Cire- it's 11, but I got it through the care package. I unlocked the harrier and have been getting it quite regularly. That's 7 I think. Predator Missile is pretty great. I'm also around 20 or so. I got a pretty long kill streak with the AC 130. Switch to the middle sized gun and go to town.
Things different from CoD4- The game play and controls are pretty similar, thank God. But the maps are much more involved. There's always some form of high ground. You can get on roofs, etc. alot more frequently. Also, the environment is destructible. Customization is out of this world. Each gun has 7? attachments and 5-7 paint jobs. Each with tons of challenges. The perks now have a pro version that unlocks a better perk (Get so many kills with Stopping Power to unlock Stopping Power Pro which increases damage on vehicles). The callsigns seemed useless at first, but there are a few hundred Titles to unlock so it's fun to see what everyone has. You get points for everything. Multikills, shooting down helicopters, even stupid stuff like reloading the most times in a game or looking through a scope for the longest time. Graphics have definitely been improved. The blood splatter effect is awesome, and when an explosion occurs near you, you get a mud splatter effect. Nothing really influences gameplay, but it makes it so much more submersive.
