Ascend: Hand of Kul, a 2013 Signal Studios free-to-play action RPG for Xbox Live Arcade, featured innovative asynchronous multiplayer where players influenced others' worlds through "ghost" interactions. The game, noted for its "asynchronous multiplayer" and grand scale, became unplayable upon server shutdown in 2014, leading to its continued discussion in Jtag/RGH modding communities for preservation efforts.
