WOW
I have to admit that I'm not too far into it and to give it a rating of a 10 already has to speak to what it offers. I played for about 1.5 hours online coop with a buddy and about 1.5 hours alone and both modes were a blast. Playing with a buddy allows you to discuss how to breach an entry in the most tactically efficient way, while single player allows you to think on your own and position your players most effectively. What's fun (like in R6V1), is you have time to think it through. I enjoy actually sorting out the obsticale and then deciding the best approach to take. A blast.
What I didn't expect wast the upgrade to the PEC concept. You gain experience points/rewards through both online play and by yourself. You are rewarded for stuff like headshots, sneaking behind for kills, etc. It forces you to 'do a good job'. It reminds me of COD4 online play in how it rewards you, but takes it further by combining the online reward concept with single player campaign.
Like I said, I've only played it for a total of about three hours or so, but I'm pretty sure I'll be hooked for a least a month. Saying that is saying a lot as I typically chew through games pretty quick. I've played recient releases such as The Club and Army of Two and invested some significant time in them (check my gamecard if you want to look at achievements) and those were good, but not like this.
Shooters are typically pretty basic concepts but this has so much to offer beyond the basics. It's humorous that the few early reviews such as XPlay have dogged the graphics (XPlay that rates crappy DS games and WII games well (man that show sucks these days)) . The graphics are more than good enough, plus imo, gameplay is always > than graphics. I would imagine that you will not see the graphics as a downslide as they are just fine.
In summary, this game, especially if you liked R6V1 or Gears is one to get. It's been my experiance that it typically takes me a few hours to really start to enjoy a game (Ao2 is a perfect example). This game quickly illustrated that it has what I love in a game and will be worth playing for a long while....
Get it.
