Rainbow Six

If you do not use an entire clip but are low, change your clip. The game will not use up one of your extra clips, but instead simply reload your clip in use. Note: This may not work for pistols.

Always check your radar for terrorists before entering a room. Terrorists turn red arrows on radar.

Do not leave without a heartbeat sensor -- let one operative have at least one.
