Redline Rookie: A 4WD Racing Career

Once the light goes green, all you can do is watch (and put your car back on the track when it flies off). The race was already won — or lost — in your garage.

Redline Rookie is a career racing game about pre-race engineering — a love letter to the mini 4WD hobby. No throttle, no steering, no fake "boost button". Your only weapon is the setup you built before the start line.

Setup Is Everything

10 slots × 75 parts: motors, gears, treads, wheel hubs, guide rollers, chassis, batteries, shells, wings and roller stays

Every part maps to real physics — torque curves, drivetrain efficiency, rolling resistance, roller friction, center of gravity, voltage sag. No fake stat buffs.

The garage shows live derived stats and deltas: top speed, acceleration, per-corner stability margin, total weight

Physics You Can See

Practice telemetry: speed-vs-distance curves, per-corner minimum speeds, motor temperature and battery voltage, ghost comparison

The stability index S decides everything: under 0.85 you're solid, 0.85–1.0 is dancing on a knife edge, S≥1 means flying off the track

The speed-vs-stability tension isn't hand-tuned numbers — it emerges from a 240 Hz physics simulation

Nine Rivals, Zero Rubber-Banding

9 AI drivers with personalities: the reckless speed demon, the steady veteran, the gifted rookie, the rich kid with deep pockets…

They run your exact physics, shop in your exact store, and grow on real budgets across the season

When the speed demon overcooks a corner, he really does fly off

Settle It in the Paddock

Lost, and still mad about it? Call out the race winner in the paddock for a 25-second fistfight. Left click punches, right click guards, and a guard timed just before their punch lands is a parry.

The loser gets a part smashed off their car (two on a KO), pays for the repairs and waits a race to get it back

Win, and the champion starts the next round on the cheapest spare in the shop. Lose, and it's your car that gets smashed.

A Career With F1 Bones

8-round season, F1 scoring, lane picks in reverse championship order — backmarkers choose first

Sponsor objectives, prize money, parts unlocking in waves — a proper arms race

Transfer offers, paddock drama events, post-race headlines: your season tells its own story

Deterministic Simulation

Fixed-step 240 Hz physics: same seed + same setup = identical result, frame for frame

When you lose, it's not luck. Find the missing 0.3s in the telemetry, fix the setup, go again.
