Into The Grey

It's essentially a Spagetti Western with ATVs and motor bikes. Nothing grey about it.  The main character is introduced as operating in a grey area between the moral and something but she's clearly a goodie and the rich evil dude is clearly the baddie.

Like a Spagetti western there are lots of guns and galloping.  No suspense and no subtleties. Galloping steeds and all challenges are solved with things that go bang.

There are two or three recognisable characters on each side and then innumerable extras who seem to continually appear holding guns with infinite bullets. The goodies have those bullets that hit their mark and leave piles of bad dead. 

I pondered that its a very white cat the only goodie who died was also the only black guy on either side and being a goodie,  he sacrificed himself to trigger an explosion that killed dozens of baddies and gave the goodies time to escape..... until the next of the unlimited baddies appeared over the Ridge.
