I enjoyed the game up to a certain point.
In the original campaign, at one point your squad member gets ambushed and kidnapped. You try to go save him and get kidnapped yourself. You have to watch a cut scene of your squadmember getting assassinated by the kidnapper, then get freed by your platoon later on while the kidnappers escape. Then you have to go hunt these guys down before they flee the country. Never could find them on a huge 100x100km map... You are supposed to talk to the locals and try to get there where abouts and trap them in before they can flee, but they always got away on me.
The mission was very boring to me, because you basically are just driving around the huge map trying to figure crap out, and if you don't do it in 2 hours or so (not game time, real life time), they get away... Then you have to revert, and start over...
Thats when I quit playing.
