It's allright. It's fun if you can mentally get past all of the obvious problems.
Pros:
- Interesting cover system often not seen in most popular shooters
- Campaign is fun, and co-op is even more fun
- Has in-depth customization of your character
- Experience points and rank ups carry over from campaign to online
- Has Terrorist Hunt mode so you can fight enemies just for the sake of fighting enemies
Cons:
- Multiplayer has broken gameplay and players abuse cheap tactics
- Customizable camoflauge patterns aren't unlocked untill the very last rank
- Doesn't have a great sense of realism because of ridiculous customizations
- Gameplay is repetitive and boring
- No one uses the taking cover system online
- Matches are hosted rather than a matchmaking system so there is a host advantage
- The audio sounds like it's from an old James Bond movie
- First person character models and weapon models are unrealisic and cheesy
