Ok.
I am making an mission where you are alone in woods. You have to go into a city nearby, and wait some time
(problem1:i want an radiomessage just like these"cease fire", but i don't know how to do that).
After that player waits 2-3 minutes and then a chopper comes. When it's above you it will crash down
(trigger: helo1 setfuel 0).
Then comes another message, where they say that some SLA units are closing to you. There's some other SF units outside the city, and you must join and lead em'. I did it like this: I maked the trigger and the join and lead waypoint and then synchronized them, but when i come to the city, i must go to the group and thats all i have done yet. After that the group should head to US base near and they would meet some SLA forces.
