Rating mainly refers to the single-player campaign:

Some points that bothered me:
- The stupid AI colleagues who run a in the line of fire, a search for the cover in the way, or anywhere (. Eg on columns) stuck
- The insanely bad destination "Help", which I have issued after the second mission
- Railings, glass panes, etc., ensure the perfect opponent coverage
- The predictable story that Bad Company nowhere near the water can range
- To copy the lack of imagination and audacity of developers, certain situations almost completely from other shooters (eg CoD MW)

Plus points:
+ Graphics, sound, sequences

Conclusion:
I have only used the game fortunately bought (6), otherwise I probably would have annoyed me more than the half-baked single-player campaign. If you want to only play the single-player mission, the be advised to do the same.
