after playing multiplayer since release i have found a lot of people cheating with 1 hit hack but also recently found that if you put rapid fire on the shotgun it almost always 1 hits enemies at resonably close range so i stopped using it makes gameplay boring

.. but i have also noticed a lot of other players have realised this too and now the game is turning into a shotgun fest

certain clans are exclusively using upgraded rapid fire shotgun as main weapon and making it very boring for others .i like a fair play for all its bad enough with game laggs and cheats without stupid 1 hit weapons even with full armour you just get fragged every time

upgraded rapid fire shotguns? Im assuming you're referring to the jackal... And in any case - jackal is 2 shot minimum for me - only marshal takes 1 shot to kill
Yeah the Marshall is a 1 shot kill when the hit detection actually works
