Island Challenge: unlock, swim ring and every boss
- Checked
- Game version
- Update 2.3.30
The Island Challenge is a game cartridge added on June 24, 2026. Xiaoming’s quests Development Documents (level 15: carry documents from the Farm Town School Library to the Arcade Hall) and A Token of Gratitude (hand in a Cardboard Box) give you the cartridge and unlock buying more. You start with nothing: none of your weapons or items come with you.
Rules on the island
- Swimming: you can swim across water to make new routes, but only with a swim ring (the Life Ring); without one survival is much harder.
- Supplies: buy from island vending machines and the Mysterious Merchant. Update 2.3.20 added Surgical Kits and Bone Splints to both and made portable vending machines open in 0.5 seconds; update 2.3.18 lowered arrow prices.
- Loot: containers dropped by enemies open without an inspection delay (2.3.20).
- Difficulty: since update 2.3.18 the island follows your selected difficulty instead of always using Balanced.
- Storm Robot: you cannot be hurt while inside it, and its damage was raised in 2.3.20.
Bosses and quests
Each “Island Challenge:” quest from Xiaoming asks for one boss and unlocks a cosmetic or blueprint.
