Overall I like it.
I wish the graphics and sound were more polished, but this isn't the finished thing so that can always improve. I wish every class could stealth, not just the sniper class. Is it possible to counter the UAV somehow? If the other team has one you seem to be screwed.
I really like the squad dynamics and the ever changing random objectives. The cover system is great - just like the last splinter cell or the previous advanced warfighter games - you can see a spinning circle of other cover points and can rapidly transfer between them. Anyway, it's fun and I will dig into it more this weekend.
