How do I power up my guns in SKY ACE?

Shoot down a whole formation of enemy fighters – the last plane drops a red POW box. Each POW adds one gun level, up to level 5 with homing missiles.

How do I dodge the kamikaze divers?

A diver stops, flashes a red line towards you and then dives along that line. Move sideways out of the line – backing away down the screen does not help.

When should I use a bomb?

Keep at least one for the boss's final phase. A bomb removes every enemy bullet, damages everything on screen and makes you safe for two seconds.

SKY ACE Guide: Power-ups, Kamikaze Divers and Every Boss

SKY ACE is a free 3D vertical air combat shooter: take off from an air base or a carrier, fight through six stages and shoot down six giant bosses. This guide explains the power-ups, the kamikaze divers and how to beat every boss.

The basics

You fly the AP-2V Neptune. Hold Space (or Z) to fire and use the arrow keys or WASD to fly (hold Shift to fly slowly). On a phone, touch and drag – your guns fire while your finger is on the screen. You have three planes; each plane has an armour bar, so one bullet never ends the game.

Cockpit view

Press C (VIEW on a phone) to fly from the pilot's seat. Put enemies inside the yellow gunsight ring, watch the armour gauge and the artificial horizon, and press C again for the top view – the top view shows more of the screen when the bullets get thick.

Power-ups

Item	What it does
POW (red)	+1 gun level: twin → four guns → angled → wide spread → homing missiles
BOMB (blue)	+1 bomb (max 6)
+HP (green)	repairs 40% armour
WING (teal)	two wingmen for 20 seconds
SHLD (purple)	shield for 10 seconds
1UP (pink)	one more plane
RAPID (orange)	rapid fire, 15 seconds
2X (gold)	double score, 20 seconds
★ medal	500 points

POW boxes come from finished formations and from bombers, so shoot every plane of a formation, not just the closest one.

Kamikaze divers

Divers fly in, stop and aim – a red dashed line shows their path.
Slide sideways out of the line; they turn only a little once they dive.
Shooting a diver before it aims is worth 300 points and is the safest choice.

The STORM RAIDER mid-boss

Halfway through each stage the STORM RAIDER heavy bomber attacks with fans, homing missiles and crossfire. It flies away after about 30 seconds – shoot its six turrets first for 2,000 points each.

The six bosses

Every boss has three phases. Below two-thirds of its armour it fires two attacks at once and calls escorts; below one-third it fires three. Turrets on a boss can be destroyed one by one.

Giant Bomber (Coral Sea) – fans, bullet rain and rings. Stay below a wing, not under the nose.
Battleship (Island Chain) – exploding shells burst into rings: move away from a shell before it pops. Find the gap in the bullet wall.
Flying Fortress (Storm Front) – spirals and kamikaze escorts. Circle slowly with the spiral.
Aircraft Carrier (Carrier Fleet) – launches divers from its deck. Kill them early, then hit the deck.
Lava Fortress (Volcano Isle) – a twin cannon, crossfire and walls. Destroy the four corner turrets first.
Sky Fortress (final) – seven turrets and every attack in the game. Save bombs for its final phase.

Turrets are worth 2,000 each – more than most planes.
A POW at full power is worth 2,000 points.
