This is simple demonstration on how to get the Heat Seeking Rocket Launcher at the very beginning of the game... from three different locations (it's not available anywhere else):
1) Whitewood Estates, Las Venturas 2) Tierra Robada, The Desert 3) Easter Bay Airport, San Fierro
Here's the map that shows the zones where you can trigger a 4-Star Wanted Level... notice that Bayside Marina is not included in any zone. http://www.isarapix.com/pix61/1200077... (thanks to P.D.Escobar for the map)
There's also a thin path where you can fly from Bayside Marina back to Red County, and not get a Wanted Level... that's what I did in this video.
NO CHEATS and no mods were used. This is a completely legitimate game. PC Version 1.0
