I previewed ARGO recently, and here’s the official trailer revealed at G★2009. ARGO is developed by Mgame, known in the English market as Netgame. The team behind ARGO also made Scions of Fate (Yulgang). ARGO is being touted as a “hybrid MMORPG” due to its playing style. So, here’s the trailer introducing the various classes, including some gameplay footage.
Update: New trailer featuring the features of the game.
