NetDragon Websoft Holdings Limited announced that Under Oath officially launches its open beta testing on all platforms on 9 December. It is a brand new ACGN IP mobile game developed by NetDragon, and is exclusively published by bilibili game. Under Oath represents yet another new IP after NetDragon's other flagships, including Eudemons, Conquer Online and Heroes Evolved. As a next generation JRPG mobile game, Under Oath uses a well-elaborated plot to depict a world of Gods against Demons, with the storyline focusing on how the protagonist and his friends go on an epic adventure. Each character is designed with over 30 combat moves, and each move has its own graphics to support a refreshing and appealing battle scene. On top of the above, its battle mode also underwent a complete revamp, as players will now enjoy greater flexibility in use of skill, changing character, as well as CD control, which will add further complexity to each round of battle, all leading to exceptional players' engagement.
