Halo2 XBox tip details

Twitch-fire the plasma rifle and needler.

The plasma rifle and needler can both be fired more rapidly and accurately then their fully auto modes simply because of the fact that they can almost litterally be fired as fast as you can pull the trigger. If you learn to twitch your finger on the trigger while firing you can nearly fire as fast as the plasma turret. This is why elites and grunts with plasma rifles and needlers can fire them so irritatingly fast and accurate.
