I was wondering how you get to 6 wanted level stars. I'm up to four but..

Either add this cheat:
R1, R1, O, R2, LEFT RIGHT LEFT RIGHT LEFT RIGHT
or get a tank (either from fort Baxter or spawn one) and just keep killing cops or blow up cars, thats how I do it.

It depends how much percentage you've done you can only get six stars at about 40% of the game finished.

You can get more than 4 stars by blowing up the helicopters with the rocket launcher that is found near the sunshine autos. You turn on the 2nd left and when you get to the building with a pool you will find it in the pool.

When you get 4 stars the FBI agents come in black cars and start shooting out of the roof at you. When you get 5 stars the SWAT team come with tanks and huge trucks. When u get 6 stars agents come down ropes from helicopters and start shooting ar you.

I hope this has helped you.

You have to do a certain amount of percentage and then you can get 5 and 6 stars.

Well there's actually two ways you can do this. You can either spawn a Rhino Tank,or you can always just raise you wanted level using the appropriate cheats, available at, well, this site.
