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

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.

12 November 2026Version 0.30.39
The man traveler's hood, lower and softly pointed
Before: the hooded warrior's head from the front and the left side, the hood a tall box standing well above his hair, with a point sticking out behind
After: the same two views, the hood lower and coming to a soft point over his hair, its brim back so his fringe and face stand just ahead of it
- The man traveler's hood sits lower and comes to a soft point, as on his character sheet, where it used to stand as a tall box over his head. Its brim is a little further back, so his face is nearer the opening, and the point behind his head is shorter.
- It's the same hood up close, at a distance, in any dye, and lowered onto his shoulders. His poncho hangs as before, and the woman traveler's cloak is untouched.
12 November 2026Version 0.30.38
The man traveler's skin, less orange
Before: the man traveler's face close up in the meadow, his skin a saturated orange-tan
After: the same face, the skin a paler, softer peach, the lips and brows as they were
- The man traveler's skin is a paler, softer peach, closer to his character sheet. His face, neck and hands change together, so they still match each other in sun and in shade.
- His features, hair and clothes are untouched, and so is the woman traveler.
12 November 2026Version 0.30.37
The poncho's hem is a worn, stitched edge
Before: the hooded warrior's poncho from the front, side and back, a thick wavy brown band running a little above its hem all the way round
After: the same poncho with a thin worn edge, a stitched line just inside it and a little dust scuffed along the hem
- The brown band that ran round the travelers' ponchos a little above the hem is gone. The hem is now a thin worn edge with a stitched line just inside it and dust scuffed along between the two, heaviest at the poncho's points, as on the Hooded Swordsman as drawn.
- A dyed poncho keeps the same thin worn edge in place of the old stripe.
