How do I unlock the ancient gates?

You can unlock gates by finding brass keys scattered around the island or by activating the required number of ancient floor switches to open the path.

What happens when the island risk level increases?

As risk increases from time and collected loot, the storm intensifies, more spike traps appear, and tougher enemies like guards and elite hunters will spawn to chase you.

What do the different chest colors and glows mean?

Chest glow indicates rarity, ranging from common to mythic. Higher rarities like legendary and mythic reward you with significantly more coins, but they can be harder to find.
