Fly & blast · Browser
Zenith
Test pilot VEGA, one rocket suit, no ceiling. Steer with a mouse or a thumb, lase what you can, thread what you can't — from the morning city past the Kármán line, as long as your cores hold.
How it plays
Point. Blast. Ascend.
Steer
VEGA shadows your cursor or thumb — glide left and right, bank into the turns.
Blast
Click or hold to fire twin lasers. Watch the heat gauge: spray too long and you vent.
Ascend
The sky never ends and never slows down. Three cores between you and gravity — altitude is the only score.
The climb
How far up is up?
Space starts at 100 km
Every marker is a real altitude VEGA crosses, and the line the game writes when you reach it. Keep scrolling and the sky does what it does in the run.

- ZENITH?not yet. higher.250,000 m
- DEEP FIELDnothing up here but you400,000 m
- Opposition
- Weather balloons and blimps give way to drones, storm walls, burning meteors, satellites and homing sentries. Past the mesosphere, alien interceptors hunt your column and shoot back — and every 60 km a gunship parks overhead and opens up.
- Scoring
- Altitude is the score, and every kill adds to it — from 120 m for a balloon to 3,200 m for a gunship. Shooting is climbing, which makes the heat gauge a decision instead of a nuisance.
- Power-ups
- AEGIS shield, laser overdrive, spare cores — knocked loose from whatever you destroy.
- Milestones
- Real atmosphere, called out as you cross it. At 100 km the game tells you what you already feel: you are officially in space.
- Session
- A run lasts as long as your reflexes. Minutes, usually. It remembers your zenith.
- Progress
- Best altitude saved on your device. No account, no sign-in.
- Plays on
- Any modern browser, desktop or phone. Mouse, trackpad or thumb.
- Weight
- A single file. Loads in a blink, plays offline.
Questions
Before you launch.
Do I need an account?
No. Nothing to create, nothing to remember. Your personal zenith lives on the device you fly on.
Does it work offline?
Yes. Once the page has loaded it runs without a connection, all the way to deep space.
How does it play on a phone?
Drag to steer, hold to fire — everything happens under one thumb. Same sky, same speed.
How high does it go?
There is no top. The Kármán line at 100 km is where space officially begins; your best run is your zenith, and there is always a higher one.
