Seems like we missed this when it was announced a few days ago—OnNet USA has announced that its free-to-play title Manga Fighter (on the GamesCampus portal) is now going to allows non-paying players to earn "Don" (the world's in-game, micro-transaction credit) through in-game achievements, meaning they'll be able to purchase items in the game's item mall without having to spend real money.

The promotion lasts until the end of March, and Don can be earned by playing matches, allowing them to purchase previously paying-player only items such as guns, melee weapons, throwing weapons, launcher weapons and skill cards.

"The free-to-play micro-transaction model is sometimes criticized for not providing a level playing field for both non-paying and paying players," said David Chang, Executive Vice President of Marketing and Business Development for Gamescampus.com. "We wanted to offer the opportunity to allow Manga Fighter players who do not have the means to spend real money on these items, a chance to earn them through their gameplay.''
