Ubisoft has suddenly restored server functionality for several older games. Multiplayer mode has become available in the games Driver: San Francisco, Tom Clancy's Splinter Cell: Blacklist, Rayman Legends and Assassin's Creed 3. According to information from members of the TrueAchievments portal, players are now able to obtain achievements that are only available in online modes.
Officially, the servers of all the mentioned games were closed in October 2022, but from time to time they returned online for short periods. At the moment, apparently, another period of their activation has begun.
It is likely that this sudden activation of the servers is a temporary phenomenon and they will go offline again in the near future. Therefore, those who are eager to complete multiplayer-related achievements should hurry while the servers are available.
