Wash ashore with nothing. Punch trees, hunt raptors, grab glowing $AMBER — the only currency on the island. You carry it on your body. Everyone can see how much. Get it to an obelisk before someone takes it.
Hits chip shards off what you carry. Die and 30% shatters forever — the rest spills for anyone to grab.
Bank it at one of five obelisks and your survivor is gone. Back to Lv1. Higher level and hotter obelisks pay a bigger bonus.
Claim land far from the obelisks, then build walls, turrets and vaults around your flag. Turrets overheat. Extract and your base goes feral.
Fixed supply. Fees, shattered amber, bombs, armor, turrets, vault rot and rotting loot all flow back into the world pool.
