First and most importantly, A SNIPER NEVER PULLS OUT HIS SECONDARY! When two snipers are going head to head, it's between those two SNIPERS. If one of the snipers gets a hitmarker on the other sniper, he should not pull out his pistol to finish him off. This goes for the same for the sniper that was hitmarkered. If you are sniping and you get hitmarkered, you cannot pull out your pistol either. Just continue the sniper battle and may the best man win.

Second, the ONLY time a sniper can pull out his secondary is if he hitmarkers someone that IS NOT sniping! This one is pretty self explanatory. Having an enemy run up on you using an MP7 or UMP45 while you're sniping can be pretty frustrating.

Third, if the last two people left from both teams are both sniping, it "officially" becomes a quickscope battle. This is when the rules above come into play.

Fourth, if you are sniping and you are the last one left, snipe and kill all other enemies. When only ONE enemy is left, try and make it something fancy. This is regardless of if the last guy on the other team is sniping or not. Now I'm not talking something like a "720-ladder stall-silent shot". But maybe like a 360 quickscope or double tap Y or triangle (depending on your system). Just to make is something visual appealing to others. Not to mention, if it's good enough, you'll have the whole lobby jaw dropped over it.

Fifth, DO NOT HARDSCOPE FOR THE FINAL KILLCAM! Talk about a major "face palm" when someone kills you and in the ENTIRE killcam, they are in a hardscope. It's just embarrassing to be quite honest.
