Space platform (Avernus)
Discord IV is a space platform orbiting Avernus that serves as an allied 4-player StarCraft II mutilplayer map. Controlling each of the center towers provides vision to more easily defend the side expansions. Check the other attack route before attacking, as opposing forces may be attacking through that route. Also note that rushes are easy to pull off as both bases share a single ramp.
A novice version exists.
It was removed from ladder on season 8.
