Stop and shoot at the truck with 3 cannons.
Yeah, that tip was really useful. The big truck ain't so tough. If you find the right spot (near the front) then you won't take any damage from it either.
@Hewskie - I read your post about the barrels and figures that the only way to do it was to "zone". When I got there I did a few donuts to keep the bad guys busy, and hoped for some of them to slide into the barrels. whether that worked or not, I kept an eye out for a gap or some blue barrels and made my runs appropriately. Seemed to work and I didn't die ... !
I just had a dream run - got thru the first two levels on one guy. But trashed the car near the end of lv2 and had to walk over the bridge!
I got 60100. I had never been to lv3 --BINGO! Either that, or I was attempting to say "before" but it was too many letters to type--, so I died pretty quick. Will try to post pics later.
