With the launch of "A.V.A" in 2007, Redduck became the first Korean studio to release a game powered by Unreal Engine 3 in the Korean market. The game was subsequently released in Japan, the U.S. and China, and received wide recognition for the quality of its graphics and its intense military battle scenes.

"With 'A.V.A.,' Redduck proved its ability to create a world-class game," said Ray Park, territory manager of Epic Games Korea. "Plus, the game was innovative - their system for in-game commerce was one of the first of its kind. We're thrilled that they're using Unreal Engine 3 again for 'Metro Conflict: Presto,' and can't wait to see what they're able to do with it this time."

"Epic's Unreal Engine 3 was a big factor in our success with 'A.V.A.,'" said Do-Min, Ok, Redduck's chief technology officer. "We're looking forward to pushing ourselves even further with 'Metro Conflict: Presto,' knowing that Unreal Engine 3 has constantly evolved since we used it for 'A.V.A.'"
