One hit kill with pistol
There's a glitch where if you get a regular halo pistol (NOT a plasma pistol), and shoot someone directly in the head once, theres a small chance that person will die instantly! This is due to the shield sometimes not being able to catch up with the latency (time it takes to register what is happening to players), so you will sometimes get a little 'lag period' where the players don't actually have a shield. It will work even if the health and shield strength is set to 400%! However, I still don't know why no other weapons do this...
Also two other tips: this glitch will only work on multiplayer and servers with more latency time will be more likely to experience this glitch.
