Depends on the kind of environment your going to be playing, keep yourself the height of the cover your at when you are moving from A to B. Don't stray away from your team mates and just limit your angles of exposure so that your not being shot from all different directions. If your playing an indoor scenarios or entering any building ect. to move slowly and check your corners. When moving into a room go slow and smooth whilst only showing your gun and glancing down the sights with the rest of the body behind the corner. Move all the way through the door way to the next position. There's not really many things to think about for your first game, just get into it have fun.
