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.
