I've been playing this for the past few days. Originally, I bought it on the 360, but my console decided to do the '3 red ring trick' on me. I was quite enjoying it, so I bought it on the PC.
There are some annoying kinks. There are no Dedicated servers, it's all done via P2P, near enough the same system as MW2, even with host Migration. This is something I can live with, pings seem stable and I haven't had any problems with games that lag, so far.
The one thing that annoys me, and others I'm sure is the fact that you can not join a session in progress, effectively once the game has started the doors are closed, so to speak. It creates a rather silly problem, if someone leaves, they don't get replaced. So the teams can become very unbalanced. This also has a knock effect when looking for games, as the system will only look for current sessions that are waiting to start, thus searching for a game and getting into one for that matter can take a while.
Unless I'm missing something, there are no graphic options, well, actually I lied, there is one! It's a shader level which goes from 0 to 5. Oh and resolution. That's it.
The key bindings are crap, and you'll need to change them instantly. Oh, and also there's a little thing called AIM ASSIST! Really, why is it even in the game, god knows. This is a PC game not a console game. I've turned it off, but in close combat I'm sure AA has the advantage.
There are some good points to this game, depending on how you see it, of course. It could be considered to be quite hard. You'll take a few bullets then die, you can not run and gun, you will miss, you will die. Camping, although people seem to do it, is rather pointless because you have a X-Ray type pair of goggles that allow you to see the enemy through walls. This can create some tense situations and also help with some nice multi-kills.
The weapon customisation is crazy, you can do so much to your weapons I won't bother typing it. You level up, just like MW2, you'll always get something, may it be weapon camo or upgrades.
Maps are tight, and have a lot of bottle necks, you'll never be with out combat due to it(and the goggles)
I'm going to stick with it and see where it goes, at the moment I'm enjoying it.
If you are looking for a new shooter and can look past the cons, maybe this will be for you.
