Black Myth: Wukong will be a unique account of the Chinese tale Journey to the West. We see the main character, Sun Wukong, in a unique setting that closely resembles Sekiro: Shadows Die Twice and contains several Soulslike-type mechanics. The announcement of the game came with a short 13 minute video showing some gameplay footage. We see Sun Wukong spinning his staff to deflect attacks, sneak behind enemies with a charged strike, and take on a staff based opponent who has had unique attacks. Because many compare it to various tough single player games, does that mean it won't have multiplayer?
At the moment, it is probably too early for us to tell. Developer Game Science could add minor elements similar to how players have had multiplayer modes in previous Soulslike games. For example, in Dark Souls, players can be swarmed by others when logged in online, and their main character has a soul in them, which gives them extra health. There could be a similar mechanism. If you visit the official Game Science website, they say they don't have any current comments regarding an online mode, but the hosted action game does support network combat. The team probably hasn't commented on it, at least not yet.
Game Science does not have a release date for Black Myth: Wukong. However, on their website, they list that it won't take them 500 years to complete it. However, the team will not release any specific details about it until they are happy with the product. Everyone at Game Science is probably a lot more focused on creating an authentic game with diverse environments and engaging in boss fights before entering the confines of a multiplayer mode.
