Battlefield Bad Company 2 is a game which will never fail to excite you.
In Fact, not at all. Bad Company 2 is not just any shooter. Not only is it better compared to its predecessor BC1, but it is also a general improvement in the genre. Especially the Multiplayer experience is extraordinary.
In addition to that, all the Graphics and Physics have been upgrated quite noticably. Now you are able to demolish entire buildings, and the explosions look better than ever. Bullet physics have also been added, something which affects profoundly the gameplay especially for snipers. You now have to calculate your shots depending on the distance you have from your target.
Textures and animations are also great, but what makes the game special in the audiovisual section, is its Sounds. They are by far the most realistic, the most badass, the most...the most...the most... aahh, i can keep saying stuff forever...anyways, after playing BC2, any other game will fail to impress you equally.
The singleplayer experience is quite good, but nothing that noteworthy. Though there are moments which will aphyxeate you.
Now the multiplayer... Basically there are 2 basic gamemodes with some variations. Rush, and Conquest. Both of them are made in such way, that will keep you amused for a disturbing amount of time!!! The maximum number of players is 32, and believe me, in this game, 32 players = massacre. Vehicle combat has also been intensified in this game. There are Tanks IVFs UAVs Boats Helicopters which can all be devastating if used appropriately.
To conclude, I would reccommend this game without any doubt. You will find it better that most shooters out there. The only thing better than this would be to imagine how Battlefield 3 is gonna be (already in development)
