Redline Rookie: A 4WD Racing Career

Once the light goes green, all you can do is watch. The race was already won — or lost — in your garage.

Redline Rookie is a top-down 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
7 slots × 55 parts: motors, gears, tires, guide rollers, chassis, batteries, shells and wings

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
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.
