It’s been a while since we’ve heard any news about CJ Internet’s MMO action-fighter, Mini Fighter, but things have changed since we’ve interviewed the company back in August. The closed beta has ended, and the game is now open to the public, with a few new tweaks to make the game tighter.

Based on feedback from the closed beta, a number of improvements have been made to speed up loading times for low bandwidth users and improve overall performance. Characters and leaderboards have also been reset, so the only advantage players can carry over from the closed beta is the experience they gained in the game’s various battle modes. Some knowledge from the head honcho:

“We want Mini Fighter to be the most action-packed experience it can possibly be, and we believe that listening to our community is the best way to make that happen,” said Youngjong Jung, President and CEO of CJ Internet. “We invite players both new and old to join the Open Beta and experience the online brawl firsthand!”

That experience could be important, however, because the first Mini Fighter Battle Championship is scheduled to kick off in early January. Players who want to test their skills will be able to compete in three-on-three Team Battles or one-on-one Grand Arena matches, and winners will walk away with up to $4,500 in prize money.

Registration for the Team Battle matches opens today, while qualifying rounds for the Grand Arena matches will take place at the start of the championship. For more information about Mini Fighter and to join the Open Beta, please visit the official website.
