Gameplay, Controls, Interface Each of the six campaigns contains about eight or so missions. Upon completing the first mission, you might see one or two more appear from which to select. Complete one of those and a few more appear. I like this nonlinear approach. Typical missions put the Delta Force squad capturing an enemy base or infiltrating a camp.
Some missions are quite unique though.
My favorite was rescuing two downed chopper pilots who must survive in order to complete the mission. The convoy escort mission had great potential but tended to bog with all the activity. There is quite a rewarding feeling after completing a mission. However, I really found myself wanting to command the other members of my squad to pass off some of the heavy lifting. In the distance you might see the ubiquitous flock of birds which seem to be in all games now regardless of the genre.
