BFBC2

Bad Company 2 is now a must. It is probably the time one of the most played videogames. I can only say positive for the game itself; the single player is very well done, the story is nicely done and the missions are varied; so the player's time in the jungle, sometimes on snow-covered mountains. However, the single player is just a small part of the game, because this unfolds his game right until the online multiplayer.
Here many players are playing at the time and there are some variants (Rush, Conquest ...). The weapons and classes themselves can be leveled, so you play freely and for weapons and attachments.
Even better is the game when the add-on Vietnam still buys. There struggling Americans against Vietcong in Vietnam; including all authentic weapons and vehicles.
All in all I can only recommend this game, it is at the moment probably the absolute reference among the first-person shooters.
