It looks like a cheat. Right before you see the peacekeeper, he takes out a type-25 and after a split second it transforms into a peacekeeper.
yeah it's a hack they used a program called Cheat Engine and found the Address for the gun and create a class for the first class. all you have to do is google this and you will read where they say it only works fir people with Season pass and there is a high risk of ban etc.. these people are losers who deserver the ban they get.
Thank you for the info, that clears alot of stuff.
