About this game
Néon Starship is a horizontally scrolling shoot ’em up whose campaign takes place inside a giant creature. You fly a cyan fighter; your cannon fires forward by itself and you move in all four directions. You cross four organs in order: the throat, the lungs, the acid stomach and then the heart. Each has its palette, its enemies, its trap that is always announced before it hurts (walls that squeeze, a gust that pushes you, drops of acid, arteries swelling with the heartbeat) and its boss: the Larynx, the Alveolar Mother, the Pylorus and the Ventricle. Bosses fire curtains of shots: a single corridor stays open, and it lights up green a moment before. Enemies are told apart by shape: the charging fighter, the zigzagging weaver, the armoured tank that fires back, the cluster of five drones, and indestructible metal grafts to steer around. Four weapons are picked up in capsules, each on three levels: the spread shot, the piercing laser, the homing missiles and the shockwave. Picking up the same weapon raises it; a different weapon replaces it while keeping your level minus one; a hit costs one weapon level, never two, but never the weapon itself; the capsules of the weapon you carry drop more often. On top of that come a shield, two support drones, a bomb (B key or BOMB button) that wipes enemy shots and hits the whole screen, and extra lives. The charged beam, which you release with a press when its gauge is full, and the Force module, a pod that absorbs shots in front of or behind you, complete the arsenal. No hiding place holds: stay more than 5 seconds in the same spot and the creature spots you (“SPOTTED! MOVE!”) and every enemy aims at you, faster and faster. Defeating the Ventricle defeats the creature and scores 190,000 points; a tougher creature then opens, with tougher enemies, tougher bosses and points multiplied by its rank, up to rank 6. The score is the total of points, with no hidden combo. On a computer, the arrow keys or WASD fly, Space releases the beam, Shift or F switches the Force and B drops a bomb; on mobile you slide a thumb anywhere on the screen: the fighter follows your gesture without ever passing under your finger, and you tap BEAM, FORCE or BOMB. Néon Starship is free to play in your browser, with nothing to install. Create an account to sync your records, appear on the leaderboard and unlock trophies, from “First Assault” to “The Million”.

How to play
Cross a giant creature organ by organ, from the throat to the lungs, the stomach and the heart: bring down the boss of each organ, dodge its traps, and defeat the creature to face the next one, tougher.
Game rules
- You fly a fighter inside a creature. The scenery scrolls to the left, your cannon fires forward by itself, and you move in all four directions to dodge and line up. The campaign has four organs in order: the throat, the lungs, the acid stomach and the heart.
- Each organ has its own enemy mix, enemies a little tougher than in the one before, a trap and a boss: the Larynx (throat, 150 hit points), the Alveolar Mother (lungs, 190), the Pylorus (stomach, 230) and the Ventricle (heart, 230). Beating a boss scores points and opens the next organ, after a curtain of flesh.
- The enemies: the fighter charges straight (1 hit point, 100 points), the weaver zigzags in a sine wave (2 hit points, 150 points), the slow armoured tank fires back (6 hit points, 300 points), the drone arrives in a cluster of five (1 hit point, 80 points each). Indestructible metal grafts scroll past as well: you steer around them.
- Each organ has a trap that is always announced before it hurts: in the throat, contractions squeeze the walls (up to 190 pixels, with a 1.9-second warning); in the lungs, a gust pushes you to one side without hurting you; in the stomach, drops of acid fall from the ceiling then leave puddles; in the heart, scrolling arteries swell suddenly with the heartbeat.
- Four weapons are picked up in capsules, each on three levels: the spread shot (a fan of 3, 5 then 7 shots), the piercing laser (1, 2 then 3 lines going through 3, 4 then 5 enemies), the homing missiles (1, 2 then 4 missiles) and the shockwave (goes through everything, taller at each level, and wipes out enemy shots at level 3). Picking up the same weapon raises its level; a different weapon replaces it while keeping your level minus one (never below 1). When you carry a weapon, its capsules drop much more often than the other three.
- Capsules come from carrier enemies: at least one group in eight has one. They also give a shield (it absorbs one hit), a support drone (two at most), a bomb (three at most) or, once the first organ is cleared, an extra life (five at most). A capsule that no longer changes anything still scores 100 points.
- When you are hit, you lose your shield, your drones and one weapon level all at once, one per hit, never two. Your weapon is never lost: at level 1 it stays at level 1. Whatever took the hit (the shield or the weapon level) spares you a life; with no shield and a level-1 weapon (or no weapon), you lose a life. Your weapon carries over from one organ to the next, after a boss, after a defeated creature and even after losing a life. You start with 3 lives and 1 bomb; a hit leaves you 1.5 seconds of invulnerability.
