South Korean musician and "Gangnam Style" creator Psy has invaded Nexon's free-to-play Korean titles MapleStory and Combat Arms.
MapleStory is a massively multiplayer side-scrolling game where players defeat monsters and develop their skills. Psy began appearing in MapleStory as a special in-game character on Aug. 21. Players can complete missions to rescue him from an alien abduction or help him get ready for concerts. Special items, such as a Psy ring, are also available from different events.
Combat Arms players can access Psy-specific content today. Check out the teaser trailer above.
Nexon's Psy promotions are not available in North America.
