Does anyone has Bf3 Tips?

Hmmm, don't rush like a stupid idiot (like you do in cod....), check your corners when you are moving, Don't FULLY spray if you have an automatic weapon, burst insted, because there is something called SPREAD, which does NOT exist in cod.

Try all different attachment's to find "your" speciall attachment, to see which one you like the most. Try to use all different weapons aswell, ect ect.

My facourite is the M249, Foregrip, Extended mag and Kobra (RDS)

Unless your really good at Battlefield 3, you can't rambo in this game. There are no such things as one man armies, you have to use teamwork with your team. You do nothing alone, or you just make your team lose.

No camping like you do in cod as well because they will find you quicker than you can spot them, as they move in teams.

It's so easy to answer, don't even try to play it like a CoD game, also you're new to it and you wanna jump straight into hardcore? Don't be dumb to do that, you would just get destroyed.

I jumped straight into hardcore for the simple fact that whenever I snipe someone it sitll takes 2 shots to kill them even with m98. That is something that pisses me off unless you headshot them.

On my good days i can headshot running targets at 800meters. That shiz is awesome.

You know, THAT happens to me too, it's hardcore but still it takes 2 shot one kill with sniper, maybe one out of 5 is one shot on killl otherwise second shot kills them.
