands, and everyone stands the same height now. If you played one, your hero is now a traveler with the same name, class, level, colors and looks.
- Humans keep Quick Hands and dogs keep Pack Instinct. Lucky, Green Mend, Unseen Blade and Won't Stay Down went with their races.
- Bots are travelers and dogs too, and they wear their team's color on their cloaks.
- The character screen is quieter: no Size or Appearance rows, no notes explaining the rules, and hats only for dogs for now (the hood doesn't take one yet).
10 November 2026Version 0.29.16
Smoother heroes
Before: an archer drawn in flat, faceted planes
After: the same archer shaded smooth
- We've turned off the faceted low-poly shading for now. Heroes, monsters and travelers' cloaks are now shaded smooth, catch a little shine in the sun, and their textures look clean instead of pixelated.
- Hats, weapons and shields use their more detailed models, so brims, blades and shields have rounder edges.
