After many years on the battlefield, I would say the game has kept me off the streets and out of trouble. Since it is a game of make believe, If you fail, you wait for a few minutes and try a new approach (unlike real life that might cost you everything).
* Forget about K/D and stats- Old players know it takes long hours to get half way good. Worrying about stats will make your life miserable when playing.
* Talk on the mic. You might be surprise some one will answer you. Some of the best games I had through the years was on a squad that talked. We sometimes had terrible scores at the end, but it was fun.
* Find the hiding places in the game. Most of the best hiding places I have found were by accident over a long period of time, it is built in the game.
* If you think this game is instant gratification
because you paid money for it, it is not. It grows on you over time to be fun, by trying new things during game play.
Any more suggestions out there?
