The only catch is that there’s no option to split parties between both local and online.
Again, parties of up to four players are supported. There’s also the option to play local couch co-op.
Up to four players can join a single session through online matchmaking. Given that the game is available on Xbox Game Pass, there’s likely to be loads of players jumping into the action. The news is good: Anyone who buys The Ascent will be able to enjoy online co-op with friends. However, there’s no true cross-platform play, as the game isn’t available on other platforms like the PlayStation 5. In addition to couch co-op and online multiplayer, The Ascent also supports cross-play between the the Xbox Series X|S and PC.
