Hi there,
If u really want to add to ur mission and help build thes story to it i would learn about camera.sqs, is very simple to get the hang of.
I would try and avoid trigger cutscenes, not saying theres anything hugely wrong them, well except that there crap so go and find a camera.sqs tutorial.
Once you know how to use camera.sqs, you'll be able to make woteva u want. Choose wot angles u want etc etc.
Good Luck,
Cheers
