Nexon recently got tangled up with the Fair Trade Commission of South Korea as it failed to disclose the gacha draw percentage in two of their games, namely Counter-Strike Online 2 and Sudden Attack. The case dates back to November 2016, when Sudden Attack users had to buy an assortment of loot packages in order to gather 16 jigsaw puzzles to form a full image of celebrity for an in-game digital prize.

The Fair Trade Commission concluded that the draw rates for some jigsaw parts were as low as between 1.5% and 0.5%. Using the findings, Nexon was accused of cheating consumers. Reports state that Nexon is being fined on two separate charges with penalties of USD 5,000, and USD 900,000, although it it intends to fight the case. On 1 April 2018, Nexon announced that the percentage chances to obtain an item in all its games with the gacha system will be published.
