Take to the skies in your fighter jet and shoot down six waves of enemy jets over a tropical ocean. Stay above the water, keep moving and fly through the glowing green rings to repair your jet and refill boost.
On a computer: W and S climb and dive, A and D turn, hold the left mouse button or space to fire and hold Shift to boost.
On a phone: drag the left thumb to steer (up climbs, down dives), hold FIRE and tap BOOST for a speed burst.
Your guns lock on to enemies near the centre of your view, so line them up and fire. Red tracer shots from enemy jets can be dodged by turning.
