Modern Warfare 2 players are paying real money on eBay to unlock a hard-to-gain weapon in-game.
The M13B Assault Rifle is contentiously locked behind a challenge in Warzone’s DMZ mode and is a massive pain in the bottom to complete.
However, players have also found a neat trick that means that only one person in your group of friends has to complete the challenge. That player can then “drop” the weapon for other members of the squad to pick up, extract, and unlock.
