With the debut test phase starting in a couple of days in China, developer NetEase recently released videos showcasing in-game combat of 3 of the playable classes (video merged below). While not sporting a full non-target action combat system, the overall looks has attracted positive signs thus far.
With the flight system and character designs somewhat a mash of TERA, Aion and Blade & Soul, NetEase is apparently preparing Revelation for a launch in South Korea according to various news outlets. Not many people have seen the actual in-game UI and gameplay, so stay tuned for more info!
