I've been playing a lot of the Bad Company 2 beta recently in anticipation of the March 2 retail release. Here are just a few things you can do to have a better experience. 

Teamwork

Vehicles

Common Courtesy

" If you see someone repairing a vehicle, don't jump into the driver seat and run off with it. "

  I would wear a mic more if they weren't so irritating.    

Good tips.

oscar mike.

I played it for the first time last night, its awesome feels like killzone2 and just enough of cod, I love it. I'm going to be a regular..... on MAG too can't just pick one. 
 
also good tips thanks,  I've had so many people drive off while I'm repairing vehicles on MAG too, so annoying.

" @natetodamax: Whenever I hear someone on with a Mic, they're either complaining about other people on their team for not working together or complaining about the other team for 'hacking'. So in other words, I agree with you. "

Well, when I said irritating I was referring to how uncomfortable it is to wear a mic while playing. But yeah, I also don't want to hear the old "OMG HACKERS" complaint. "

Most importantly - have the decency to use squadspawn more often than not. Teamwork ensues. The game's pacing improves tenfold. Can't tell how much having players not using squadspawn does hurt the game's pacing and teamplay. I just don't get some people. How can somebody not spawn on me, when I'm at the perfect vantagepoint on a crate? I'm so grateful for players using squadspawn. I'm grateful for players surviving long enough to offer a good squadspawn for me. I'm grateful for good fucking squadplay.
 
No squadspawn. No squadplay. So use squadspawn please. Please.

Yes on all points, and I might have a few of my own.  

• The UAV is for spotting, the more you shoot with it, the greater chance someone notices you and shoots you down. (Exeption beeing enemy helicopters, with alternate weapons package, you take them down easily).   
  
• Ammo, throw one out as soon as you spawn, then others where needed. Beeing out of ammo sucks, and assaults seems sometimes to forget they have the kit until they run dry themselves.  
  
• Stationary ATs is every tankdrivers worst nightmare. (Believe me, I have spent days worth of time driving tanks in bfbc). They hit harder than rpgs, never runs dry, and in this game, respawns. So if there's a tank rampaging around your base, get to one.  
  
• You have a parachute. There's no excuse for falling to your death.

These are great tips for newbies to the Battlefield franchise, like myself here, who's been really enjoying the BF:BC2 demo. Thanks!

Also, with the UAV, don't just fly it up in the air over the battlefield and get shot down in a second. Try to hide behind cover, trees are an excellent source of cover for the UAV, given it's size.

Totally agree with all points. When using a tank I always hang back abit and just spot and kill enemies, which is so much more benficial for the team.

Remember you can harm copters using the tank gunner seat and you can take them down using it.
 
Oh yeah, take down the UAV whenever you can!  UAVs can be very harmful in the right hands.
 
Also, if your squad is down and you are deep in enemy territory, try to find a safe spot and let the team spawn on you.

Question!
 
On the Attack Chopper RB is like an anti tank missile.
Can this thing be guided?
If so, how?
 
Also if you are flying a helicopter and a pesky UAV is chasing you, the best way to take them out is to fly to where the UAV box is and just get your chopper gunner to shoot him!

i was about to post a thread about how the demo is kinda keeping me away from the game at times.. I love the demo to death I play it all the time, But I have yet to find any decent squadmates that give a damn about the squad system. Everyone just wants to be a hero.  
 
Everytime the team spawns to the areas where the choppers are they jump in by themselves and take off. The choppers are no good unless they are being used to their full advantage.  
 
No one has a darn mic either!! the only time I hear a mic being used its so someone can play their music or just breathe into it. I have a mic but I don't even use it because when I try and let others know about a location of an enemy or anything they don't pay attention and run off.  
 
I don't even use my mic anymore for that reason that no one else has one. If there are some Giantbombers on here that want to play the true tactical squad based way then add me on PSN my id is the same as on here. 
 
see you guys on the battlefield!! 

You made a lot of good points and that is why I am getting pumped up for the game.
