Forum:Mystery Weapons?

When I was playing a few days ago i met a player level 50 who dumped out his dark orange weapons then left. I then picked them up (couldn't use them yet). Today I became a level 48 and began using the weapons and thought they were too good too be true. I then looked them up and they were nowhere to be found. I am concerned that they some hackers doing, and I will get banned from online play. Here are the weapons... This is three out of the five weapons. My computer is very slow and I could not get the other two pictures but their stats are as follows. The Devistating Mongol Damage:1096 Automatic rocket launcher 36 shot clip produces its own ammo Fire rate: 9 no decimal

Twisted Anarchy (Again) Damage:446 times 3 Uses all elemental effects Fire rate:152 (no decimal checked< same for other SMG)
