Coast trainer
Sky Lark
SignatureStandard cannon
Steady and bright, and free from sector one. The craft you learn the coast on. Guns, bomb, and Overdrive all behave at their baseline.
Free browser campaign · 42 sectors
Fly a low-poly fighter over coasts, night water, storms, ice, volcano shelves, and a quiet space edge. Guns fire on their own. You fly the line.
01 — Story
Sky Strike 3D is a vertical-scrolling airplane shooter built for a browser tab. The fighter sits over water, islands, and later over weather that the coast never trained you for. Each sector is a short flight with a boss at the end. The campaign badge in the hangar is explicit: clear all 42 sectors, from the first bright coast to Edge Light.
You do not hunt a fire button. The cannon runs on its own. Your work is the path: stay low enough to see a shot coming, sweep for coins, and keep a bomb for the ring attack a boss likes to throw. Special starts Overdrive, then it has to cool. Wingman drones, up to three, fire with you once the hangar has them.
The opposition is named. Captain Voss opens Glasswater. Dreadnought Manta holds Kelp Break. Farther out you meet Siege Barge Kett, Carrier Nox, Leviathan Orr, Baroness Quill, and Admiral Harrow, then a second book of night, storm, arctic, volcano, and space-edge captains. They are targets with hull bars, not a story that asks you to hurt anyone on the ground.
Between sectors the hangar spends coins on cannon bore, feed motor, armor plate, and drones. Five extra planes wait on sector gates: Coast Comet, Night Finch, Ember Swift, Mint Halo, and Pebble Courier. Endless mode keeps going after you want a score instead of a map. Daily orders refresh on the calendar day and pay a small coin claim. Nothing in the hangar is a purchase.
Waves of fighters, elites, gunboats, and turrets scroll down the water. Density and aim tighten as the sector number climbs. A boss arrives on a timer with its own hull. Clear the sector without a hull hit and the Smooth landing badge can tick. Night, storm, arctic, volcano, and space-edge clears each have their own badge.
Coins are the only currency. They buy upgrades and planes. They are not tied to an account, a wallet, or a shop. If you leave and come back, the save is the browser you played in. A different device starts a fresh hangar.
Roster
Six craft live in the hangar. Sky Lark is yours from the first sector. The other five open as the campaign moves, and coins buy them.
Coast trainer
SignatureStandard cannon
Steady and bright, and free from sector one. The craft you learn the coast on. Guns, bomb, and Overdrive all behave at their baseline.
Racer
SignatureHarder cannon
A cream racer unlocked after sector 6 for 600 coins. Shots hit a little harder. The right pick when a barge soaks damage.
Violet flyer
SignatureFast Overdrive
Opens at sector 14 for 1,400 coins. Special cools down faster, so you can spend Overdrive on more than one wave.
Sprinter
SignatureExtra bomb
Opens at sector 22 for 2,600 coins. Starts a sector with an extra bomb charge. Useful when the ring attack fills the screen.
Pale scout
SignatureCooler Special
Opens at sector 30 for 3,200 coins. Special cools a little faster without giving up the extra bomb slot to something else.
Hauler
SignatureExtra bomb
The last hangar craft, sector 36 and 4,200 coins. A sturdy hauler that also starts with an extra bomb.
Kit
The guns never wait for a trigger. You spend attention on the line, the bomb, and Overdrive.
Gun upgrade
RoleDamage
Each hit lands harder. Bought with coins in the hangar between sectors. The cannon still fires on its own.
Gun upgrade
RoleRate
Shortens the gap between shots. Pair it with a harder bore when elites start soaking the stream.
Hull
RoleOne more point
Adds a hull point. You can see the pips under the bomb button. A clean sector still matters more than a thick hull.
Limited charge
RoleScreen clear
Clears enemy shots and cracks nearby hulls. Charges are limited. The flight card tells you to save one for the boss.
Special
RoleBurst, then cooldown
Space or the Special button. A short burst, then it cools. Night Finch and Mint Halo cool it faster. Rank on Spark can add a bomb at rank 3.
Escort
RoleShared fire
An escort that fires with you, up to three. Two drones earn Full wing. Three earn Flight of three.
Rides
You fly one craft. The rest of the sky is escorts, boats, and the barges that close a sector.
Yours
RoleOne of six
Speeder, racer, and heavy speeder bodies from the Kenney craft set, scaled and colored per plane. You only fly one at a time.
Escort
RoleAuto fire
Small escorts bought in the hangar. They follow and shoot. They are not a second life.
Opposition
RoleRed shots
The scrolling traffic. Elites take more hits. Their job is to push you off the coin line.
Surface
RoleTurrets
Boats on the water under the flight path. Turrets and larger hulls show up more often as the sector number climbs.
Boss hull
RolePattern fire
Dreadnoughts, carriers, kites, hives, glaciers, calderas, and the edge keepers. Each sector names the barge on the boss bar.
Ground
The campaign is forty-two named sectors. The first ten are bright coast. Later skies shift to night, storm, ice, fire, and the edge.
Sectors 1–10
KindIslands and open water
Glasswater through Final Vector. Left coast, both shores, or island chains. The training sky, and already a full set of captains.
Lantern skies
KindOwl and hive bosses
Lantern Bay, Velvet Reach, Starling Shelf, Quiet Current, Moonwell, and later Night Lattice. Clear one for the Night watch badge.
Squall skies
KindKites and dreadnoughts
Gale Pocket through Cloudbank, plus Gale Ribbon. Rain, whitecaps, and captains who like a moving lane.
Ice shelf
KindGlacier and aurora
Frostline, Pale Fjord, Aurora Run, Sealight, Ice Market, Snow Dock. The Ice run badge asks for one clean arctic clear.
Cinder water
KindCaldera barges
Cinder Shelf through Last Flare, and Ember Dock. Ember path is the badge.
Sectors 31–34 and 39–42
KindNova, prism, sentinel, wisp
Rimlight to Edge Light, with a few returns to older weather in between. Star run is a space-edge clear. Coast to edge is all 42.

Paint schemes beyond the six built-in palettes are not for sale. A cosmetic skin track is coming soon and will not cost money.
Hands

| Bomb, or B | Clear enemy shots and crack nearby hulls. Limited charges. |
| Special, or Space | Start Overdrive. It then cools down. |

Spec
Minimum
A current Chrome, Edge, Firefox, or Safari on a phone, tablet, or computer. WebGL enabled, about 2 GB of memory, and a keyboard, mouse, or touch screen.
Recommended
Desktop Chrome, a mouse, and a graphics chip that can hold a steady frame rate. Close other heavy tabs. Headphones make the missions easier to read. The coast is readable on a mid-range phone; a larger screen makes the later barges easier to read.
Questions
Yes. It is free in the browser with no download, no account, and nothing to buy. Coins are earned in play.
Forty-two. The hangar badge Coast to edge asks you to clear all of them, including the space-edge sectors that finish on Edge Light and Keeper Edge.
No. Continue after a hull break is optional, and the game does not require an ad to retry the sector.
In this browser. Best score, coins, planes, drones, and badges stay on the device. A new browser starts a new hangar.
It is aimed at everyone. Planes and boats are simple 3D shapes. There is no blood, no chat, and no purchase prompt.
So the skill is the line you fly. Bomb and Overdrive are the two choices you time yourself.
