Deep maps with plenty of tasks, challanging gameplay, good control over squad, and decent graphics and sound.
Squad control warfare games are one of my favorite genres, and this one really satisfies. I didn't think it would touch Ghost Recon 2 (my console favorite), but I have to say it holds up nicely, and in some ways excels.
The squad control is very detailed, and the delayed actions are a nice touch, but don't quite to far enough. For example, you cannot have a squad member perform any grenade actions.
I've not tried the online play yet, as I'm still finishing the solo campaign.
Overall, however, I have to recommend this, especially for fans of fairly realistic (as opposed to arcady) squad shooters.