- The bomb (B key, BOMB button on touch) wipes every enemy shot, deals 7 damage to every enemy on screen and 26 to the boss, and makes you invulnerable for 1.2 seconds. The beam charges in about 7 seconds; it never goes off on its own: the gauge stays ready until you release it with a single press.
- The Force module, a pod attached to your fighter, goes in front of or behind you: on its side it absorbs enemy shots and fires in support. It does not block obstacles or bosses.
- Anti-camping: if you stay more than 5 seconds inside a 90-pixel radius, the creature spots you (“SPOTTED! MOVE!”) and every enemy except the tanks aims at you, faster and faster. A boss fight that lasts over 40 seconds goes into a frenzy. No hiding place holds: you have to keep moving.
- Killing the Ventricle defeats the creature: 190,000 points, chain explosions, then a tougher creature opens and you gain a life. Enemies have 30% more hit points per creature, bosses 35%, traps are 20% more intense, enemy fire is more frequent, and all points are multiplied by the creature’s rank, up to rank 6; the difficulty climbs with every creature, faster up to the sixth and more gently after. Bosses also release curtains of shots across the full height of the screen, with a single open corridor: it lights up green a little over a second before, go through it. Five names follow one another: the Leviathan, the Kraken, the Hydra, the Behemoth and the Chimera.

How a run ends
The run ends when you lose your last life. There is no final ending: defeating the Ventricle moves you on to a tougher creature, and the campaign starts again at the first organ. Your score is the total of points: enemies, capsules, bosses, organ bonuses (1,000, 2,000, 3,000 then 4,000) and 190,000 points for every creature defeated, all multiplied by the creature’s rank.
Tips & strategy
Never stay still
After 5 seconds in the same place, the creature spots you and every enemy aims at you. Move, even a little: hiding does not work, neither in a corner nor behind the Force. Go through the free corridor that traps and boss curtains leave.
Stay loyal to your weapon
A hit takes your shield, your drones and one weapon level, never the weapon itself. Stick with the same weapon: its capsules drop more often, whereas switching costs a level. And grab a shield as soon as you see one, it spares a life.
Keep the bomb for the boss or for panic
The bomb deals 26 damage to the boss and clears the screen, but you can only hold three at most. It matters most when a whole volley closes in on you, or to finish a boss.
Read the warning before the trap
Contractions, gusts, drops and arteries are all preceded by a visible warning. The walls never close evenly: the warning shows the deeper side, so go that way.
Did you know?
The horizontally scrolling shoot ’em up took hold in arcades in the mid-1980s. That is where the charged shot appeared: hold the button to build energy, then release a ray able to skewer several enemies at once, an idea Néon Starship’s beam picks up.
The genre also popularised “organic” levels, where you cross the inside of a creature: fleshy walls, pulsing enemies, bosses that are organs. Néon Starship builds its whole campaign on it, with four organs and one boss per organ.
Frequently asked questions
- Is Néon Starship free to play?
- Yes. Néon Starship is completely free and runs straight in your browser — no download, no install, no paywall.
- How do you play Néon Starship?
- Hit “Play” to start Néon Starship. It runs on keyboard on desktop and on touch controls on phones and tablets — no controller needed.
- Do I need an account to play?
- No — you can play right away as a guest, and your best score is kept on this device. A free account (by email link, no password) syncs your high scores, puts you on the leaderboards and unlocks trophies.
- Does Néon Starship work on mobile?
- Yes. The game is responsive and fully playable with your fingers on phones and tablets, just like on desktop, with no app to install.
- Do I have to keep pressing to shoot?
- No, your cannon fires forward automatically: you never have to hammer a button for basic fire. Your attention goes to moving, to weapon capsules, to the beam and to the bomb, which you trigger at a moment of your choosing.
- What happens when I defeat the Ventricle?
- The creature is defeated: 190,000 bonus points, an extra life (five at most), then a tougher creature opens, with the scenery tinted in another palette. Enemies have more hit points, bosses even more, traps are more intense, and points are multiplied by the creature’s rank.
- Why does a “SPOTTED! MOVE!” message appear?
- Because you stayed more than 5 seconds roughly in the same place (within a 90-pixel radius). The creature’s defences then all aim at you, except the tanks, faster and faster. Moving is enough to make it stop.
- Which weapon should I pick?
- None is better everywhere: the spread shot covers the screen, the laser pierces rows, the missiles seek their targets and the shockwave goes through everything and, at level 3, wipes out enemy shots. You can only carry one at a time: another capsule replaces the weapon while keeping your level minus one (never below 1), whereas the capsules of the weapon you carry drop more often.
