Ghost of Tsushima won’t be receiving any more planned patches, as confirmed by Sucker Punch in the notes for the most recent patch.
The patch notes mostly focused on bug fixes and item adjustments for the standalone multiplayer game Ghost of Tsushima: Legends.
Earlier this week (April 12), Sucker Punch released patch 2.18 for Ghost of Tsushima, and according to the developer, it has no more plans for patches.
Considering Ghost of Tsushima came out almost two years ago, the fact it isn’t receiving any more planned patches isn’t too surprising, though considering Legends is an online game this likely isn’t the last patch.
