The first adventure
Sky Defender
Flight to the Floating Palace
Outfly a pursuing spike wall, blast through the original barrier course, gather gold and silver coins, and survive six increasingly demanding worlds.
Clear barriers
Use unlimited rapid fire to break through the 18 wall positions in each world. The original wall system rewards holding fire continuously on one spot.
Protect four lives
You begin with four lives. Collisions with barriers, enemies, and the pursuing spike wall cause damage, so use the protection orb when the route closes in.
Collect and score
Gold coins are worth 50 points, silver coins 25, enemies 100, spikes 75, and destroyed walls 300.
Reach the palace
Complete each of the six worlds by surviving the course and reaching the floating-island palace.
Controls
Fly your way.
Left-hand flight control
Use the left side of the screen to guide the helicopter.
Right-hand rapid fire

WASD / arrows + Space

The separate sequel
Sky Defender 2.0
Beyond the Floating Palace
Twelve worlds rebuild the flight with faster movement, live flaming defenses, searchlights, magnetic bombs, extra lives, distinct collectibles, and special underwater survival rules.
Choose your mission
Select any of the twelve levels before takeoff. Levels 1–6 are daytime flights; Levels 7–12 take place at night.
Navigate nine obstacles
Each level uses nine randomized obstacle positions with twice the original spacing: flaming walls and armed ground stations.
Fight the fire
Flaming walls cause damage only on direct contact. Fire anywhere on a wall for two cumulative seconds to destroy it.
Silence ground defenses
Searchlit anti-aircraft stations fire upward on standard levels. Special underwater Levels 3 and 9 replace them with missile silos that launch explosive torpedoes every second.
Watch your oxygen
Underwater missions begin with a bubble around the pilot’s head. Fly through a full-helicopter air pocket to reset the visible ten-second countdown. New air pockets rise every five seconds.
Use the arsenal
The protection orb lasts five seconds. Carry up to five fast magnetic bombs; each bomb seeks an armed station or silo and instantly destroys anything it touches.
Find an extra life
A photoreal golden peanut with wings appears every other level. Collecting it adds one life—even above the original four-life limit.
Fly beyond the palace
The floating palace island appears in the center near the finish. Fly completely past it to clear the level and trigger the celebration.
Controls
Three ways to defend.
WASD / arrow keys
Guide the helicopter with the keyboard or left-hand touch control.
Space
Hold Space or the rapid-fire button to shoot enemies and walls.
B
Press B or the bomb button to deploy one of five bombs.
