During this quarantine period my friends and I were messing around in the arcade and found a 3 player version of both the Wings of Liberty and Heart of the Swarm campaigns. Not only have the maps been altered and the difficulty adjusted, but there are plenty of new upgrades, research options, mutations, etc.
In the Wings of Liberty campaign, for example, you get three different options for protoss and zerg research. In missions where you play as Raynor, one person controls Jim while the other two people each get their own buffed up marine-like unit. In the Zeratul missions the other players control a “Zeratul’s apprentice” unit with their own unique abilities.
The Heart of the Swarm campaign was also incredible. One player controls Kerrigan, while the other two players control Naktul and Dowudiru. Each has a complete tree of upgrades, just like Kerrigan. Each mutation mission gets an entirely new strain, and each unit gets 4 possible upgrades instead of three. Overall, these missions are a blast. If you love the campaigns, you’ll love this coop version. I would highly recommend it.
Ive played it. Im a big fan. One curious thing we noticed is that your max supply cap falls the more players you play with, so while you still have more power due to the extra income, having more players isn’t a linear improvement.
I’ve tried “coop”, “co-op”, “co op” - no results. I can see that there are ungreyed-out blue boxes but the search never yields anything, even after 2 mins. There’s no content in those boxes, just the outline.
Yes, i am in the US server so the maps should also be there.
I also had the same problem as you so best thing you can do is wait for the search results for some minutes (1-2) if nothing shows up, reload the results again. It can be time consuming but it’s the best thing to do. I did the same and somehow got it.
The best keyword also appeared to be “coop” as pointed out.
Finally found it. 30+ minute wait for the result to actually load - from being an unfilled (but not greyed out) blue box to something with text and image. Not all the maps showed up in the search, that took a while longer.
And then another 10 minutes for “Create lobby” to get enabled (map dependencies).
