The PP-2000

The PP2000 is one of the most powerful weapon on the game. It only has 21 rounds but the magazine capacity does not matter, this gun can kill at least 4 guys spraying. If you snap the silencer and you are a beast. You'll kill everybody. The PP2000 was a secondary on MW2 but then on Battlefield 3 is a Primary so I looked the PP2000 on the internet and it was a sub machine gun so I am happy that it was put on the right place
