SKY ACE
Take off, dodge the kamikaze divers and shoot down six giant bosses.
Your AP-2V Neptune rolls down the runway – or off a carrier deck – and climbs into a sky full of enemies. Formations of fighters sweep across the screen, bombers drop heavy fire and kamikaze divers lock on and dive straight at you: watch for the red warning line and slide out of the way. Hold the fire button (Space) to shoot – on a phone, keep your finger on the screen.
Shoot down a whole formation to win a POW box that powers up your guns, up to homing missiles. Pick up bombs to clear the sky, repairs for your armour and wingmen that fly beside you. Halfway through every stage the STORM RAIDER heavy bomber attacks, and at the end a giant boss with three phases waits – each phase angrier than the last. Six stages, free in your browser on computer or phone.
Two ways to fly: the classic top view, or press C (the VIEW button on a phone) for the cockpit view – sit in the pilot's seat behind the canopy frame and the reflector gunsight, with working speed, altitude, armour and power gauges and an artificial horizon that tilts as you bank. Enemies and bullets fly at you in 3D. Switch at any time.

Take off from the island air base. Fighter formations, the first kamikaze divers and gunboats on the sea. Boss: the six-engine GIANT BOMBER.
Stage 2: Island Chain
Launch from the carrier over a chain of jungle islands with anti-aircraft guns. Boss: a BATTLESHIP with ten turrets and exploding shells.

Rain, lightning and swarms of kamikaze divers. Boss: the FLYING FORTRESS – spirals of bullets and kamikaze escorts.
Stage 4: Carrier Fleet
Destroyers and gunboats fill the sea. Boss: an AIRCRAFT CARRIER that launches divers from its deck while its guns sweep the sky.
Stage 5: Volcano Isle
Lava coasts, tanks and gun nests. Boss: the LAVA FORTRESS with a giant twin cannon, bullet walls and spirals.
Stage 6: Sky Fortress
Above the clouds the enemy's flying fortress waits – seven turrets, missiles, rings and crossfire. Win to complete the mission.
Tips and tricks
- Keep moving in small steps – most bullets are aimed at where you are, not where you will be.
- When a kamikaze diver flashes its red line, move sideways, not backwards.
- Finish every formation: the last plane of a formation drops a POW or a medal.
- Save a bomb for a boss's final phase – it clears the screen and gives two safe seconds.
- Shoot the boss's turrets first (2,000 points each) – fewer turrets means fewer bullets.
- Hold Shift for slow, precise flying through dense bullet patterns.
Frequently asked questions
How do I fly from the cockpit?

Is SKY ACE free?
Yes. It is free to play in your browser with no download and no sign-up. The site is supported by ads shown below the game, never during play.
How do I play on my phone?
Drag anywhere on the screen to fly – the plane follows your finger. Your guns fire while your finger touches the screen, and the BOMB button is at the bottom right. It works in portrait mode too.
What happens when I lose all my armour?
You lose a life and come back with one gun level less. You start with three planes. Stages you have reached unlock on the title screen.
Who made the 3D aircraft?
Your plane is the AP-2V Neptune. The aircraft, carrier and air base are built from free models on CGTrader (royalty-free licence) and simple shapes made for the game. The game, sounds and code are original.
