Supply Lines... is an optional asset mission given by Zero at his RC Shop in Garcia, San Fierro. You control a remote-controlled RC Baron plane equipped with dual machine guns to eliminate Berkley's 5 delivery couriers across San Fierro and safely return to Zero's rooftop before running out of fuel.
Essential Fuel Management Rules
The RC Baron's fuel meter decays continuously whenever the engine is accelerating. To conserve fuel:
- Release the accelerator button (W or right trigger) when coasting downhill or making turns. Gliding uses zero fuel!
- Do not fly at maximum altitude unnecessarily; fly at low street levels.
- Land directly on top of van couriers before shooting to guarantee 100% bullet hit accuracy without wasting time.
Recommended Courier Elimination Order
- Target 1 (Van near RC Shop): Fly south immediately after launch to destroy the first delivery van on the road.
- Target 2 (San Fierro Docks Van): Head west towards the port docks to eliminate the second courier van.
- Target 3 (Motorcycle Courier): Head north into downtown San Fierro to shoot the courier riding a Sanchez motorcycle.
- Target 4 (Pizzaboy Scooter): Fly east to eliminate the courier on the Faggio/Pizzaboy scooter.
- Target 5 (Final Van): Finish off the last van driving near Queens/King's district.
