StarCraft: Mass Recall is one of those absolutely wild mods: a full remake of StarCraft 1 and Brood War in StarCraft 2, complete with new models and cutscenes. Since StarCraft 2 is now free-to-play, that means this long-running project is as well.
We first reported on Mass Recall all the way back in 2015, when the mod was just one year old. At that time, you could already play the entire SC1 and Brood War campaigns, as well as three "hidden" maps, but the project has grown and developed in substantial ways in the past nine years.
