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 Everything10 slots × 75 parts: motors, gears, treads, wheel hubs, guide rollers, chassis, batteries, shells, wings and roller staysEvery 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 weightPhysics You Can SeePractice telemetry: speed-vs-distance curves, per-corner minimum speeds, motor temperature and battery voltage, ghost comparisonThe 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 trackThe speed-vs-stability tension isn't hand-tuned numbers — it emerges from a 240 Hz physics simulationNine Rivals, Zero Rubber-Banding9 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 seasonWhen the speed demon overcooks a corner, he really does fly offSettle It in the PaddockLost, 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 backWin, 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 Bones8-round season, F1 scoring, lane picks in reverse championship order — backmarkers choose firstSponsor objectives, prize money, parts unlocking in waves — a proper arms raceTransfer offers, paddock drama events, post-race headlines: your season tells its own storyDeterministic SimulationFixed-step 240 Hz physics: same seed + same setup = identical result, frame for frameWhen you lose, it's not luck. Find the missing 0.3s in the telemetry, fix the setup, go again.Simplified Chinese / English.Redline Rookie is an independent game, not affiliated with, sponsored by, or endorsed by TAMIYA.
