After the successful launch of Arknights' global server's 1.5-anniversary event in 2021, Digital FUN teamed up again with the game's US publisher, Yostar, to produce a next-level live event for the game's 2nd-anniversary stream. With four sets of tracking camera systems and two virtual environments in Unreal Engine 4, we delivered an online celebration with more dynamic visual effects for the audience to experience immersively.
