/01   THE LOOP

BRIDGES DIVIDE
THE RUN.

Every bridge you clear is a checkpoint — and a threshold. Cross it and the river answers back: the scroll speeds up, the enemies get meaner, and the weather turns on you. How far you push is your call.

/02   FEATURES

SIX THINGS WORTH
YOUR BATTERY LIFE

ONE-THUMB CONTROL

Tilt or drag — pick your poison. Steer, dodge and fire the whole run with a single thumb.

23 MACHINES

Jets, choppers, drones, heavy bombers and now a Star-Wars ion-fighter — each with its own HP, fire pattern and handling.

WEATHER THAT BITES

Storms aren't cosmetic. Rain, snow and fog change how you fly — and pay more if you brave them.

ANALYTIC COLLISION

Precise per-pixel hit detection reads the exact edge of every bank, so near-misses stay fair.

ESCORT DROP

Call in a wingman formation mid-run for extra firepower when a sector gets thick.

GAME CENTER

Global leaderboards and achievements. Beat your best, then beat everyone else's.

/03   THREE THEATERS

CALM RIVER. WILD CANYON.
THEN ORBIT.

NEON RIVER

✓ DEFAULT

The classic cyberpunk canyon. Wide cyan banks, magenta bridges, the occasional island. Where every pilot learns to fly low.

GRAND CANYON

◎ +35% COINS

Narrow water, orange cliffs, yellow bridges and dam gates. Tighter margins, cliff missiles, and a bigger payout for surviving.

STAR RUN

★ NEW · +100% COINS · 100K UNLOCK

Leave the atmosphere. Trench walls, dense turret gauntlets, probe-droid swarms and diving strikers. Double coins for anyone who lives through it.

In-game map selection with Neon River, Grand Canyon and Star Run

/05   THE SKY FIGHTS BACK

THREE WEATHER SYSTEMS.
ALL BAD NEWS.

ACID RAIN

Slick air, sluggish steering, and lightning strikes that light up the whole river.

ION SNOW

Sideways drift pushes you off your line. Commit early or kiss the bank.

SMOG BANK

The horizon vanishes. You'll spot the bridge only when it's almost on top of you.

Mission briefing showing four weather conditions

FLY LOW.
FIRE STRAIGHT.

Beat your best. Beat the world.
