Battlefield Bad Company 2

So today I managed to get one Bad Company 2 beta key from Fileplay. And now I'm going to write what I felt after playing this beta for 2 hours. Battlefield Bad Company 2 is has a huge open world map obviously. In the game, most of the things are destructible. The sound is quite good overall. You can heard the sound firing from distance, when the tank shot a 'rocket' toward you or nearby wall where you are standing, and you will heard something like what you should heard when there is a impact hit at your ear.

In this beta, only one mode is available and that is Rush mode. In the rush mode there are two teams, one is defender team and another one is attacker team where you will need to arm to detonate explosives on a defending team's crates. Until now, I'm not so sure about the game mode yet, I just join the game and keep shooting at other players.
When you join the game, you need to choose a class before you can enter the battlefield. There are four classes which are Assault class, Engineer class, Medic class and Recon class. Each class has their different weapons and advantages. Each class has an initial primary weapon, hand grenades, sidearms and also a pair of gadgets unique to that class.
Players will need to gain experiences through every match to unlock new weapon and gadgets. Those weapons and gadgets unlocked are only usable for the specific class only, and not every class can use it. Those experience can be obtained by performing actions conducive to the goals of the player's team, such as eliminating enemy players, healing teammates, or capturing or defending points of interest. Bonuses to the base number of points can be awarded under certain circumstances (such as achieving a headshot in the process of eliminating an enemy player).

I felt that its hard to kill a player by using my rifle, may be its because of lag? Or may be the damage shoot by the gun isn't much. Almost every players, I have to shoot 16++ bullet to kill the player. [Maybe I accuracy was pretty bad?] In each game, I hardly killed more than 10 persons but only get assisting point. The map is too huge that sometime you don't even know where your opponents are and you keep get hit until you die then the kill cam show you where your opponent is.

I run BFBC2 in medium setting with Asus 8600gt DDR 2 graphic card which still looks great, but for the latency, I don't know how much is my latency. I think there is a little lag in the game[for me]. Maybe it is because of where I live?.

I will still do some 'research' for this BFBC2. Well its quite fun if you play as attacker and using the sniper class. The sniper bullet will drop if the shoot it at the very far distance so you will need to adjust or estimate your aiming before you fire.
