Hello ufolev,
Thank you for your comments!
Yeah the 'Arms Expo' mission has the mission area quite far away from the start point. This was intentional, as most of the original missions are quite small and are at an unrealistic short range from the base. I also wanted to set the objective in this mission further away, so that the player could 'enjoy' the flight without having to worry about getting shot at... and when you get there, you are 'rewarded' with a display of nearly every enemy unit in the game (but - SPOILER ALERT - they don't fire at you)!
I still have some ideas for more missions, but I don't know when I'll get round to making those. I just wanted to make a bundle and get them out there as a contribution to the mission making community.
Any newcomers to mission making may find my new mission editor hints and tips page interesting or useful...
