The fourth patch for Assassin's Creed: Unity will roll out today on Xbox One and PS4, and it's due to hit PC later in the week. Ubisoft has said that the fourth patch for Assassin's Creed: Unity will fix "most of the remaining issues" in the game, weighing in at a whopping 6.7GB.

"Part of the team's effort to enhance frame rate for players involves replacing and updating portions of the Paris city map where we are seeing issues," Ubisoft writes in a blog post. "This explains the large size of this title update (6.7 GB). However, since a large portion of the patch replaces existing files the net increase to the game's overall size will be less than 6.7 GB."

Patch 4 addresses performance and stability (framerate drops, lost progress and game crashes), gameplay (navigation and lock-picking chests), and online issues (connectivity, matchmaking and the companion app). The patch was supposed to launch yesterday, but Ubisoft delayed it to refurbish the Paris map.
