Three stacked layers: sky scaffolding, surface ruins, and the caverns below. Swing between them with your grapple and outlast the storm, which closes in from the sides, rises from the deep and drops from the sky. Gamepad supported.
Be the last player left. That's the whole game.
The color tells you how good the loot is. Deeper places have better chests. A chest can be one step better or worse than its color.
A brighter gun color hits harder and reloads faster. A hit to the head does extra damage.
Parachute glides down from the sky. A drill pod digs straight to the spot you picked. A gamepad works too.
