Combat Tips

[Holo]

As I've played PlanetSide these past weeks there is something that is becoming painfully obvious to me... I really suck at this First Person Shooter thing I come from a game called Infantry and it's an overhead style game so I'm really kind of at a loss when I go face to face with Counterstrike players and Tribes players... But I'm sure there are a few fundamentals to fps combat that I am just unaware of, so if you guys would be kind enough to enlighten me on some of the dos and don'ts of fps combat I would be most appreciative
