In both instances, the game client itself just looks for (and finds) Battlenet on its own. And obviously using SC2Switcher_圆4.exe while the system is connected will do the same thing. I can confirm that launching SC2 from an offline BDA while the system is still connected to the internet does not work. I got the exact same results with the executable as when using the BDA. I clicked “Play Offline” and the game opened:.My account address was already filled in (I removed it for the picture): Eventually, it moved on to this screen.When it launched, it sat on this screen for a little while, probably looking for Battlenet: I clicked the “Play” button to launch SC2.I just gave this a try and was able to play offline. I would happily install a patch disabling all online multiplayer if it meant that I could get rid of this always online requirement. Some of us who purchased the game would just like to play the campaign because we were fans of the campaigns in SC and SC:BW. And, apparently, this is a known issue from as far back as 2017 that still hasn’t been fixed ( ). Really disappointed in this DRM tactic, Blizzard. As a result, I don’t get to play this game I’ve purchased, and, instead, have to waste my limited downtime asking Blizzard for permission to access the game. However, every time I try to follow Blizzard’s guide on how to play offline (for up to 30 days), I get a message saying that I need to have been online to authorize my account (was online yesterday), have a character account with purchased content (I have no idea what this means, but I bought the Battlechest with all 3 campaigns), and I need all the files installed locally (which I always default to when installing a program because I don’t want to have to deal with issues like this). I had a limited window of time today to play SCII before work, but it just happened to be during the maintenance, which SHOULD NOT be an issue if I’m just trying to play the campaign. I’m also unable to play the game offline (for a different reason), and I run into the same issue whether I use the launcher normally or the SC2Switcher_64 executable.
