Blade47167 - This is a game that, IMO, has a little bit of a steep learning curve because of the different control schemes between tanks, jeeps, WH's, troops, dropship etc. It can be frustrating for a while if you're playing in games with seasoned players. I got a friend into it and he's been playing for about a month still learning the controls and getting fragged a ton. But the trade off for it is that once you get real confident with what your doing it becomes a very satisfying, fast paced thrill ride of competition and teamwork. I can't blame you for enjoying COD4 so much, it's just as top-notch as this game. When did you stop playing? There were some ranking bugs (that only recently got fixed) that caused newer players to be in servers with legitimate high ranked players. It's also helpful to troll the servers with the "my rank only" filter "ON" when starting out and maybe stick to only one game type at first when learning. As for the machine gun...I think it takes about a clip and a half to kill someone, while the grenade can be anywhere from one to two depending on accuracy. I'm sure any of us would be more than happy to give you tips if you need.
