Nexon, a South Korea-based gaming company, has invested an undisclosed amount in US-based game development studio Robotoki.
Robert Bowling, former creative strategist at Infinity Ward, founded Robotoki in April.
In June 2011, Nexon provided funds for the newly merged social gaming company 6waves LoLapps, the maker of Resort World, just ahead of its own flotation in December after receiving corporate venturing backing itself.
