First off this is THE FPS game to own. So, if you want to run and gun this is for you. I like military shooters!
First off the good
1. The story mode was short (if you blazed through the easiest difficulty), but it has solid replay value. For one finding intel pieces in the game unlocks cheats, and re-playing levels on veteran mode will challenge the most skilled players
****spoiler****
2. The story has enough drama (for dudes at least), action, and progression to keep you sucked in; however, the best part is that the single player story is a mere training camp for the multiplayer masterpiece.
3. I paid $40 for it (at eBay), it can be had for less than $20 now, a great addition to any collector
4. A fair amount of weapons and varied roles (SAS vs Marines) keeps things interesting
5. Excellent multiplayer with a ranking system that literally pulls you in (I have played for 13 days total time and am on level 6 prestige)
6. Challenges that keep you progressing through the various weapons maps and perks
7. Soundtrack and graphics were awesome, only after 6 mo do they grow a bit old
8. Headset support is good, but the ability to mute others in the lobby (and during game loading would be great)
9. Wide array of setups (LMG, SMG, Sniping, Shotguns, Assault rifles)
10. Sweet sounds (with this hooked up to a good stereo you can feel the blasts, hear people approaching you, claymores arming, etc)
Now the bad
I am not 100% on how the host is picked, but this needs work, I mean most matches online I would place in the top three (towards prestige mode 4), but occasionally I would only get 2-3 kills
With 1 bad and 10 good this game gets a 9.5/10. It is worth playing if you are a FPS fan, especially if you love FPS games.
