Overall, I'm pretty impressed. All of the maps that I've played, excluding the few Titan modes, were 64 player maps. And they were pretty damn big, excluding Port Bavaria which is just a bit smaller. So far, I've earned a couple Assault Line Attack pins, the Gold Arctic Combat Badge, a Vehicle excellence badge or two (can't remember if I only have bronze, or if I got silver) as well. I think I have the Operation Snowflake ribbon, but I don't remember. So, as a Field Commissar Silver, I have more items unlocked than a Field Commissar Silver without Northern Strike. Yay for me. I'm not going to talk about the unlocks, as that's been discussed many times. Also...for some reason, the Cold Front Unit Service ribbon hasn't been awarded to me, even though I've met the requirements multiple times. Big surprise there.
My only complaint so far is how easy it is to get killed while in the speeder. I'm not talking about the speeder getting destroyed easily, I'm talking about some lucky bastard placing several very well placed shots while I'm driving. I can't count the number of times that I've died while my gunner was still alive. That's not a fault on DICE's part, just something that's frustrated me a bit. I've gotten killed less while gunning opposed driving.
Also, you get an unlock every time you get one of the new awards. What doesn't happen though is the option to pick your unlock at the end of the round. For some reason, it just doesn't show up. So...after playing for a while and earning multiple awards, I was starting to think that you only got an unlock when you recieved the Gold badge instead of Bronze, Silver, and Gold. After a session, I disconnected from the game and noticed at the main menu that I had several unused unlocks. So...for whatever reason, you do earn unlocks for every award (excluding the pin), but you won't be able to choose them unless you go to the main menu and pick them there. Not a big deal, just something I've noticed.
The last thing I should mention, which I'm sure many are already aware of, the EA Stats page hasn't been updated to include the Northern Strike content. Wonder how long it'll take EA to remedy that.
