One of the original selling points for Watch Dogs 2 is the "seamless online experience", where the game would connect you to other players for online missions, bounty hunts, and hacking invasions. A problem was found during the review period for the game, where the seamless online would cause performance issues and crashes. Ubisoft took the mode offline to fix it, with the intention of having it live for launch.
That didn't happen. Instead, Ubisoft is still working on the fix.
"During the pre-launch phase of Watch Dogs 2, we were disappointed to discover an issue tied to the seamless multiplayer feature that caused the game to lag and crash periodically. In order to eliminate that issue at launch and for players to enjoy a smooth game play experience, we have decided to wait to launch the seamless multiplayer feature so it would not impact the core gameplay experience," Ubisoft said in a statement.
"To be clear, players can fully enjoy the entire single-player experience without any concerns. Additionally, co-op is still fully functional by inviting friends through the game menu. However, the Bounty-Hunter mode and other activities that would occur with other outside players who enter your game will be unavailable until the issue is resolved. We truly appreciate the patience of our player community."
I'm sure many will have no issue with this, as single-player is intact and multiplayer is still available with friends. For my part, I didn't have any issues with the game while seamless online was active. I was invaded by one player who tried to hack me, leading to a cat-and-mouse chase where the other player did their best to hide while I hunted them down. I beat them to death with a billiard ball before their hack completed. It was fun.
Watch Dogs 2 is currently available for PlayStation 4 and Xbox One. It will be available for PC on November 29, 2016.
