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 ninja, a low-poly ranger 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.

6 November 2026Version 0.24.24
Light the way
The cave with the torch off
The same corridor lit by a torch
A White Mage barrier protects both practice heroes
Choose Hold or Tap to toggle sprint in Settings
- Explore a dark, winding cave from Offline playtest labs. Bring a torch or cast Lumos to see your way past the monsters. The cave is an early offline experiment with placeholder scenery, separate settings and no character progress or rewards.
- Choose Hold or Toggle sprint in Settings. Keyboard and controller bindings work across the island, hunts, offline labs and compatible raids. Stopping or opening a menu clears a toggled sprint.
- Practice healing, reviving and protecting yourself and an ally in the White Mage lab. Try stone, lava and lightning staffs, each with a different range, pace and effect. Spell values are provisional; the lab does not change live raid combat or your character's equipment.
5 November 2026Version 0.24.23
Roll a new island
A new island from above in the raid island editor, its race laid out
Its treasure on a hilltop clearing
- In the raid island editor, press G for a whole new island: a volcano, two peaks, a long ridge or a crescent round a bay (Shift+G for the next shape), each with its own valleys, beaches and sea cliffs. It comes with a race already laid out on it (landings, monsters on the way, scrolls and the treasure), ready to test raid. Ctrl+Z brings back the island you had.
- Ask the builder (~) for a new island too: "a long rugged ridge, not too tall".
5 November 2026Version 0.24.22
One "Time's up"
Before: "Time's up" at the top and on the race card
After: just the card
- When a race ends, the line at the top of the screen steps aside for the race card, so it no longer says "Time's up" (or who has the treasure) twice.
