The developers of Ghost of Tsushima are no longer planning to release updates for their project, as the team recently announced . The same goes for the Legends multiplayer expansion, fans of which shouldn't expect content expansions either.
The last patch was update 2.18, after which the developers, if they release any files, then only to fix critical errors (if they arise). In a statement, the writers from Sucker Punch thanked all the fans for their support and for showing interest in their project.
Recall that Ghost of Tsushima was released 2 years ago and was popular with owners of PlayStation consoles.
