It would be nice if there were some missions where you don't go around and blow everything up. In the Corp, most missions I went on were Recon (hence the name). Most of the time, it was just intel gathering. I guess you need some shooting to keep it intresting. Maybe some good infiltration missions when you have to get in unnoticed and plant bugs. Maybe a SERE mission, or Search and Rescue, where you have to find a downed pilot. If you need information on units or tactics involved, I could help. I'm just not to good at making good missions that run well.
Or you could base it on a Operation that actually happened, like Operation Urgent Fury. I think those missions are the most intresting.
P.S. Is there a way to plant a type of bug, and use a command to simulate a camera?
