I believe there is a lot for everyone to learn about this game. There are too many Call of Duty players that have picked up this game while they wait for MW3 to drop. If you’re going to play the game, please, learn how it works! This isn’t, nor will it ever be like, Call of Duty. This game takes real strategy, skill, and teamwork to pull off properly.

  • Start with the class you’re most comfortable with. You’re going to want to do well early on so you  can get better weapons as you move on, so pick what’s best for you. Later on you can switch it up  once you get a feel for how the game mechanics work.
  • DON’T CAMP, ESPECIALLY IF YOU’RE ATTACKING. I’ll never know why attackers feel the need to camp  back and pick their noses, but it needs to stop. No, I’m not saying you can’t snipe, but what I am  saying, is that you at least need to occasionally push yourself closer into the objective. On  defense, this isn’t near as bad, as obviously you need to partially camp to defend your objective. I  don’t advise doing this, as you’ll just get killed shortly after they realize where you are. I don’t  recommend staying in one spot for more than 3 to 4 kills.
  • Be aware of your surroundings. You sniping? Trying to pop someone in the distance? Well if you  are, be sure to pay attention to what’s going on right by you. If someone just got gunned down on  the other side of the way from you, HELP YOUR TEAM OUT. Don’t just sit there doing your own thing.  This is especially important if the objective is being captured/destroyed. Do something about it,  don’t just think, “Oh, someone else will take care of it.”
  • Fullfil your role. Playing Assault? Then please, heal your team mates and revive them. Playing  Support? Give your team ammo when they need it. I can’t tell you how many times I’ve needed ammo,  and every support guy in site that I try to get some from, just runs off and doesn’t care. Think  about your team, not only yourself. Playing Recon? Plant some motion trackers and maybe some mobile  spawns. Playing Engineer? Take out/repair some vehicles.
  • Do not pilot a vehicle if you don’t know how to use it properly. You will need to train yourself  to fly/drive things are some point, so either do it early on in your Battlefield 3 ranks, or just  let others take the wheel. And PLEASE, don’t just fly a chopper over somewhere and bail out if  you’re flying. You’ll most likely end up killing a couple team mates because of your arrogance.
  • TEAM WORK IS KEY. I’ve already addressed a lot of this stuff in previous points, so be sure to  read them and learn them.
  • Don’t just focus on one thing. Say you’re on your way to plant a charge on the M-COM station, you  see an enemy engaging in a firefight with a team mate. Stop for a moment to go help him, unless he  looks like he has things under control. You need to be able to make decisions on a dime, and weigh  the pros and cons of each action.
  • Cover is your friend. Don’t just run out in the open, take a strategic route to your destination.  A few shots will take you down, and if you’re seen, you most likely aren’t going to survive your  sprint.
Note: These tips may be added onto in the future. Also, these are mostly directed at those who play  Rush, so some things would be slightly altered for Conquest/TDM.
