I've always thought that Starcraft 2 was Always Online, but I was talking to a college today and I found out there was an offline mode which just lacks access to achievements or custom maps (like I care for either).

I've boycotted StarCraft 2 when I read that it was Always Online play because I don't want my main gaming powerhouse connected to the internet.

So does StarCraft 2 require any net connection to start a single player game? I'm not going to waste money to buy it only to learn I can't play it.

Starcraft 2 can be played offline, as long as you have logged in at least once.

Attempting to log in without an internet connection will give you the following screen:

Screenshot of "Can't Connect to Battle.net" prompt

Playing "Play Offline" at this point will allow you to:

  • Play all Campaign and Challenge missions.
  • Play Custom Games vs. the AI
  • Play Any Battle.net Arcade maps you have previously played (or can otherwise be found on your computer).

You will not be able to:

  • Earn Achievements
  • Earn Experience for your Starcraft 2 profile
  • Play LAN games, or otherwise invite anyone else into custom games.

  • when you say "as long as you have logged in at least once" you mean i still have to log in after a fresh install or can i just go offline right away cause i remember Unreal 3 having an offline mode to but i didn't need to even need to log in to get it's offline mode (but i did have to mess with some profile files in the filesystem to save the game)

  • @Memor-X Not sure what is unclear about that? You have to log in once. Commented Mar 12, 2013 at 4:17
  • @MatthewRead probably more a sense of clarity on weather the log in has to be successful that first time or not

    @Memor-X It has to be successful. It's essentially a one-time online activation. Commented Mar 12, 2013 at 11:15

I was able to play SC2 offline all the way up until just recently, the last update seems to have made it where you have to connect to battlenet and authenticate your game, which is extremely annoying because my internet doesn't always work good.


As of this posting, you cannot play offline... even if you want to play local games, and have logged on multiple times in the past, StarCraft 2 still REQUIRES you be online and log in to Battle.net, even to play in "offline" mode.

    Are you sure? the other answer seems to indicate otherwise.
